Understanding Cracking in Clay
Causes of Cracking
Cracking in clay occurs primarily due to drying too rapidly or unevenly. This causes uneven shrinkage, resulting in stress buildup and subsequent cracking. Other factors that can contribute to cracking include:
- Using clay with high plasticity (tendency to stick and mold)
- Firing the clay at too high a temperature
- Physical damage or excessive handling
Signs of Cracking
Cracks in clay can manifest in various ways, from hairline fractures to deep fissures. They may appear immediately after firing or develop gradually over time. If left untreated, cracks can compromise the strength and functionality of the clay piece.

Methods for Repairing Cracked Clay
Kintsugi
Kintsugi is a traditional Japanese technique that involves repairing broken pottery using lacquer mixed with gold, silver, or platinum powder. The repaired cracks become visible and are celebrated as a unique feature of the piece.
Epoxy Resin
Epoxy resin is a strong adhesive that can be used to bond cracked clay. It’s important to select a resin specifically designed for pottery and follow the manufacturer’s instructions carefully.
Clay Glue
Clay glue is a water-based adhesive that can be used to repair minor cracks. It’s easy to apply and creates a strong bond that is virtually invisible when dry.
Tips for Using Adhesives
When using adhesives, ensure the cracked surfaces are clean and free of debris. Apply a thin layer of adhesive to both sides of the crack and press them together firmly. Allow ample time for the adhesive to dry and cure.
