Sample range
Review several pieces so color movement, speckle density and edge behavior are visible.
Glaze control
How to control reactive glaze variation.
Reactive glaze is beautiful because it moves, but buyers still need clear approval standards before bulk ceramic production.
Control method
Approve a range, not a single impossible perfect piece.
Defect boundary
Define what is acceptable variation and what becomes a reject, especially on food surfaces.
Repeat file
Keep approved samples, photos and notes for repeat orders and future quality review.
Inspection focus
Reactive glaze checks should be visible in the production file.
- Color range and glaze flow
- Speckle or pooling density
- Rim and foot ring behavior
- Pinholes, crawling and sharp defects
- Logo or decal clarity over glaze
- Carton grouping by acceptable appearance
