- 2. it makes clay bodies resistant to breakage or damage during handling in production
- 4. Combining clay and cellulose fiber from paper produces a versatile clay body that can be molded, modelled, slabbed and coiled in ways that seem to break all the rules of working withclay, and by people possessing little skill
- 5. openers -(sawdust, chopped straw, dung, etc.) Burn out when fired and leave behind spongy holes. Give texture, working strength to plastic clay, and reduce thermal shock cracking
- 7. is a number that appears on the data sheets of ceramic materials. It refers to the amount of weight the material loses as it decomposes to release water vapor and various gases during firing.
