- 5. What refers to any pottery that has been fired in a kiln without a ceramic glaze?
- 7. This is a severe glaze problem that occurs when a glaze is under too much compression
- 11. This is necessary for both glazing and body construction of products such as tableware, sanitary ware, and floor and wall tiles
- 12. This is the adsorption of a material that was previously removed from a surface
- 14. This happens when some parts of the piece of cermic drys out more quickly than others
- 16. the stresses of uneven expansion and/or contraction
- 17. This refers to the thermal expansion compatibility between glaze and clay body
- 18. This is where the molten glaze withdraws into 'islands' leaving bare clay patches
- 19. The decrease in size while drying and firing
- 20. a glaze defect of glazed pottery; Characterised as a spider web pattern of cracks penetrating the glaze, it is caused by tensile stresses greater than the glaze is able to withstand
Down
- 1. a liquid mixture or slurry of clay and/or other materials suspended in water
- 2. a thermally insulated chamber, a type of oven, that produces temperatures sufficient to complete some process, such as hardening, drying, or chemical changes
- 3. What is unfired clay pottery referring to a stage of production when the clay is mostly dry (leather hard) but has not yet been fired in a kiln?
- 4. What is a fault that can occur during the firing of ceramic articles?
- 6. What gives ceramic creations a soft glow that is similar to the finish on porcelain?
- 8. This occurs when too much stress is created in a piece of ware during the heating and cooling process
- 9. This is the casting process that starts with a wax injection
- 10. This is clay that is prepared but not fired
- 13. This is called when a clay, glaze, or glaze colors have been fired at a too high temperature
- 15. a impervious layer or coating of a vitreous substance which has been fused to a ceramic body through firing
