Porphyry
Porphyry is a volcanic rock and is formed during a slow cooling process of igneous material, giving it high compressive strength and density. Porphyry can be sourced in various colours in particular earth tones of grey, brown, rust, buff and violets. Porphyry can be sourced from various countries around the world although Italy has become the main attraction with areas to the north of the country most popular. Other countries able to supply Porphyry include China and Argentina.
Over recent years Porphyry has become a popular architectural stone with Planners and Specifiers alike, in particular for projects needing an edge of quality or a subtlety of tone. It is an ideal surfacing material for walkways and town regeneration schemes, but also lends itself to domestic applications too.
