Q 2329: Email me relevant information on Lochabriggs stone. Joe, July 29, Reply

R1: Dear Joe, LOCHARBRIGGS (not LOCHABRIGGS) SANDSTONE, Sandstone is characterized by red or pink colouring, and it is medium grained in texture, free of clay holes and other impurities. The stone is quarried from the outskirts of Dumfries in Scotland. It is a Permian Sandstone. Daniel, Slovakia

Q 2321: Have you heard of a granite called "marron castor"? I am unable to find any information about it. Thanks, Carol, July 28, Reply 

R1: Dear Carol, MARRON CASTOR (BROWN CASTOR, MARROM CASTOR) is granite from
Brazil with brown (sometimes brown-reddish) color and almost homogenous structure. Daniel, Slovakia

Q 2314: I have purchased Uba Tuba tiles for a Kitchen Counter tops. Where does it come from, is it suitable for Counters? What's it's geologic information or history? July 27, Reply

R1: Dear Sir or Lady, UBATUBA is the Brazilian charnockite from end of the Proterozoic (about 600 million years). The charnockite is the special rock of granite or syenite composition in which there are feldspars,
quartz and pyroxenes. Daniel, Slovakia

Q 2271: We are currently renovating our kitchen. Our style is modern, our cabinets white hi-gloss acrylic. We want a stone countertop but neither of us like granite very much. I really like marble, especially the veined Calcutta Gold but understand that it isn't appropriate for a kitchen countertop. Can someone out there recommend either a veined granite (if it exists) or an engineered quartzite or any other stone with veining that is durable enough for a kitchen countertop? Ideally, I would love a white, beige, orange or blue kitchen countertop. Also, can you use sandstone or marble for a kitchen floor? We are looking to buy these products for a reasonable price in the Manhattan area. I've also been trying to find a large store where I can get a look at a wide variety of stone countertops in the tri-state area. Know of any? Many thanks, Ros, July 20, Reply

R1: There are two schools of thoughts about marble:
1) "All you can do with marble is just look at it. You can't touch it with anything!"
2) "My uncle Tony had a white marble worktop in his bakery and he was using and abusing that stone every day of the week and twice on Sundays. It looked good all the time!"
Now the $64 question is: Who's right?
Strangely, the answer is: Both!
It all depends from how each individual feels about the "looking good" expression. Neither Europe, Northern America (just to cite two of a long list of geographical areas) have very little stone culture, and the idea of most people from those areas about marble is that it has to be as shiny as possible and its surface totally unblemished. To the relative of Anthony the baker, their uncle worktop looked great because they grew up in an environment where the predominant perception is that the more a stone is beat-up, the better it looks!
Now, Ross, you have to decide in which school of thoughts you and the other members of your family belongs. If you belong to the former, stay away from marble (and any other calcite-based stones) -- Calicatta Gold, or what-have-you -- as much as possible. If you belong to the latter, then a "beautiful" hone-finished Calicatta Gold countertop (very low-hone, with no reflection whatsoever) is "your man". I can't decide for you.
About all the other stones you have in mind, I'm no interior decorator. Certainly you do NOT even want to look at sandstone!!

Q 2257: I would like a list of some stones and/or rocks that are porous, but would release oils over time. Thank you, Sherry, July 19, Reply

R2: I am a marble restoration professional who also has over twenty years of experience in the oil industry. I can say without fear of contradiction that most petroleum geologists spend their entire careers trying to answer this question. Very few are consistently successful. Sorry, but I doubt that there are any contributors to this site who can advise you on where to drill your next oil well. Good Luck, Mike, USA

R1: Dear Sherry: I don't know if this is because of the fact that English is not my original tongue, but, quite honestly, I have no idea of what you're talking about. Stone releasing oils over time??!! why Could you please elaborate for me? Ciao and good luck, Maurizio, USA

Q 2247: I've got a stone sample from a shop in the UK (though they're not around anymore) with the word 'Gaban' on it. I like the stone, but want to find out more about it. Where can I buy it? Any thoughts? An hour on the web has revealed nothing! July 16, Reply

