Across
- 4. Cone 5-11. high-fired vitreous ware - as hard and as durable as stone
- 6. uneven mixture of completely dry clay broken down into small pieces and added to water
- 9. chemically made up of alumina and silica but is represented by term 'alumina', Al203
- 12. material that melts clay and silica in clay or glaze
- 13. Cone 04-1. usually porous ware but can be dense and hard below 2000F
- 14. HARD describes clay that is not wet, still stiff and cannot be bent without cracking, stage in drying for handle attachment and carving
- 15. or engobe - clay solution usually containing 50% water, which may be combined specially or made from the same clay as the clay body, used under glazes or alone, rarely over glazes
- 16. Silica, glass former in clay or glaze, Si02
Down
- 1. made of three main ingredients: clay, flint, and flux, shiny covering on pottery, usually applied after ware has been bisque fired
- 2. oxidized, in the form of powders to colour slips and glazes
- 3. simple glaze usually containing a toxic or solution that is fired to a glass, then crushed into a powder to be used as a flux in glazes
- 4. to disintegrate into water - simplest way of breaking raw clay down for future preparation
- 5. used in mixing and straining slips or glazes, also called a 'sieve'
- 7. resistance to melting or heat
- 8. DRY clay that is ready to be bisqued, easily broken and crumbly a this stage
- 10. commercially compounded colourants made to yield other, more subtle, colours that are otherwise not obtainable with straight oxides
- 11. the preparation of plastic clay - involves mixing and compressing. used to remove air pockets, mix clay thoroughly, aligns particles
