Bodies containing chamotte are recommended for the production of larger objects. Chamotte (fired and ground clay) stabilises the structure of the object. It prevents deformation and cracking during drying. The particle size and quantity of the chamotte in the mass depends on the purpose of its use. Fine (0-0.5 mm) particle size in a proportion of 25% is recommended for objects produced on potter's wheel. Larger (1-2 mm) chamotte particles in a larger (40%) proportion should be used for larger objects produced by freehand forming, pressing or ramming. In the case of stove tiles the quantity and type of the chamotte play a major role in determining the tiles' thermal attributes.
