Glass Casting is the process in which glass objects are cast by directing molten glass into a mould where it solidifies. The technique has been used since the Egyptian period. Modern cast glass is formed by a variety of processes such as fusing and kilncasting, or casting into sand, graphite or metal moulds.
- Direct Casting/Hot Casting - Pouring fully molten glass into a mould, usually from a furnace.
- Billet Casting - Melting glass billet into a kiln washed mold and heating in a kiln until the glass flows and fills the mould. Once filled the glass is soaked and annealed to cool over the course of days.
- Lost Wax Casting - A pattern is made from wax and a refractory mould is formed around that wax. The wax is then melted out of the cavity and the cavity is filled with molten glass and annealed inside of a kiln.
- Fused Sheet - Large slabs can be achieved with an even bubble pattern thru the process of fusing sheets together in a kiln. Sheets are stacked and fired until they have merged into one slab.
