Across
  1. 2. change this refers to the sudden volume change in crystalline quartz particles experience as they pass up and down through 573C
  2. 3. dunts fired ceramic bodies as a result of a thermally induced stress
  3. 6. combining two or more things together into one
  4. 7. ware that has been fired once and has no chemically bonded water left in the clay
  5. 9. of molten glazes typical bisque fired pottery a raw or partially fritted glaze works well at a specific gravity
  6. 11. a firing defect in which blisters form within a clay body, causing large lumps on the surface.
  7. 12. firing The final aim is to heat the object to the point that the clay and glazes are mature
  8. 13. a kind of lead-glazed Japanese earthenware, typically irregular in shape and used especially for the tea ceremony
  9. 14. out release carbon as they decompose on heating
  10. 15. glazing where you glaze the inside of your greenware pot when it is leather hard and then the outside when it is bone dry
  11. 18. a crystalline form of silica formed in the matrix of clay bodies as they fire in the kiln
  12. 19. dunts ware cooled too quickly after it has been fired
  13. 21. firing the glaze melts on the fired body and forms a vitreous surface.
  14. 22. produce a network of fine cracks on a surface
  15. 23. fit the thermal expansion compatibility between glaze and clay body
  16. 24. cracking that occurs in fired ceramic bodies as a result of a thermally induced stress
  17. 25. removal of water and solvent
Down
  1. 1. this is the period in the kiln firing where the final mechanical water is being removed
  2. 3. action lower the high melting point of the main glass forming constituents
  3. 4. a rare silicate mineral of post-clay genesis
  4. 5. core occurs during a reduction firing and is a result of fast firing and/or lack of oxygen in the kiln between 700 and 900C
  5. 8. a glaze quickly can prevent the elements that would make up crystals from rearranging themselves into the crystals
  6. 10. process for ceramic materials are determined based on the nature of the matrix
  7. 16. the progressive partial fusion of a clay, or of a body, as a result of a firing process
  8. 17. firing to any pottery that has been fired in a kiln without a ceramic glaze.
  9. 19. the collapse, disintegration and deforming of clay from over-firing
  10. 20. smoking to the period in a kiln firing where the last of the mechanical water in body are being released
