It may not be glazed either) and then baked in an oven. After all, it needs to be cooked to harden. Clay purity, baking frequency and kiln temperature are factors that affect the price and quality of tiles. The temperature of the kiln varies from 900 to 2500 degrees Fahrenheit. The lower the kiln temperature, the higher the porosity of the tile and the softer the glaze. Higher temperatures produce denser tiles and stronger glazes