R1: Dear sir or lady, The GABAN stone is a very strong, pale grey, fresh microcrystalline limestone with some variations in grain size notable by the presence of quartz and/or clay-bearing bands cutting through the material at a shallow angle to the bedding. It is product of stone quarries in England. Daniel, Slovakia 

Q 2241: Please inform if you do know anything about the following types or names of stone and marble, or are they fantasy names. In the past twenty years of my experience in this field I have seen many alternative names given to  natural stones. Could this be the same case? MEUCHATEL MARBLE, MARILU STONE, GREEN ROMINA MARBLE. I hope to receive any information that can be useful. Farah, UAE, July 15. Reply

R1: Dear Farah, I think MEUCHATEL is distortion from NEUCHATEL. Some limestones for building purposes were quarried near Neuchatel lake in Swiss. I have never heard of MARILU STONE or ROMINA MARBLE, only of MALIBU migmatite from India. Daniel, Slovakia 

Q 2230: What is pinola stone & therma stone? Janet, July 15, Contact

R1: Dear Janet, PINOLA STONE or Pine Stone comes from Georgia, USA. This probably calcareous sandstone has a white background with blends of caramel, purple, red, and blue all mixed throughout. This type for stone can be used as a stack stone, veneer, for patio, walkway flagstone, landscape stone, or for a water feature environment, and also for interiors. I have never heard of THERMA STONE. Therma floor is a gypsum under layment designed to pour over hot water tubes or electric heating cables. Daniel, Slovakia

 

A 2131: I have chosen a granite that the local supplier identifies as Verde Butterfly Canadian -- it doesn't have the white like "Verde Butterfly" - it has more yellow, plus there are some red stone chunks that look like garnet. 
It's a beautiful stone, but they may not have enough slab to do my entire kitchen and they probably will not be able to obtain more stone. The island is huge and I would prefer slab for that, and would be willing to compromise on back counters.
So, my questions are: 
Do you have any suggestions for a complementary surface if they can only do the island with the slab?
Do you have any suggestions on obtaining more of this stone, or how I could find out if anyone out there has tiles of the same stone (I would be willing to use granite tiles on the back countertops)?
I'm located in Boise, ID if you have any suggestions that would help me out, they would be greatly appreciated. Killee, June 28. Reply

A 2061: Please help me with any information available of the stone called Valentino Semi Classico, it have any other name perhaps? Thank you, Gio, June 14, Reply

R1: Dear Gio: The only "Semi classico" I know of, is an Italian compact limestone (traded as marble, by the name of Botticino Semi Classico. If that's "your man", it's a beige colored stone, it's quite hard (for a marble) and quite dense, too. It doesn't take a polish uniformly (it shows several natural dead spots -- no crystallization, that is -- that will not polish), like its brethren Botticino Classico does.

A 2017: I thought that Breccia Oniciatta was an Italian Marble, but I don't see it on the find a stone under the Italian stones. Where can I find a picture of it? Margaret, June 4. Reply

R1: Dear Margaret: I really don't know where you can find a picture of it, but I can tell you 
two things:
1. "Breccia Oniciata" is indeed an Italian stone traded as marble. 
2. Assuming that you can find a picture of it, it won't do you much good. 
There are so many variations between different batches of that stone, that even myself -- who've been dealing with that particular stone since puberty(!) -- have a problem recognizing it for what it is some times!
The best thing to do if you're interested in that particular stone, is to go to few dealers that carry it, examine what they have in stock (not just the display in their showrooms), and when you see the batch that you like, just grab it and buy plenty of spare tiles!

