In this class students will be lead by a professional prop maker, and metal smith, in the in the process of lost wax/ ceramic shell casting. Students will learn the process of making a wax positive, then the steps necessary to create a ceramic silica mold capable of resisting extreme temperatures while maintaining the ability to pick up extreme detail! Students will learn wax burn out procedures, dipping molds in ceramic, casting bronze, and de-molding. On day one items to be cast in bronze will be created in wax, vented, and dipped several times in a ceramic slurry mixture to build up the necessary thickness required. (The following week will be available to students during normal open hours to complete dipping if not completed during class) On day two students will assist in burning out the wax in preparation of pouring bronze later that evening. This technique is widely used in industry and individuals with the knowledge and skill set are highly sought in the work force.
Note: Though it is not required, this class strongly suggests the 101 mold-making course before attempting this class to build off of previously learned skills and to expedite workflow. It is recommended that the piece to be cast in metal has been previously made or cast in wax and this can be accomplished within the previous mold making class.
Work involved – building a flask “container”, mixing two part compounds, adding release agents, unmolding
Tools/Materials Utilized- Mold release spray, razor blades, venting red wax, rubber molds. 5 kg of silicon bronze per student, casting furnace, 10 kg graphite crucible for bronze. Borax flux, skimmer, heat resistant safety gear, ceramic slurry, various grits of silica sand, zircon, burn out oven, large metal tray, modeling brown wax, electric eye burner, propane burner, sculpting wax tools, soldering iron, pots, figurine, crucible shank, safety equipment
