Abstract
The shaping of traditional clay ceramic bodies depends on the plastic and flow properties of clay. The ease with which a clay—water mixture changes its shape depends on the water content (see graph, p. 66). Thus when the water content is about 50% a slurry forms that will flow like a liquid to fill all spaces in vessels and moulds at only 0.1 atm pressure. When the water content is dropped to 40% 0.4 atm is required to produce the same flow, at 35% it is 1 atm and at 30% it is 2 1/2 atm. At the pressures mentioned two separate portions of the same body will unite to form a homogeneous whole. Drier bodies will also do so but at much higher pressures, namely:
