Prerequisite: Metalsmithing 1


Lost wax casting is an ancient technique for making jewelry cast in metal from models made of wax.


During this two day workshop, students will learn how to utilize their flex shaft as a wax lathe. Students will turn a ring and a bezel setting in wax. Students will sprue up and invest, cast, learn finishing techniques and set their stone. The flask will be 'burned out' overnight.


The second day students will pour molten metal into the hardened investment (vacuum casting). When the metal cools, the investment is broken away to reveal the cast metal ring, which students will clean and finish and set their stone.



The Materials Kit is in addition to tuition and is payable to the instructor. Kit includes : wax rods, turning collet, Burs, Steel carving/ tuning tools, and other neccessary supplies, consumables and tools for use in completing project.
