Glory hole furnaces are a type of hot flame glass furnace used by glass blowers, glass fusing kiln workers and bead makers to manipulate and shape heated glass.
Normally used by glass blowers the use of these furnaces has now expanded to include other aspects of glassworking.
In its simplest form, a glory hole is a cylinder containing a hot fan forced flame, which is used to heat glass for manipulation and shaping. The glass is usually attached to a metal rod or glass blowing pipe held by the glass artist.
Apart from the large industrial style glory hole furnace there are some tabletop models on the market. These models consist of a cylinder lined with a refractory material and mounted on a steel stand.
