DSHR - Drying Shrinkage Test
Specify the % water content. This is normally based on plastic length, thus to calculate:
( plastic size - dry size ) / plastic size * 100
It is easiest to make bars with a 100mm mark. Then the shrinkage is just 100 minus the dry measurement.
For a comprehensive test to measure shrinkage and porosity, see the SHAB test.
Variables
VAL - Value (V)
Specify the % shrinkage from wet

Firing Shrinkage
During drying, clay particles draw together and shrinkage occurs. During firing the matrix densifies and shrinkage continues. More vitreous bodies shrink more. |
