Weekend workshops in the use of plaster silica molds to kiln cast glass sculptures of clay models

  • California Avenue

Service Description

Over the course of 3 weekends, students will complete an individual cast glass sculpture project using clay, glass, refractory and found objects. Participants will learn to: 1. Design - an open faced cast sculpture that will avoid the most common problems 2. Sculpt - simple sculptures using a mix of hand sculpting techniques in clay, combined with found objects 3. Mold Making - create refractory molds suitable for glass casting in kilns 4. Cast - pack your molds with glass and use an appropriate firing schedule to cast your work. 5. Finishing - use MGW's cold working studio to finish your works (cutting, grinding, sand blasting, etc) and discuss / choose among final display options (wall mounted, stand mounted, etc). PREREQUISITES The goal of this workshop is to help glass artists expand their repertoire of techniques they can use in their own studio work and to allow artists from other sculptural mediums understand how they might incorporate glass into their work. The ideal participant would already have some fluency in using kilns to make glass art, such as our introduction to kiln forming class. But prior experience is not strictly mandatory. MATERIALS All consumable materials (clay, plaster, silica, release agents, etc) and sculpting tools will be provided by the studio, but participants are welcome to bring their own clay and tools if they have preference. - Found objects: Prior to the beginning of class, participants will receive a curriculum PDF which describes the worksteps we'll complete during the course. Participants will want to bring a few options that would fit within a roughly 6" x 6" size (eg shells, plant parts, tools, jewelry, 3d printed objects, etc.). Artists that wish to sculpt their forms without found objects are welcome to do so. - Clear Glass is provided as part of this class in suitable quantities to complete your class projects. - Colored Glass: We will discuss colored glass design choices of which there are many. We recommend and use bullseye glass (COE 90) transparents. You are welcome to bring your own glass to cast, but it will need to be 90COE if you wish to intermix with our studio clear casting glass. You will need roughly 2kg of frit, powder or casting billet to complete the class project, more if you wish to work larger than 6" x 6". We are happy to provide bulk packs in mixed colors suitable to complete the project with a bit left over for future work. Find bulk casting packs in our 'Shop the Studio'.
