can you blow glass with an oxy-acetylene torch?
I have an oxy-acetylene welding torch and was wondering if it can be used to blow boro glass? Anybody used it before?
There are two kinds of glassblowng: at the torch and at the furnace. Torch or flame working includes scientific, neon, and artistic working. It may be done witth soft glass (melts around 1800F) or borosilicate (melts around 2200F). The former requires more careful handling and annealing but until recently the latter had few colors.
While an oxy-acetyl torch can be used to try things out, but it is too hot and too small for real work. The former means that it tends to boil the glass and burn off colors. If you manage to spread it out, it tends to put a dark tone in the glass which looks ugly.
Soft glass torch working on a small scale can be done with a propane or MAPP braising torch (like the Hot Head), but larger pieces and borosilicate are down with oxy-propane torches of which many are available from just over $100 to over $300. Tanks and regulators add several hundred to that.
