Prepare pieces for a Raku firing
Raku is dramatic, unpredictable, and a little dangerous. Preparation is everything: you won't have time to think once the kiln hits temperature.
Select your pieces
- Choose three bisque-fired pieces suitable for Raku
- Open forms work best (bowls, plates, wide cups); they survive thermal shock better
- No thick walls: thick clay cracks when it hits cold air at 1000°C
Glaze them
- Use Raku-specific glazes (they mature at low temperatures: cone 06 to cone 1)
- Metallic lusters, crackle glazes, and copper matte are classic Raku choices
- Apply evenly: inspect for thickness (too thick = bubbling; too thin = bare spots)
- Wax the feet as always
Final check before firing
- All pieces can survive thermal shock? (no thick sections, no sharp angles)
- Tongs can grip them safely? (practice the grip cold)
- Your PPE is ready? (heat-resistant gloves, face shield, closed shoes)
