Ceramic Tile
Ceramic tile is undoubtedly the most common covering used in architecture and decoration of residential and commercial places. The use of ceramic tile has a long history from 4000 BC in Egypt to the use of spaceships in the present era. Ceramic tile has a key role in the architecture of residential places due to the creation of a beautiful facade and as a common covering.
Ceramic tiles can be used in homes as wall decorations, on kitchen counters in restaurants, around bathtubs and showers, around fireplaces, etc. Hot water pools and saunas, roofs, garden walls, patterned pediments of houses and even decorative patterns on the outer walls of houses make it beautiful. The very wide spectrum of color, design, size and role of tiles makes it possible to design and decorate all types of traditional and modern buildings.
A tile is a ceramic product that becomes semi-glass due to being baked at a certain temperature, so that its water absorption property is very low and it gains the necessary resistance against abrasion, pressure and mechanical impact. It can withstand sudden changes in temperature (20 to 100 degrees Celsius) without any cracks appearing in its body or glaze.
If one surface of the tile is covered with mineral glaze, the tile is called glazed.
