Kilnshrink: Clay Shrinkage

About Kilnshrink: Clay Shrinkage

Group measured test bars by clay, firing and direction, then compare observed shrinkage and size a target from your own range.

HOW IT WORKS
1. Open Test Series and name the clay, firing and measurement direction.
2. Record wet, dry and fired lengths for each test bar using consistent units.
3. Review the mean and observed range, calculate a target-size range and share the measurements.

Existing shrinkage and studio planning tools remain available.

WHAT TO KNOW
Results describe the bars you entered; they do not predict every future firing. Lengths must be positive and nonincreasing from wet to dry to fired. Keep clay, firing and direction consistent when comparing.
