Hydrogen? Talk about living on the edge....
I thought the hydrogen fueled flame was close to invisible. ??
If used, Hydrogen would be a flow ratio of two to one of Oxygen. Since
end product becomes H2O. I'm guessing the pressure would be similar to
propane gas, about 5-15 PSI.
Most people I know use propane gas because it 1) can be
supplied/provided at higher pressure than natural gas (without a
pressure booster) and 2) has higher BTU content than Natural gas 3) is
relatively cheap and easy to obtain (not sure what H2 bottles charge for
refills)
Last I checked, my minor torch was designed for propane.
MINOR BURNER by Nortel
The standard for soft glass beadmakers and small borosilicate work. The
Minor Burner is a surface mix torch and is therefore as quiet as a
whisper. It can be adjusted to a reduction, neutral or oxidation flame
each of which affects soft glass colors differently. Use with propane or
natural gas and oxygen.
Help: What are the pros/cons on using hydrogen as a fuel? (dated March
2001)
From: http://www.lampworkers.com/bbs/index.cgi?noframes;read=7385
The pros are it burns way hotter and way cleaner than nat. gas or
propane. Making the glass work faster takes time to get used to.
The cons: It's *extremely* flammable! You may have problems (zoning,
fire dept., safety inspectors, etc.). It's also expensive, it costs a
little more than oxy but burns way faster like 2 or 3:1.
What type of work are you doing? I wouldn't recommend it unless you are
doing (a lot) of really big lathe work. Otherwise it won't pay for itself.
Oh yeah be real careful working color w/ it. It will *all* end up clear
otherwise!
Here's another site that discusses various fuels and their uses.

Hydrogen can produce flame hot enough for melting platinum...so I guess
the better question is "whatcha making??"
Warm regards? That can be blazing HOT! ;-)
