- 3. The explosion of clay in the kiln caused by sudden escape of steam resulting from rapid heating or presence of impurities
- 4. Comes from the Greek keramos, meaning "potters clay" or "burned earth"
- 5. Mixing and de-airing clay by slamming and kneading. Prevents air bubbles from forming, which prevents blow-outs in the kiln later
