Buyer asks: What are the quality differences between Pietra Serena
and the darker grey stone?
Seller says: Thanks for
your reply - generally you will find that Pietra Serena has a higher perocity
rate ( I believe to be about 5-6%?) - than our pietra grigio - I have technical
data from the university of Parma - summarising it as "heavy, compact, hard with
high values of 1) compression breaking 2)ultimate tensile strength 3) impact and
4)frictional test. It is to be considered a frost proof
material.
