Water absorption - WABS

This test procedure was employed in the Foresight Ceramic Database and now is available for those having an account at Insight-Live.com. Accumulating test data using the variables defined in these procedures enables us to create tools that enable you to compare the physical properties of materials and recipes.


An indicator of the density and therefore degree of vitrification of a fired clay body. Typically a body sample is fired at a range of temperatures and absorption measurements are done on each to produce a graph of porosity vs. temperature. Absorption is measured by weighing a bar before and after boiling in water and calculating the percentage increase in weight. Use the SHAB test to compile this information.


VAL - Value (V)

Enter the percent porosity and temperature
