clé guild fundamentals is a locally produced, artisan tile line created in clé tile’s san rafael guild. clay for this line is sourced from the base of the sierra nevada foothills. minimally processed, this rugged material possesses natural mineral inclusions which when fired, make every tile a truly unique expression of the earth from which it is made. glazes are formulated of natural minerals and pigments, giving each kiln load a small batch, hand crafted feel. clé guild fundamentals are available in white and black in both matte and gloss surfaces. at once rustic and elegant, fundamentals are an elevated glazed brick alternative to classic subway tile.
