3 Ceram-technological behaviour (secondary properties)
The primary properties of a clay or a batch result in a definite ceram-technological behaviour, which can be simulated under laboratory conditions or partly on pilot scale. The ceram-technological tests serve as a basis for the design and the optimization of dryers and kilns, the development and optimization of batches or the detection of firing faults.
3.1 Preparation and shaping
According to  the main demands in ensuring the plastic mouldability of heavy clay materials refer to
