Orchidians: I could use a little advice on soldering gold. I have
worked with silver for a few years and am now trying to learn to work
with 18Kt and 22Kt yellow gold. Unfortunately, most of my attampts to
solder end up melting the gold instead.
For example, after I used my hydraulic press on an annealed sheet of
30 gauge, 18Kt yellow gold, I noticed some cracks. I annealed the
metal and worked the cracks closed. Then I fluxed the sheet, set a
few pallions of 18Kt medium solder on to the cracks. I put a No. 4 tip
in my Little Torch. I set the Acet/Oxy mix to a neutral flame. But
despite my best fforts to use a light touch with the flame, the gold
sheet turned red and melted. The solder never ran. Can anyone give me
a few pointers as to what I’m doing wrong? Thanks.