A 1999: I recently bought this stone for a backyard patio. I was wondering if you could identify it and tell me where it comes from. I live in central Texas, I was told by one that it was Mexican and another it was from Oklahoma. I am attaching pictures. Thanks for the help! Eric, June 1, Reply

R2: Dear Eric, your samples are the most probably TEXAS CREAM LIMESTONE. Fossil of belemnite is probable on one bed surface. The limestone is probable of Cretaceous age. Daniel, Slovakia

R1: Hi Eric. Can't really be sure without actually seeing the stone, but it looks like one of the sandstones that come out of Arizona and Utah. I too am in central Texas, so you can contact me through this web site. JVC, USA 

A 1981: Recently, I went to a showroom to choose a granite countertop for my kitchen. 
Among the items present was a green granite from Brazil that was referred to as "Amazon" by the storeowner. Searching pictures on the world wide web, the only "Amazon" I can looks nothing like what I saw. In fact, I have seen no granite from Brazil (or Argentina, Portugal, Spain, or India) that has the look of what I saw. 
The polished granite slab that I saw appeared to be waves of medium green against a lighter green background. Pinkish dots were sprinkled in places. In appearance, the granite almost looked like mountains of dark green against a lighter background. I was told this granite was relatively new (at least to this importer).
Do you have any idea what granite I was looking at? The question is more than academic because I am trying to decide between Amazon granite and an UbaTuba--I know the Uba has good resistance to staining etc. and is a standard choice for countertop. I would like to find out more about the other choice before taking the plunge. Thanks for any help you can provide. 
I have searched the Internet exhaustively and looked at many green granites from Brazil; either the sample I saw was an oddball piece, or it just wasn't present on any of the many web sites I checked. Art, USA, May 28. Reply

R1: Dear Art: Never heard of "Amazon". The way you describe it sounds to me like "Verde  Lavras", but it has no pinkish dots. So I really don't know. Ciao and good luck, Maurizio, USA 

A 1964: I am a newcomer to this arena and I am thinking about buying a granite called Ocean fantasy for a kitchen countertop. I have been to different places and they are mostly gray with white swirls, with considerable variation. Can anyone tell me more about this granite for this use? Robert, May 25, Reply

R2: Dear Robert, OCEAN FANTASY is migmatite (granite gneiss) from Brazil. Such stone type is very changeable, but suitable for the countertop. Daniel, Slovakia

 

A 1898: Daniel, John, Maurizio, Greetings from a fellow geologist. We just installed a LOT of stunning Juparano Colombo (a remobilized orthogneiss in this case) in our house. Everyone is asking me where it is from- in the geological sense. My fabricator has no idea and what little I can find on the web indicates either Sri Lanka (unlikely), India or Brazil. Not much help there. Of course I know that whereever it came from- it spent some time at what looks to be maybe 6 to 8 kilobars with right lateral shear ;) Gentlemen- I welcome any info you can provide so that I can learn more about this stone- where is it being quarried today, etc.? Thank you, George, May 15. Reply

R2: Dear Geroge, JUPARANA COLOMBO migmatite was originally quarried in Sri-Lanka. Later similar material was found in India (Tamil Nadu, Thogaimalai) and this is now quarried. The rock was formed during the Proterozoic. Daniel, Slovakia,

R1: Dear George: Greetings back from Maurizio! By the way, where do you live and operate?
That said, the original Juparana Colombo was indeed from Sri-Lanka, but local political unrest lead to the shutting-down of the quarry. The "Juparanas" you can find today are coming either from India or from Brazil. They don't look exactly like the original one, but ... What can one do! Ciao and good luck, Maurizio, USA,

 

A 1843: Hi guys- I am a sculptor and a stone carver. Is there a dark or richly veined limestone that is even close in carvability to Indiana Limestone? Thanks- Dale,May 14.Reply

 

A 1824: Hi- I love the website- loaded with info... I am looking at purchasing granite kitchen countertops and am more confused then ever. How can you tell what is/isnt granite when the sales people are telling u it is granite??? I am looking at Florence Rose and Golden Viara(?). Thank you, Darlene, May 14.Reply

R2: Unfortunately you can't. Many people who sell stone counters wouldn't know what is granite and what is not. Simply stated true geological granites represent 2-3% of the stones used for counters. The granites were used first so most mercantile outlets used that designation to make things simple. Unfortunately again, it confuses rather than simplifies.
The Golden Vyara is a gneiss that is typically resined so it may do just fine in the kitchen. Use the absorption test (lemon juice test) to assess. The other I am not familiar with. That is the second problem there is not a true standardized naming process that appeals to everyone for one reason or another. Regards, Steven, USA,

A 1713: Geological info on Juparano Colombo? Does anyone know the geological age, and actual location of the quarry so that I can search for geological research on the origin and history of this stone? George, April 16, Reply

R2: Juprana Colombo Quarry is located in Bangalore dist in the state of Karnataka in India. Nagesh, India.

