Ms. Nomers, the first installment

In a continuing quest to get incorrect words and phrases out of normal usage, this series of articles will try to present the proper terminology for glassworkers to use.

Single fuel/dual fuel torches is one of my all time favorites.

Fuel/air torch, of which the Hot Head is an example. These are sometimes called “single fuel” torches, but this is a misnomer. The torch is actually a fuel/air torch where fuel gas, such as propane is mixed with room air before ignition.

Fuel/oxygen torch, of which the Minor is an example. These are sometimes called “dual fuel” torches, but this is a misnomer. The torch is actually a fuel/oxygen torch, where fuel gas, such as propane is mixed with oxygen either before ignition (pre-mix type torch), or at the surface of the torch face after ignition (surface mix type torch).

We don’t know where single fuel/dual fuel torches got started, but to call them that is incorrect. All lampworking torches ARE in fact, single fuel torches.
