WHAT IS THE DIFFERENCE BETWEEN GLAZED AND UNGLAZED TILES?
Glazed tiles are coated with a liquid glass which is then baked into the surface of the clay. The glaze provides an unlimited array of colors and designs, and will not stain or fade. Unglazed tiles are essentially the same as glazed tile, except that their surface is not coated. Unglazed tiles do not show wear because their color extends throughout the tile, making them ideal for heavy traffic.
