hi betty. I work a lot in hi-karat gold… when fusing 22k, do NOT
use flux - heat with a bushy flame. the most important thing is to
be sure the edges of the bezel abut really well. we file the edges
to obtain a really good contact, then heat slowly with a 0 tip, bushy
flame. we use the oxy-acetylene torches.
a lot of people use a charcoal block - I prefer the white soldering
boards. either one is fine!
don’t be intimidated. gold is far more forgiving than silver, and I
think it’s considerably easier to work with…!
if you live anywhere near NY there’s a great school for classical
jewelry – fusing and granulation techniques, the way the greeks &
romans used to do it… Celia Bauer studios. actually you don’t even
have to live near NY to take classes there, a lot of people come from
all over the country - there are week-long summer intensives… great
place to really master fusing & granulation.
