Glaze running or sticking during the firing process is a common challenge for ceramic artists, but it can be effectively managed with the right techniques. Here are the most practical solutions:
1. Control Kiln Temperature: Overfiring is a leading cause of glaze running. Use a pyrometer to monitor the kiln temperature accurately and follow the recommended firing schedule for your specific glaze.
2. Apply Glaze Evenly: Uneven glaze application can lead to pooling or dripping. Ensure consistent thickness by dipping, spraying, or brushing the glaze uniformly.
3. Use Stilts or Supports: For pieces with intricate designs, place them on kiln stilts or supports to prevent glaze from sticking to the kiln shelf.
4. Test Glaze Compatibility: Some glazes are more prone to running. Test small batches before full-scale firing to identify potential issues.
5. Adjust Cooling Rates: Rapid cooling can cause glaze defects. Gradually reduce the temperature to allow the glaze to set properly.
By implementing these strategies, ceramic artists can minimize glaze-related issues and achieve flawless results in their work.
