Casting – Bill Harr (Back by Popular Demand)
William Holland – June 11-17, 2017,
This class will teach silver casting for beginner and intermediate silversmithing. The emphasis will be on production centrifugal casting, meaning techniques for high reliability. The class will teach centrifugal and vacuum casting, wax modeling, sprueing, investing, burnout, casting, finishing and polishing, rubber mold making and wax injection. Steam casting will be covered if there is interest. Waxes will be available, and students will learn to inject their own. We will not spend much time on wax model making, but students will have that opportunity. Students will learn to make cast silver embellishments for their silversmith pieces. Students may bring items they wish to make molds of. Pictures of previous student’s projects can be found at: https://gardenofsilverdelights.wordpress.com
Lab fee is $80. This covers waxes, investment, molding rubber, and incidentals and teaching materials. Students may supply their own silver. Casting silver will be available at $1/gram. Unused silver will be bought back at a discount. Students should expect to use up to approximately 3 troy ounces of silver for each cast, but much of that will be reusable on subsequent casts (buttons and sprues are reusable). Students need only to keep the castings they want. Students are recommended to bring their own eye protection and face mask. Optivisors are handy for waxes.
Lab Fee: US$80
Estimated Materials Cost: US$0-100
