Hi all, I am trying to alloy a batch of 14k yellow gold easy and
hard solder. I and was wondering if anyone has an alloy formula
that works well. I purchased (many years ago) a couple of ounces
of solder alloys that worked well; but, it seems no one sells
just the alloys anymore - and I ran out. I do alot of my own
refining and have very little $$$ invested in my pure gold
(scraps and trade ins, etc.) and want to use some for making
solder with. I found this formula in a book and tried a small
batch. The problem was; it didnt flow at 1389F…It was closer to
1600F; which is about the same melting temp as my gold.

The solder melted fine, but it seemed very “sticky” and wouldnt
flow well. Does anyone have any suggestions? Thanks in advance,
