Quoted on bentonite data sheets. The liquid limit is the water content above which the clay shows liquid behavior (essentially no shear strength). It is generally done as part of soil analysis and is related to plastic limit (water of plasticity) and shrinkage limit. The liquidity index and plasticity index can be calculated from these measurements.
Apparent Viscosity (cps)
Water of Plasticity
A physical data value quoted for plastic materials (clays) used in ceramics to indicate the degree to which they will add plasticity to a body.
Test conducted primarily on materials use to make bodies or glazes.
