Porphyry is a natural stone the beauty of which derives from its multiple colours. The colour descriptions indicated above identify the gradations of the main tone, but porphyry’s colouring is always a mixture of colours.
Porphyry’s features can be summarised as follows
High abrasion resistance, which provides for an anti-skid surface even in the presence of water;
High resistance to wear, that prevents the product from ageing;
Very regular natural surface, that makes it comfortable and pleasant underfoot and that maintains its natural colouring over time;
Low absorption of water and of other substances, which means high resistance to frost and to other elements that could modify its physical and mechanical properties;
Irrelevant maintenance costs over the medium/long-term.
