I’m on the road at the moment, and was making wire for a project
when I realized that I had no boric acid handy. I normally coat my
wire in that to prevent scale, so I was pretty bummed out that I’d
forgotten to bring it with me.
Looked at the flux (the green stuff from Rio) and thought, “Hey, why
not?” I diluted some of it in some water and soaked the coil (18K
yellow wire) in it, then annealed it. No scale.
So… is there any reason not to do this? Been using boric acid in
alcohol for years, because that’s what I was taught, but this seems
pretty effective, maybe even more so.
