Metropolitan Ceramics produces high quality, unglazed 1/2" thick ceramic quarry tile for demanding commercial and residential, indoor and outdoor applications. Metropolitan tiles are made from a mixture of natural ingredients including clays and shales, very similar to that used in the manufacture of brick products. They are extruded through a die and cut. This extrusion process creates a much tighter/denser body than can be achieved through other processes. Once extruded, the low absorption tiles are sent through a drier and then hard fired in a kiln. Metropolitan quarry tile is a natural product with through-the-body color that won't wear off.