R1: I think Daniel has answered this once before. The geological period is Neoproterozoic 
(1 – 0.55 Ga). It was originally quarried in Sri Lanka. It is a migmatite. There is a new  Colombo now and I forget where the new stuff comes from. Regards, Steven, USA,

A 1686: I am trying to find information on a granite slab called Australian Autumn Green. It is unusual in that it has large patches of predominately lime or spring green as well as other areas of dark greens, teals, browns oranges, and black. I have looked at many Web sites, but I have seen nothing like it. Could you direct me to a source of information, the appropriate name, and whether or not it is suitable for a kitchen counter. (I noticed that it looks as if a sealer was used in the polishing.) What is the light green rock? Also, I was wondering if decorative granite is checked for safe or no levels of radioactivity. JeJiv, 
April 10. Reply

R1: Dear JeJiv, I would say that the rock type you are describing is a coarsely porphyritic granite that is traditionally called Mulroy or Namban green. It comes from Western Australia about 200km north of Perth. It is a very hard granite - difficult to cut and quite abrasive. It is about 2,600 million years old and sits on the Darling Fault. Many episodes of hydrothermal activity from adjacent granitic and doleritic intrusives have produced the strange range of colours that characterize this rock type. Because this fault has been active for a long time the granite has been deformed (brittly) and then rehealed, hence the black lines (of chlorite) and the veinlets of sulphide. As for radioactivity, there is little cause for concern unless you intend to have a floor and walls of thick granite in a big basement with little air circulation. Much has been said about radon emissions and granite and the conclusion is that the principal source of radon is the rock on which your house is built. It is quite suitable for a kitchen top but you might have some trouble getting hold of some. (Dr. Hans), Australia,

Unfortunately, the hearth looks out of place (too blue) compared to the grays and tans/yellows of the other stones. I was planning on using a grout the same or near color of the hearth to tie the colors in but can not find the right shade. Anyone know a good retail source for grout dyes. I am also concerned that the result will be undesirable but want to give it a shot. Any suggestions on "turning" the color of the blue stone a little more gray would be appreciated.

A1498: Hi, My daughter is involved in a geology scavenger hunt with her 9th grade class. We have really found many of the items, but the one we are totally at a loss about is an item the teacher calls "mill stone". He said it can be found in gravel parking lots. I can find no mention of mill glass anywhere. Can you help us? Thank you. Sharon, USA, March 7, Reply

R4: Hi Sharon: I use Mill Stone on a regular basis. It is coarse sandstone from the millstone grit series. I assume it is the same in the US as geological terms are pretty much international. All the answers are correct also. I don't know what came first - the name for the stone or it's use in grinding mills. Bryan UK.

R3: In the UK, we have a type of sandstone that is referred to as Millstone grit, The particles that make up the stone are often random in size and angular. In fact, it is very suitable as a grinding stone or perhaps a mill stone?? You will need to look in a sandstone area & not a parking lot. Roy. UK 

R2: Mill stone is a block of stone which is chiseled round in a radius of 1' feet and the height is about 4". it has a hole in the center. It was used in a hand operated machine for grinding wheat. Harsha, India.

A 1456: I have been told that there are several different qualities of "crema marfil". If so, what are they, where does the best stone come from and how do I contact the quarry? Thank you, Gregg, Feb 19. Reply

R2: We have just finished cutting and installing a large bathroom in Crema Marfil so we have got to know it a bit better. Like most stones there are different grades but I am unaware of any distinct classifications. Generally in this marble the more veins it is the easier it will break. Unlike some marbles the minerals in the veins appear to be formed after metamorphism and in the case of this marble are sometimes very weak. A clue to be found on the rear of marble which have low vein strength is that there is often a matrix of fibre glass, jute or the likes, glued on to the back to keep it intact during handling. So you take your pick, ease of use or appearance. On the plus side, if installed correctly, once it is in place these loose veins appear to present no problem and it's appearance can outweigh problems of installation. It also scratches quite easily but they polish out easily. It is quarried in Spain and most wholesalers in Europe stock it and I presume but presume only that many in the US would also.

