Porphyry, a rock formed by the cooling of volcanic eruptions from ages ago, is replicated by Moss, with the imprints of moss marks left on the surface. This creates an organic fusion of the rock and sparse vegetation, reflected in darker tones that sometimes appear on the material. This series offers a charming rusticity that characterizes porphyries. The chromatic balance among earthy colors can be used in indoor floor and wall applications, as well as exterior wall applications. The 3" x 9" Brit can be used on interior walls only.
