[TheForge] Drying Borax (was: Welding flux?)

[Peter Fels & Phoebe Palmer]

Hey Jerry
Email Peterson's and ask..
Or, if they have an 800 number, see if you can talk your way back to the tech guys
Or, call sales and see if they will send you a sample to test in the name of your whole darn BS assn.
You can convincingly ad lib the argument.

True Pete but the battered blender's already bodaciously, badly, beat. Now, I suppose a planishing bit in my air hammer'd work. AND I might have to give it a shot if nobody here stops talking about drying borax and tells me how Patterson #2 HT flux works for a forge weld. <hint hint>

Borax being water soluable and hydrophilic changes from a water holding solid to a dissolved state at heat and sets up like cement when it dries or cools. Yeah, that's intuitive speculation but it fits what I've observed. The trick would be driving off the water at a gradual enough rate it doesn't form steam to dissolve the borax. Basically I THINK the borax is turning into hot mud when it foams rather than melting and sets like concrete when it cools or dries. The cooled foam isn't easy to grind at all. the best method I've seen used is to sprinkle a thin layer on aluminum foil, heat and when it cools just roll the foil up and crush as you wish. If you make the layer too thick it just tears the foil to shreds when you try to break it up.

Good grief Bruce, if it turns out you and I think alike I'm blaming the TREE. <grin> I LOVE yard/garage/whatever sales I've made some wonderful scores, one of our best was a high quality, say $500 +/- spinning wheel for Deb for $50 and the gal MADE us take about 10 trash bags of processed wool. One of my best recent finds was a needle scaler for $2.00