R1: Greg, I don't think you just contact the quarry. Try working with the dealers in your area first. If your project is large enough to warrant, take a trip to Italy.

A 1407: I'm in the process of purchasing marble/travertine for my bathroom. I have seen the tiles I would like buy. In one shop they called a terracotta tile Rosa Verona and a cream tile Botticino. I have also seen similar tiles in another shop they called the red tile Rosa Alicante. The business where I have placed the order (I have purchased from them in the past) call the tiles Rosa Travertine and Cream Travertine. Could you please give me your views on the names they have given each tile, and if they are all names for the same tiles, they all look very similar. I would describe the tile as a mixture of different shades of terracotta in colour with circular patterns (like stones compressed against each other) one tile had white markings). Barry, Feb 6. Reply

R2: Dear Barry: Rosso Verona is an Italian compact limestone (traded as marble). Rojo Alicante is a Spanish compact limestone (again, traded as marble. All compact limestone are). There are visual differences between the two stones, the most noticeable of which is the fact that Rojo Alicante shows some white veining, while the Italian stone does not. Travertine is travertine, period. Which means that is not a marble, and it's not a limestone. From a physical and chemical point of view it is very similar to compact limestone (plus the holes!). What makes it different from marble is that it's not a metamorphic limestone. What makes it different from compact limestone is the way it was formed. Ciao and good luck,

A 1395: I am an interior designer from Australia, who has moved to the UK. I am interested in finding contact details for a company I heard of before I left Australia. I'm sure their name or product is called Progrind- it is an in-situ process for installing reconstituted stone. I can't seem to locate them doing web searches- can anyone point me in the right direction. Thanks, Anne, Feb 1. Reply

R3: I have heard of the product Progrind. I think the material is an epoxy based grout which is used in fixing agglomerated stone. We can use a solvent less epoxy and mix it with quartz / sand in 1:6 ratio and use it. The consistency can be changed by varying the quantity of the
filler. This is the nearest to Progrind. Another alternative is a polymer modified ready made grouting powder, which is mixed with water and the slurry used for grouting. This is also equally good. If you require any further details on availability of either of the products, please contact me through this site. Regards Arun, India Reply

R2: Dear Anne, One mob who does this is in Australia is called Granite Transformations. What's wrong with the real McKoy? There is little price difference and real granite is superior in so many ways. Hans, Australia, Reply

A 1377: I stumbled across your website while trying to find pictures of serpentine and serpentinite. I found some material at the Morgantown Mine spoils dump in Morgantown, Pa that has me pretty well stumped. I found some large rocks (10-15 lbs) that had dark green bands running through them indicating there might be something inside. Some had lime green/yellow bands. I brought some home and broke them open with hammer and was surprised at what I found. The best specimen had a large green mass inside. I put that in my rock saw and came away with a chunk of rock that is dark olive green in color with roughly parallel wavy white lines. There are also red spots that make the rock appear to be bleeding. It has a slightly greasy feel to it.
I know that serpentine is found there at the spoils and I have found stuff that matches what I have read about it. So I am stumped. Oh ... I did get another fine slab of what I think is the same material but it is dark gray and looks like marble.
Attached a picture of the green material in case anyone wants to see it. Thanks, Paul, Jan 28. Reply

R1: Dear Paul, near Morgantown there are the mine of magnetite skarns with some content of Cu. Skarn is rock formed in contact of diabase and limestones. In your samples various minerals can be visible: diopside, phlogopite and garnet followed by actinolite, chlorite, talc,
serpentine, pyrite, chalcopyrite and abundant magnetite. Daniel, Slovakia Reply

A 1293: What is the trade definition of "Polished"? 2.What is the difference between "Buffed" and "Polished"? Thank you! Lise, USA, Jan 1, Reply

