Glazed Porcelain

There is no difference between glazed and unglazed ceramic and porcelain tile, other than the fact that glazed tiles undergo an additional phase in the firing process. During this additional process, a layer of liquid glass is added to glazed tiles by means of very high temperatures.

Although glazed ceramic and porcelain tile are a little less robust in terms of density and thickness than their unglazed counterpart, they allow for a wider range of styles and colors. Glazed tiles also tend to be more resistant to staining, as they’re protected by a non-porous layer of liquid glass.
