Cheers.
Haha, I just spent ages reading about mixing it with alcohol and using it as a barrier flux and came to ask about that and noticed I should have just read on.
With the flux I use for silver (Johnson Matthey Easyflo) I read somewhere to add a drop or two of washing up liquid so that if it dries out you can add a bit of water and re-paste it. The thing I read said that without the washing up liquid it’d dry rock hard and not dissolve again.
Thoughts? Would you do the same with the boric acid or unnecessary?
I actually keep some Easyflo mixed in a jam jar, the lid probably stops it drying out enough that the washing up liquid isn’t needed.

I just use boric acid off ebay for brass. Dirt cheap and works fine. Your silver flux will cook before you get up to temp so you will need something different either way.
