Firing shrinkage
Calculate the change from dry to fired length.
How to use it
- Enter values from your measurement or equipment label.
- Calculate and review the assumptions.
- Record the result in a work, test or firing log.
Method
Shrinkage methods use measured dimensional change. Kiln cost is estimated from power, time and duty factor.
Limitation
This is an estimate. Verify it with a sample from the same material batch and firing schedule.
FAQ
Does this replace a physical test?
No. Materials and kilns vary, so the result is for planning and comparison.
Are values uploaded?
No. The calculation runs in your browser.
