The term “Hot Glass” refers to blown glass. Blown glass is made from silica (sand) and soda ash. It is heated in furnaces, above 2300F, to the molten state. The molten glass is then gathered onto a rod or blow pipe where it is fashioned into the desired shape. It is during the molten stage that the coloured glass is added in the form of chips or powders.
The finished piece is placed into a Lehr, or cooling oven, to slowly cool over a 12 hour period. The final process is the cold working techniques such as polishing and sandblasting.
