Common questions about clay and ceramic firing
In pottery and glazing, materials, drying, glaze application and firing are closely linked. Here you'll find guidance on common questions about clay, engobes, underglazes, ceramic glazes, firing temperatures and firing defects.
What matters for good results
Ceramic products behave differently depending on the clay, kiln, temperature and application. Use the manufacturer's technical data as the basis for your firing schedule and the answers here as guidance for planning.
- Choose clay and glaze to match the firing range
- Let pieces dry completely before firing
- Apply glaze at the thickness specified by the manufacturer
- Test new combinations on a test tile first
Good to know: If you're looking for the cause of a glaze defect, photos and details on clay type, glaze, number of coats and firing data help with the assessment.
