Firing Shrinkage - FSHR
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.
A percentage value that represents the dry-to-fired shrinkage of a ceramic body. Typically a body is fired to a range of temperatures, each is specified with its shrinkage value.
For a comprehensive test to measure shrinkage and porosity, see the SHAB test.
VAL - Value (V)
Specify the percent and the temperature e.g. 5.3% @ cone 6

SHAB - Shrinkage/Absorption Test
As kiln temperature increases bodies densify (particles pack closer and closer). As temperature continues to rise, some of the particles begin to melt and form a glass between the others that pulls them even closer. Some of the particles shrink themselves, kaolin is an example (in the raw state part...
