WebbPLASTICITY Plasticity has to be our first consideration. You can’t begin to make pottery without it. To be usable, clay has to have the ability to hold its form while at the same time be pliable enough to be moved by the potter’s hands. This is plasticity, and it is determined by the size and shape of very fine grains or WebbBecause some ceramic raw materials have a lower plasticity index and affinity for water than clay, they need organic additives adding ahead of sintering. The process is associated with material shrinkage as the glass phases flow once the transition temperature has been reached and the powdery structure of the material consolidates, reducing the material … squeeze a burp toy
