Across
- 6. ceramic openers withstand thermal shock
- 7. any material added to a clay to give it a character and quality
- 8. combining clay and cellulose fiber from paper produces a versatile clay body that can be molded
- 9. provide ducts for the passage of the moisture drying out and thus the mass dries more uniformly
- 10. that about 2-4% of the mix is paper by dry weight
- 11. lack lignin which can contribute water resistance
- 13. without an opener they are difficult to handle on a wheel
- 14. it gives to be the fired quality of the clay
Down
- 1. are hollow and the tiny clay particles are able to fill them from the inside
- 2. become part of the clay body during firing
- 3. are needed from the 300-500C since significant smoke is generated
- 4. strength that makes it possible to create much lighter ware
- 5. slurry to a clay slurry in a proportion of 30 volumetric parts
- 12. burn out when fired and leave behind spongy holes
- 13. paper is added to give strength to raw clay for sculpture
