Porphyry is a magmatic material formed by the cooling of a lava flow with a very varied, complex composition on which a structure is created that also includes minerals and crystals. This particular characteristic is reproduced by Coem on a stone effect porcelain stoneware that shows a thick-grain agglomerate. The original appearance offers a new, slightly retro look for settings, in which vintage furnishings can be mixed with authentic designer elements. Ideal for the floors and walls of both residential and commercial environments.