 

R2: 1) Polished- The end result in stone is the full range of color is seen in the stone. The surface will have a glossy appearance. The process is friction. Typically diamonds or silica carbide and pressure. 2) Buffed- Brings to mind the process used to apply a sealer like a wax. Applying a coating on top of a surface. The difference between the two is polishing is using friction to achieve a look. Buffing is applying a substance to achieve a look. Best regards, Steven, USA Reply

 

R1: Dear Lise: The definition of polished can be summarized as follows: A fine grinding action designed to smooth the surface of the stone to the point of producing a deep gloss. I honestly don't know the difference between polished and buffed. I just don't know what the latter means. What I do know is that stone can't be buffed. In fact, nobody buffs, say, a floor. One buffs the wax (or whatever else topical finish) that was applied onto the floor. There's no finish onto stone that one can buff, unless, of course, one applies one. But it takes specialty finishes, and special equipment and skills to do that. What's more, such a procedure is only meant to preserve the gloss of the polished stone, never to make it. I hope I answered your question the way it was meant. Ciao and good luck, Maurizio, USA Reply

R1: I answered my own question with a web search under "conglomerate and boulders and green"- and found the following by chance: The "Gaugain" is actually "Gowganda" from Canada- very interesting geology!
Middle Precambrian, Huronian Supergroup 2200 - 2450 million years ago Gowganda Conglomerate, Elliot Lake. The Gowganda Conglomerate is a very striking material. Generally it consists of rounded boulders and pebbles of pink granite and other rocks in a fine grained grey mud. The rock has a uniform hardness. breaking across the boulders and grey mud evenly. Geologists think that the Gowganda Conglomerate is a TILLITE, formed by glaciation during the middle Precambrian. In some areas dropped stones are found finely layered ( varved ) clays . This is the evidence for thinking that icebergs dropped the stones into the mud. Sometimes pieces of Gowganda Conglomerate can be found in gravel pits and at beaches along Lake Huron and throughout southern Ontario. This material was collected by glacial ice in the area illustrated during the Pleistocene Epoch, and transported to the south. Benjamin, Reply 

Daniel! how would I tell the Gaugain conglomerate from Brazil vs. this conglomerate called "Gowganda" from Canada? tricky ID question.....Benjamin Reply

A 1243: The Kentucky State Capitol Building,  built in 1904-1909. They have a red marble which I am to trying to locate the origins of and have looked at every sight I can find. I have not yet found the exact match. Any suggestions? Linda, USA, Dec 6. Reply

R2: Hello Linda! What do your red marble look like? Is it just red or is it red with cream veins etc...? Atkin, USA Expert Panelist, Reply  

R1: Linda, finding that elusive exact match may prove impossible, unless you can access some of the original building specs. Somewhere in the contracts, the source of the marble should be specified. But even then, chances are that the quarry has not produced stone in a very long time. Here in Texas, two very old quarries have been reopened on a very limited bases to provide stone for court house restorations, and I might add, it was a difficult task. Not being familiar with the geology of Kentucky, I can't say that a red marble was ever produced there, but I do know that a red or pink marble is produced in your neighboring state of Tennessee. That might be the source. But then again, the source may be in Europe. Have a good marble and granite fabricator (one who has access to a lot of stone) and get their opinion. Be prepared to send off small samples of the stone if at all possible to get an identification. But most of all, don't give up. Someone will know the stone, and where to get it.

We are losing many occasions for not being able to compare these unscientific names with the stones we may have available to meet the inquires.

