Research on ceramic raw materials

The raw materials composition usually contains clay, sand and additives. Clay minerals ensure plasticity and compaction through a firing process at high temperature and products for permanance. Sand and some other additives cause the production mass to become more open, resulting in the wet shaped product being easier to dry and fire. Additives are also used, for example, to modify the colour of the fired product, or engobes and glazes are used in the surface finishing of products.

In order to obtain an understanding of the behaviour to be expected of clay (recipees), we can for example determine the particle size distribution, the chemical composition and/or the thermal behaviour.
