The basics are the same…heat all the surrounding area and then
concentrate on the joint area until the solder flows.
Gold alloys do not conduct heat as fast as silver does, so less
surrounding area needs to be heated.
9ct Gold alloy will melt at red hot. 9ct Hard solder melts just
before or at red hot.
18ct Gold alloys are stable at red hot, and 18ct hard solder must be
red hot before it melts.
Practise by soldering the ends of some bars or wires of your chosen
alloy together. For good measure, try to re-melt the solder after a
successful soldering. Re-melting the solder should reveal a very
useful phenomena…it requires a lot more heat to re-melt. Using
hard solder, you can make successive joins and with care the
previous joins will not melt while melting new hard solder.
Go straight to hard gold solders. Don’t mess with ‘easy’ or
’extra-easy’. These are messy and a hinderance to learning. 'Medium’
is very usefull, but the ‘easy’ solders must be reserved only for
Dive in, do some trial solderings, and gold will be yours no
