Glass Casting

The glass molds are made of resin, silica sand and a catalyst. When mixed together, the material hardens to a sandstone-like consistency. Designs are then carved into the mold using hand tools, air tools and a number of improvised gadgets that help to create a desired texture or depth. The carvings are executed in a free hand, sculptural fashion with none of the restrictions typically imposed by positives or multi-part molds. Undercuts present no problem and intricate, finely detailed pieces are attainable. Molten glass is then poured into the mold and the glass picks up the most delicate of textures along with the deepest cuts to display imagery in very high relief. During the final process the high temperatures destroy the mold, making each piece unique

The glass provides a solid, very durable structure with the added advantage of passing over 95% of the light that strikes it. The deep relief of the designs invites hands on interaction and a wonderful surface that plays with the light. While glass is often thought of as "breakable", this glass, due to its thickness, is a strong structural element.
