Call me stupid (you won't be the first)...why do you want to use sal =
ammoniac=20
in flux?  What's the supposed advantage, how does it help, etc?  =
Honestly=20
don't know...I'm happy with the borax/boric acid mix.

	Sal ammoniac is a tinning agent.  Borax is a high temperature flux and =
melts at too high a temperature to be any use in soft soldering.  Sal =
ammoniac does what any flux does: it cleans the surface of certain =
classes of impurities, only at a lowe temperature and hence works well =
for low temperature solders.  AFAIK, it is used mainly for tinning =
soldering coppers.  I believe it can also be used as a soldering flux, =
but I found other fluxes work a little better; not that I do a whole lot =
of soft soldering.
