These tiles are made from clear and transparent low-iron molded glass inspired by the crafted glass production on the Italian island of Murano. Whether using a brick pattern or straight stacked application, they will complement any kitchen, bath, office, living space, or pool. This stunning and unique glasswork is distinguished by its smooth finish, clean lines, and beautiful shine. The back of the glass tile is coated with the desired pigment(s) and a white protective coating is visible from the back of the tile. The multi-layered protective coating is fired with the tile and ensures that thin-set mortars will not be visible after installation. Pigments & glass are made from natural minerals and as such the firing process will cause slight variations in shade & size.
