  • Frit Casting – Placing pieces of frit inside a kiln washed mold and heating until the glass fills the mold. This process can take several firings to accomplish.

  • Hot Casting – Pouring molten glass into a mold, usually from a furnace.

  • Lost Wax Method – This method is sometimes called lost wax casting or lost mold casting. A pattern is first carved out of a wax block and once that is finished a plaster mold is formed around the carved wax. The carved wax is then melted out of the plaster and the cavity is filled with molten glass and annealed inside a kiln.

  • Pate de Verre – Fusing a paste made with tiny pieces of glass inside a mold. The name actually translates to glass paste.
