Included in the warm glass techniques are fusing and casting. In fusing, layers of glass are heated (usually to about 1450º) until they melt together. They are cooled slowly, in a process called annealing. In casting, bits of glass, ranging in size from a fine powder to large chunks, are melted together in a mold, and again annealed.
Sounds simple enough, doesn't it? Glass artists have taken this simple process and found endless variations. After two pieces of glass are fused together, the artist may choose to add details made of "frit" (ground glass), stringers (spaghetti-sized rods of glass), enamel paints, metals & more. They can them "slump" the glass in a mold to shape it into a bowl, vase, a mask, a sconce and many other items.
In casting, bits of glass placed in molds may become tiny pendants or large sculptures. In the photo above, Emily Brock created a glass studio made of cast glass items. This amazing piece is only about 15" x 15" and is made entirely of glass. Her work was recently on display at the Museum of Fine Arts, in Saint Petersburg, Florida.
I work with both fusing and casting. Visit my shop on Etsy to see more.
