A few years ago Chemtane became available, which (as I understand it)
is a “synthetic” version of propane. Glassworkers like it because it
burns much cleaner than propane and the glass isn’t as susceptible to
discoloration from reduction. An oxy/propane burner or torch can be
used with it. However, I was told by my propane company that welders
have had problems with it because it doesn’t have enough carbon, i.e.
too much oxidation.
Does anyone have experience using chemtane instead of propane with an
oxy/propane torch? I don’t want to switch over to it for my glasswork
unless I can also use it for jewelry. Thanks for your advice -
