Intro. ceramics powerpoint-2012

  1. 1. Ceramics Creating Pinch Pots
  2. 2. Clay Made from earth, water and fire. Clay is different from mud, since it has plasticity. This gives it the ability to hold together while its being shaped.
  3. 3. Basic Terms Ceramics – Clay objects that permanently retain their shape after they have been heated to specific temperatures. Pottery – Functional Ware, such as vases, pots, bowls or plates, shaped from moist clay and hardened by heat.
  4. 4. Basic Terms cont. Wedge – A way of improving the workability of clay by reforming the mixture to make it homogeneous and even in texture while eliminating air bubbles.
  5. 5. Basic Terms cont. Kiln – A structure built to fire clay at high temperatures.
  6. 6. Basic Terms cont. Fire – Heating pottery or clay sculpture to a temperature high enough to render it hard and durable.
  7. 7. Construction Pinch method: Handbuilding Technique that involves squeezing the clay, usually between thumb and fingers.
  8. 8. Construction Coil method:Handbuilding techniquewhere rolls of clay areattached together to formpottery.
  9. 9. Construction Slab method: Handbuilding Technique that involves shaping ceramics from broad, flat, thick pieces.
  10. 10. Clay Stages Greenware – Unfired pottery or ceramic sculpture. Leatherhard – The stage between plastic and bone dry when clay is dried, but may still be carved or joined to other pieces. Bone dry – Stage of drying when moisture in the clay body has evaporated so the clay surface no longer feels cold.
  11. 11. Clay Stages cont. Bisqueware – Ceramic ware that has gone through the first firing at a relatively low temperature and still maintains its porous state. Glazeware – Ceramic ware that has been fired at a high temperature with glaze, which forms a coating of glass onto the surface.
  12. 12. Tools Fettling knife – A long tapered knife used for cutting and trimming clay. Loop tool – A small loop with a handle used to carve clay away.
  13. 13. Joining Techniques Score – Scratching the edges of clay before joining them together. Slip – A fluid suspension of clay in water used in joining clay pieces and for surface decoration. Bond – when two pieces of clay are pressed together to hold their connection
