  1. 3. A process of producing pottery by use of a rapidly rotating disk referred to as a potter’s wheel.
  2. 5. A manual process of preparing clay for use by a potter. Similar to kneading dough, wedging accomplishes three things: a) it removes air pockets present within the clay mass, b) it helps to align the individual clay particles making the process of throwing slightly easier and the clay stronger, and c) it is a final mixing process that tends to even out water concentrations in the clay as well as homogenize the various ingredients in the clay mixture.
  3. 6. Hard, dense mid-fire clay body.
  4. 8. A hand building technique where snake-like pieces of clay are placed in a spiral formation, thereby building a cylindrical shape.
  5. 9. Clay that has been fired once, removing chemical water.
  6. 10. A mixture of various materials and colorants, which are ground into a fine powder, mixed with water, and applied to ceramic pieces. This mixture, when exposed to high temperature during firing will melt and vitrify, thereby forming a glass-like surface that is fused onto the ceramic piece.
  7. 11. Any one of various techniques for creating ceramic objects that do not involve the use of a potters wheel.
  8. 13. The oven in which ceramic pieces are fired to convert them from unstable greenware into durable finished pieces.
  9. 15. A mixture of clay and water usually with coloring agents in the form of metallic oxides.
  10. 18. Clay that contains considerable free water, but enough has evaporated so that the clay pieces are firm enough not to bend.
  11. 20. A technique of building pots entirely by molding the clay with the hands without coiling, using slabs, or throwing. Called pinching because it usually starts by a potter inserting a finger into a ball of clay and pinching the walls to thin and shape the pot.
  12. 23. Dense, smooth high-fire clay body.
  13. 25. Any one of various techniques for creating ceramic objects that do not involve the use of a potters wheel. In this technique, the clay is pressed into thin slabs that are then cut, assembled, and shaped into the desired form.

  1. 1. The process of exposing ceramic pieces to high heat in order to convert them into durable finished pieces.
  2. 2. A general term that refers to any ceramics piece that is not purely decorative and has some intended use.
  3. 4. A group of minerals distinguished by the presence of alumina and silica (SiO2) in their chemistry.
  4. 7. porous, low-fire clay body.
  5. 12. dry Clay in which all free water has evaporated.
  6. 14. A naturally occurring inorganic substance composed of very small "plate- like" particles..
  7. 16. The ability to form or mold a piece of clay.
  8. 17. Any ceramic object which is complete in construction but has yet to be fired.
  9. 19. Like glass in appearance or physical properties.
  10. 21. The parent rock of clay. When broken down it produces feldspar.
  11. 22. Clay that has been coated in a glaze and fired to melt and adhere the glaze.
  12. 23. The porous nature of clay allowing the moisture to evaporate.
  13. 24. As used by the ceramicist, a claybody, is a combination of various types of clay, minerals, and other materials.
