January 2019 Glass workshops:
Advance registration is always a good idea when it comes to ordering colour! 😉
Students learn the basics of pâte de verre from start to finish while making a thin-walled, kiln formed bowl. Students have access to a broad palette of coloured frit (crushed glass) and samples to help predict and understand fired qualities. Demonstrations include various techniques of working with glass powders against the mold, working with color reactions, as well as how to back-fill a packed mold to support the walls of the piece during firing.
Size max 18cm in any direction.
Day 1: Replication. Students will make silicone or alginate moulds from items they wish to cast in glass. Examples: plastic/vinyl toy/action figure, anatomical models or small branch, unusual vegetable/fruit, seed pod. Items could also be modelled from Sculpey clay and fired ahead of attending the workshop. Glass options are discussed. While the silicone moulds cure, students build a small bowl form out of clay (add texture/details) and from there build a refractory mould, once set-up the clay is removed and students are shown how to apply glass to the mould a la Pate de Verre. Colour samples are also made on this day.
Day 2: Wax pouring and hand-built moulds. Students pour multiple waxes from their silicone moulds, refine their wax models (add or subtract). Models are then weighed and various glass options are revisited. Once glass choice is determined pouring gates are added to models and then a silica based refractory mould is built around the wax models. Once moulds set up the wax is then steamed out. Meanwhile, glass is weighed, and cleaned. -Items are cast & annealed over the week.
Day 3: De-mould kiln castings/cold working Students remove their kiln cast objects and start the cold working process. Various methods and equipment are discussed and demonstrated.
Day 4: Finish cleaning kiln cast objects.
Lab fee (optional): $100 covers Gaffer crystal colours*, Bullseye colours: sheet, billet or coarse frit, metals, & mould kits. Students are emailed concerning glass colour choice, otherwise everyone works with clear glass and coloured frit.
