Intro. ceramics powerpoint

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