Hi, I’ve been having trouble getting even easy 18kt gold solder to
flow on large pieces such as pendants and rings. I’ve been
soldering for over twenty years and on sterling and more delicate
gold pieces with no problem. On these larger pieces the gold looks
ready to melt and the solder doesn’t flow.easily, no matter how
clean, well fitted ,or fluxed. Has anyone else experienced this
problem and can offer any tips.
