|Torch: ||A reducing glass that can develop a metallic sheen. In some cases, this metallic sheen is transparent enough to see through it to the green glass. Start by working 1707 in a neutral flame. When you are ready to develop a metallic sheen, the glass should be relatively cool (no visible heat) and stable on the mandrel. |
Create a reduction atmosphere by turning the propane (fuel) up and while passing the bead through the flame, watch for the surface of the glass to become metallic. Once this has happened, the piece should be put into an annealing kiln. This is a finishing step. If the metallic surface is reintroduced to a neutral flame, it will dissipate. It can be brought out again by returning it to a reduction atmosphere.
When molten, this glass has a low viscosity, and can be quite soft, which may result in a blurred edge where it meets other glasses. In addition, the process of reducing the glass can cause a metallic sheen over areas of glass immediately adjacent to this style.
