Abstract
Visco-elastic properties of thick clay-pastes were studied by torsion method, and found that (1) Viscosity and elasticity of pastes are decreased with increased watercontent, and also diminish elastic property with much water-content, (2) The influence of water-content upon viscosity coefficient is less than elastic coefficient. (3) No relations are found between viscosity, elasticity, and plasticity of ceramic raw materials.
