Glaze test tiles step by step

The tile should represent the actual clay body, surface preparation and application thickness. Add texture or grooves to show pooling and edge behaviour.

Procedure

1. The tile should represent the actual clay body, surface preparation and application thickness. Add texture or grooves to show pooling and edge behaviour.
2. Record batch, cone, atmosphere, kiln position, coats, application method and any underlayer. Colour alone cannot reproduce a result.
3. Keep the physical tile with a durable code linked to the CeramikaTo entry. A photograph supplements rather than replaces inspection.

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.
