How to document glaze defects
Record surface type, location, clay body, recipe, thickness, application, cone, schedule and kiln position.
Procedure
- Record surface type, location, clay body, recipe, thickness, application, cone, schedule and kiln position.
- Separate observation from cause. “Small craters on the floor” is an observation; “cooling was too fast” is a hypothesis.
- Change one controlled variable in the next test and keep a comparison tile. Do not transfer advice blindly across bodies and firing ranges.
What to record in CeramikaTo
- Work or sample code and date.
- Material, batch, cone, schedule and position.
- Observation separated from hypothesis.
Common mistakes
- Changing several variables at once without a control sample.
- Missing batch, cone or kiln-position information.
- Treating an estimate as a guarantee.

FAQ
Can I use this procedure for every clay?
You can keep the record structure, but parameters must come from your tests and manufacturer data.
