I'm not likely ever to encounter gold wire in my soldering experiences.

Try it with some copper water tubing that was a bit overheated when the
original joint was made, and almost everyone is surprised. It can be a

to pull apart; it squeeks from the friction of the hard intermetallics;

it just may freeze up on you and refuse to come apart until you nearly
melt
the parent metal.

Hey thanks Ed! I've experienced that effect with copper plumbing fittings
many
times, but never learned what caused it.

One thing that can help is to start putting tension on the joint as you heat
it. Just when it passes the melting point of the solder, it's most likely to
come apart without trouble. Work fast.
