I guess I am cheap and wondering why not to use borax if it is cheap
and plentiful?
I use boric acid that I buy cheaply from the pharmacy of my grocery
store in the band aid section and methyl alcohol that I order from
Indian Jewelers. Works just as well as any flux I’ve ever bought.
Admittedly, I have some Firescoff that I have yet to open and try but
I hear that is good as well. Most of the flux you buy is just boric
acid and alcohol, I believe. The Handy flux that I have gets dry and
I have to thin it down with alcohol anyway, so what’s the difference?
