Across
  1. 1. Greenware that is no longer pliable, but may still be carved. Feels cool to the touch
  2. 6. A saucer shaped prop used to protect kiln shelves from particularly runny glazes
  3. 8. A powerful machine that homogenizes moist clay into a workable consistency
  4. 9. A heating chamber to fire pieces
  5. 11. A flat shelf that can hold clay pieces inside a kiln and is capable of withstanding extreme temperatures
  6. 12. clay with extra liquid used for bonding and decoration
  7. 15. A combination of clays and other additives to create a usable material
  8. 21. a secondary surface treatment that is applied on top of fired glazeware
  9. 22. A kaolin-heavy pure clay that is fired to a higher cone and is vitrified into a near-sealed surface. Prized for its (usually) white and sometime near translucent appearance
  10. 23. Roughing surfaces to prepare two points to be bonded
  11. 24. A kiln type when the air inside is not altered and oxygen is present
  12. 25. Rubbing an unfired piece with a smooth object to align and compress the clay particles and create a smoother and/or stronger surface
  13. 29. A surface treatment with a layer of pigment slip painted on, then carved away in certain areas to create patterns/images.
  14. 30. A traditional Japanese style of firing that has been brought outside Japan and altered. Pieces are removed from the kiln at their top temperature to alter the final surfaces.
  15. 31. Formed by unfired clay. Will still dissolve into reclaim
  16. 32. Unglazed clay that has been fired once and will no longer dissolve into reclaim
  17. 33. a surface treatment that does not seal the surface and can be applied at various stages in the process
Down
  1. 2. a special slip like material of particularly fine clay particles
  2. 3. A sheet/slab to go under a larger piece of work made of the same clay body
  3. 4. Caused by mismatched glaze and claybody where the glaze contracts and the clay expands. Results in bare spots
  4. 5. Tubular supports that hold up kiln shelves and are capable of withstanding extreme temperatures
  5. 7. A system of measuring total heat (not just temperature) used to reference targets for particular clay bodies and glazes
  6. 10. Pulverized minerals. Alumina, Silica, Water
  7. 13. a gypsum based material that acts as a hard sponge
  8. 14. a blend of clays, glass formers, pigments, etc to create a surface treatment that coats and seals a surface
  9. 16. Caused by mismatched glaze and claybody where the glaze expands and the clay contacts. Results in cracks and flaking
  10. 17. A coating put on kiln shelves to protect them from glaze drips
  11. 18. Greenware that is completely dry and at its most fragile state. Feels room temperature.
  12. 19. A kiln type where the air inside is altered to reduce the amount of oxygen to produce particular colors in glazes
  13. 20. A clay-like material used to prop up pieces in certain types of kilns
  14. 26. Unfired and discarded clay that is kept in water to eventually be reused
  15. 27. Clay that is fired to a higher cone and is vitrified into a near-sealed surface
  16. 28. Clay that is fired to a lower cone and is still porous
