Ceramic Glazes

What are ceramic glazes?

The main use of ceramic frits is the production of ceramic glazes. When glazes are applied onto the surface of the ceramic tile and after fired, they give an impermeable, protective and decorative layer to the tile, giving the ceramics their own beauty and their inner technical characteristics.

There are different kinds of glazes, depending on their physical state and their packaging system. They are mostly composed of frits, raw materials, additives and ceramic colours.

How are they produced?

In the glazes production the components are individually weighed and then mixed in a recipient. The compositions may be sent to the client like that (solid state), or in a water-base suspension, called ‘barbotine. They can also be dry-milled and used dry or in a water-based suspension for special applications.
