Types and Characteristics of Tiles

The manufacturing process of ceramic and homogeneous tiles has undergone considerable changes in recent times. More automated methods have been employed in production and a wide range of tile products with different characteristics are available on the market for various uses.

 

The following section identifies some new developments in tile production and in particular rectified tiles, which can be used to achieve better workmanship quality:

  1. Ceramic tiles
  2. Homogeneous tiles
  3. Glazed tiles
  4. Rectified tiles

 

Ceramic tiles

Ceramic tile is a mixture of clay and quartz ferrous sand materials along with water. The special clays are mined from the earth, shaped, coloured and then fired in kilns. They can be coloured and the surfaces can be glazed either in a high gloss or matte finish. Most ceramic tiles have either a white or red body colour underneath the glazed finish.

 

Homogeneous tiles

Homogeneous tile is a form of ceramic tile composed of fine porcelain clays but fired at much higher temperatures than ceramic tile. This process makes homogeneous tiles denser, harder, less porous and therefore less prone to moisture and stain absorption than ceramic tiles. They have a consistent property throughout the entire section of the tile. For these reasons, most homogeneous tiles are suitable for both indoor and outdoor use. However they are harder to cut due to their density and hardness.

 

Glazed tiles

Tiles where the colour and pattern are achieved with glazes and the body of the tile may or may not have a similar colour. The body of ceramic tile, called bisque, may be coated with or without a glaze depending on its intended purpose. The glazed coating comprise of liquid coloured glass which is applied and baked to the surface of the bisque under very high temperatures. The liquid glass coating can be fashioned with texture and design. The main features of glazed tiles are ease in cleaning and protection of the bisque from staining.

 

Rectified tiles

A rectified tile has all its edges mechanically finished to achieve a more precise dimension. Unlike a typical factory-edged tile, a rectified tile is created by cutting the tile to size after the firing process. This creates precise 90 degree angle smooth edges. As a result, the tiles can be laid with consistent grout joints. Most tiles (homogeneous and ceramic) can vary in size (up to 1.0%) after the firing process but this can be substantially minimized by sawing or grinding the tile after firing.
