Ceramic tiles are thin, flat slabs made from various composition
of clays and other inorganic raw materials. The tiles
are molded, dried, sometimes glazed or hand decorated
and then fired at high temperatures. The clay may be red,
white or clear. Depending on the raw materials, body color
will vary from whitish to shades of yellow to reddish
brown. In glazed tiles, the color of the body is unimportant.
In unglazed tiles, the natural pigment of the clay determines
the body color or pigments can be added to change it.
Ceramic tiles can be categorized as: surface, firing process
Surface category divided into three: Unglazed, Polished
and Semi Polished
