  10. 14. Search Topics <ul><li>Celtic Knots </li></ul><ul><li>Filigree </li></ul><ul><li>Lacework </li></ul><ul><li>Openwork </li></ul><ul><li>Pewter pendants/broaches </li></ul><ul><li>Calligraphy </li></ul><ul><li>Chinese & Japanese characters </li></ul>
  11. 15. Designs: Geometric forms Nature-based forms Alpha-numeric forms <ul><li>Metal must flow into all parts! </li></ul><ul><li>Pouring spout – sprue </li></ul><ul><li>Air vents – gating </li></ul>Designs must fit within the circle!
  12. 16. Pouring area (sprue) Air vents (must go upwards) Metal will not flow uphill!
  13. 17. Melting and pouring <ul><li>Molds must be COMPLETELY dry! </li></ul><ul><li>Clamp a flat cookie to the carved cookie, settle in the sand at a good angle. </li></ul><ul><li>Heat the ladle, don’t allow it to rest on the sand (the sand will absorb heat and take longer) </li></ul><ul><li>When metal rolls easily, pour while keeping the flame on the metal </li></ul><ul><li>Unclamp the two plaster cookies, remove the metal and dunk in cold water. Remember, it’s HOT! Use tools, not fingers! </li></ul><ul><li>If the casting is incomplete, remelt the metal and try again. </li></ul>
  14. 18. Hints for better casting <ul><li>Divide the jobs, one student to hold ladle, one to hold the torch </li></ul><ul><li>Don’t ‘toss’ metal into the ladle – it can splash out </li></ul><ul><li>Be sure all papers are clear of the casting area </li></ul><ul><li>Use a piece of plywood to protect the table </li></ul><ul><li>Have water ready to dunk hot metal (or to soothe burnt fingertips!) </li></ul><ul><li>The molds cast better when they’re warm, if you’ve got a toaster oven, pre-warm the molds for faster results </li></ul><ul><li>If the first cast isn’t complete, inspect for inferior carving, add pathways, or cast again while the mold is warm </li></ul>
  15. 19. Supplies <ul><li>Propane tank </li></ul><ul><li>Electronic igniter </li></ul><ul><li>Oil pan (feed pan) </li></ul><ul><li>Plaster of Paris </li></ul><ul><li>Bag of play sand </li></ul><ul><li>Casting pewter </li></ul><ul><li>Clamps </li></ul><ul><li>Tweezers </li></ul><ul><li>Ingot molds </li></ul>
  16. 20. Grading Criteria <ul><li>Linear quality of design, must be very open and fluid, consider movement , NO paperweights </li></ul><ul><li>Creativity of design </li></ul><ul><li>Craftsmanship of final product </li></ul><ul><li>Participation, Effort, & SAFETY </li></ul>