R2: You can't. There are too many channels of distribution without any central body assigning names. Amusingly, some products are not even granite. Regretfully, Steven, USA Reply  

R1: Your request reflects a deep concern that is highly commendable. It is also, alas, as rare as an albino fly! On the other hand, it (your concern) is totally hopeless, because it's not "politically correct". The current establishment of the stone industry World-Wide is much against the disclosing of the different classifications of stones. For the "sake" of the industry, they want "to keep things simple", so that any idiot with a freshly printed business card can get involved in the stone business. In other words, they're trying to condense in a telegram format a whole science, namely petrography. Even if I did help you with a more scientific classification of the different stones that you have in your warehouse, my input would be totally unofficial, therefore toothless, and, therefore again, a total waste of time. Although based on scientific grounds, it would only represent my opinion. Is there anything that can be done about it? I do believe so. How to go about it is a different story, however I do know that it can't be expected from the recognized industry's authorities, unless the federal government kicks in a force them to. Long ago I reached the conclusion that the action must be  taken from without the industry's establishment and, somehow, eventually forced upon them. At that time I also reached the conclusion that I could not do it by myself. But then was then, and now is now. If something is ever bound to happen, we must all thank to site's like this one that represent the stone industry in real-life terms, through these open forums. Guys like me, by volunteering their time and expertise, have been having the opportunity to voice their opinions, by answering to all the gripes and disappointments of real stone end users, who've been literally victimized by the offspring of the general "politically correct" ignorance dominating the industry. Our answers and comments gave us more exposure than the "politicians" running the show ever hoped for. We're just at the beginning of a crusade that's way overdue, but I have the funny feeling that
someone is already getting a little uncomfortable. I do have what could be called a master-plan, and I also know that I can already count on the support of topnotch stone scientists and professionals. But I need more help. I need all the help that I can muster, and then some! And by "I", I really don't mean just myself. I mean all the true professionals out there who are sick and tired to have to compete with a bunch of quacks, just because the industry is unwilling to set any standard. I consider this as an open invitation to all the guys who participate to his forum: Let us all join forces and do something about it. There are ways, and I believe I know them. It will take time, years, but, if we're really determined to see it through, together we can do it.
Please do correspond with me, either directly or through this web-page. We can really help each other out for the benefit of our beloved industry. Ciao everybody, Maurizio, USA Reply

Nor I honestly care to: their names are scary enough to me, and I have the gnawing feeling that they kinda spell T-R-O-U-B-L-E. But if you're a stone dealer or an interior decorator of sorts you don't care about that. As far as the bonding (setting) material is concerned, I would ask the guys who sell them. Finally, about the "finish" thing, once again, I have no idea what you are talking about. Stone tiles are typically finished in the factory to either a high gloss, or to a hone finish, or flamed, etc. Ask the distributor what's available, have him / her show you samples, then make your decision.

R1: "Crema Marfil" is indeed compact limestone which is quarried in Spain. I comes in voluntary grading (in other words, to the good heart of the quarrier) dubbed "Commercial", "Select", and something else that I don't remember. It doesn't matter much, anyway, because the dealer has no legal obligation what-so-ever to disclose such (unofficial) grading to you. There's no difference between the Spanish, and Italian, and Iranian "Cream Marfil", because there are no other "Cream Marfil" but the one coming from Spain. I don't know about the Iranian one, but if you stumble upon a slab of "Cream Marfil" with the brand "Made in Italy" on it, it only means that some Italian stone processing plant bought blocks of the stone from Spain and processed in Italy.

A 1153: I work as a chief engineer at a historic London town house called Home House. The house was built in 1776 by the famous architect Robert Adam, during the twenties a magnificent marble bathroom was built using, as we first thought, a beautiful pinkish marble on the walls and in the shower area. As time went on and the hardness of London water taking it's toll, there have appeared not only the widening of fissures but severe corrosion to the lower panels in the shower areas. We have had a number of marble specialists to look at this problem and they have all said that it is not marble, that in fact it is ENGLISH ALABASTER. As this is not mined anymore we have limited options as to what to do. English Heritage have agreed that we can get a near replacement in a marble. What we need is your advice as to what type of marble would be a good replacement. We have three choices, either match it with the English Alabaster or match it with the border marble which is an antique Brecce Bernice type (this has proved impossible to obtain), or finally match it to the floor marble that resembles a Crema Delicato. This has now became a matter of great importance to get this bathroom repaired as we have had no operational shower for nearly a year due to water leaking through the alabaster wall into the rooms below.

If you are prepared to gamble, go ahead, otherwise try our traditional brown range from Australia.
