What is ceramic and how do I colour it?

Ceramic materials are defined as metal oxide-containing, inorganic, >30% crystalline and poorly water-soluble materials. This results in their generally high hardness and brittleness and also their relatively high melting point.

Typically, ceramic materials are manufactured in a firing process in which sintering occurs above 1,200°C. This gives the ceramic its solid physical form.

Due to the high temperatures of the firing process, only inorganic pigments are suitable for colouring ceramic products. There are colour changes here, but these are very often deliberately used for the design of the product.
