Basic Ceramics2

  1. 1. <ul><li>Introduction to basic handbuilt </li></ul><ul><li>slab clay techniques </li></ul><ul><li>Level: 4th to 8th grade </li></ul><ul><li>Various curricular integration </li></ul><ul><li>Social Studies: Native Americans </li></ul><ul><li>& Ancient Cultures </li></ul><ul><li>Science: Soil and Chemistry </li></ul><ul><li>Math: Angles, Degrees, & Geometry </li></ul><ul><li>Religion: Biblical References </li></ul><ul><li>Lesson Plan by Noreen Strehlow </li></ul>Basic Ceramics Pt.2 Hard Slab
  2. 2. <ul><li>Equipment needed: </li></ul><ul><li>Enough clay for each student to create at least one small project </li></ul><ul><li>If you absolutely have no money, use a homemade Salt/Flour/Water dough. </li></ul><ul><li>Clay tools for blending, assorted forks, knives, pin tools </li></ul><ul><li>Rolling Pin </li></ul><ul><li>Newspaper and cardboard for rolling, cutting and transporting slabs </li></ul><ul><li>Two yardsticks or similar wooden slats </li></ul><ul><li>Plastic sheeting to protect table tops </li></ul><ul><li>Covered air-tight containers for clay storage & Plastic bags with ties for storing pieces </li></ul>Omyacolor Plastiroc Air Dry Clay
  3. 3. <ul><li>Students will roll the clay with a rolling pin which has been </li></ul><ul><li>aligned with two yard sticks, slats or other items of the same width </li></ul>
  4. 4. <ul><li>You can “McGiver” a slab cutting area by scrounging around the house </li></ul><ul><li>This might not be “pretty” but it worked! </li></ul>
  5. 5. <ul><li>Students will learn to use a 30/60/90 triangle to cut perfect right angles </li></ul><ul><li>Students may tape a specific length on the triangle to measure equal sides </li></ul>
  6. 6. <ul><li>Students will learn that this simple method insures that the slab is a uniform thickness </li></ul><ul><li>Students will cut as many slabs as needed for the piece (an uncovered box needs 5 slabs) </li></ul><ul><li>Students may use a pattern to create an unusual edge for a slab box </li></ul>
  7. 7. <ul><li>Students will learn to bevel the edges of each piece at a 45 degree angle </li></ul><ul><li>Students will learn to score the edge with a small pointed tool so that the slip will adhere </li></ul><ul><li>Students will learn to apply slip liberally to each scored surface that needs joining </li></ul>
  8. 8. <ul><li>Students will learn put the two scored and slipped pieces together and smooth the slip </li></ul><ul><li>Students will learn to add a coil to the blended joined area </li></ul><ul><li>Students will learn to further blend the coil into the joined area for strength </li></ul>
  9. 9. <ul><li>Students will carefully score and slip each additional area to be joined </li></ul><ul><li>Students will continue to add and blend coils to the joined areas for strength </li></ul>
  10. 10. <ul><li>Students will have to cover their pieces in plastic if they do not finish in one class period </li></ul><ul><li>Students will blend and smooth all joined areas completely and let dry when finished </li></ul>
  11. 11. <ul><li>Students will learn that large clay projects usually require a special clay press </li></ul><ul><li>Students will learn that these slabs are usually trimmed to the largest rectangle possible </li></ul>
  12. 12. <ul><li>Teacher will demonstrate all techniques </li></ul><ul><li>Students will listen and watch carefully before beginning their project </li></ul>
  13. 13. <ul><li>Students will plan out their project on paper, making a pattern to follow </li></ul><ul><li>Students will cut out and bevel the edges of all pieces needed for the project </li></ul>
  14. 14. <ul><li>Students will continue to score all the beveled edges </li></ul><ul><li>making sure to score partway onto the flat surface also </li></ul><ul><li>Students will then be ready to slip and add coils for strength </li></ul>
  15. 15. <ul><li>Once the pot is completely assembled it can be airbrushed with terra sigillata </li></ul><ul><li>while it is leather hard </li></ul><ul><li>This is not recommended unless you are capable of cleaning the airbrush </li></ul><ul><li>thoroughly when applying the liquid as terra sigillata may clog the brush </li></ul>
  16. 16. <ul><li>This piece has white terra sigillata brushed on above the blue mountain line </li></ul><ul><li>The piece is now ready for bisque firing </li></ul>
