February 10, 20188 yr Author I looked everywhere and could not find the ingredients, how do you know it's just Borax? It looks like Larry started formulating it 10 years ago.
February 10, 20188 yr Ask for the Saftey Data Sheet to find out what's in it. Some of the commercially available fluxes claim to have no borax in them.
February 11, 20188 yr You don't have to ask, it's available online. 99% Sodium Tetraborate....aka borax.
February 11, 20188 yr If you go to the torch welding, brazing, silver soldering, etc. isle in your local welding supplier's place start reading labels on cans of dry flux. Most are anhydrous borax, boric acid and some proprietary thing to color it, quite a few have iron powder in them too if you like. I bught a can of Patterson's Blue ( forget if it's #1 or #2) it's the one without iron in it. It was $23.76 IIRC for a 1 lb. can shipping included. A can of E weld, Cherry weld, Swan, etc. starts around $90/lb. + shipping. The Patterson's blue works just fine. Better than laundry borax, it forms an even continuous cover without boiling. That's a property of being anhydrous, no water can't boil. Frosty The Lucky.
