Across
- 2. a rare silicate mineral of post-clay genesis
- 8. includes drying of powder and shaped bodies
- 9. you glaze the inside of your greenware pot when it is leather hard and then the outside when it is bone dry.
- 11. used in glasses, glazes and ceramic bodies to lower the high melting point
- 13. the thermal expansion compatibility between glaze and clay body
- 15. a crystalline form of silica formed in the matrix of clay bodies
- 17. a fault that can occur during the firing of ceramic articles
- 18. the sudden volume change in crystalline quartz particles
- 19. the degrading of ceramics due to interacton
- 20. the glaze melts on the fired body and forms a vitreous surface
Down
- 1. the second firing of a piece pottery
- 3. consist of opaque matter that absorbs or scatters visible light
- 4. a firing defect in which blisters form within a clay body, causing large lumps on the surface
- 5. progressive partial fusion of a clay, or of a body, as a result of a firing process
- 6. when a substance in a product being fired has a lower burning point than what it is being fired with and burns away
- 7. formed by fusing inorganic materials into a glass by heating them
- 10. this is the period in the kiln firing where the final mechanical water is being removed
- 12. a flaw in ceramic ware attributed to the decomposition of iron pyrites
- 14. the degree of fluidity
- 16. any pottery that has been fired in a kiln without a ceramic glaze
- 19. the cracking that occurs in fired ceramic bodies due to stress
