Twisting together heavy gauge wires of different hardnesses
I have a ring design that I normally do in Argentium that is
basically two 14g wires twisted together, fused and hammered to form
the shank, then separating at the shoulders to make 4 ends with one
on each side coming around to meet the other and form the rest of
the circle while the other 2 curve around to surround a center
stone. Now I have a customer (a good friend actually) who wants the
design done with Argentium and 18k gold and a very nice Australian
parti-colored sapphire. So my concern is this: the difference in
hardness between the two metals is quite a lotand I’m worried that
attempting to twist 14g Argentium and 18k wire will result in just
wrapping the softer Argentium around the much harder gold. I’ve
thought about heat hardening the Argentium and annealling the 18k
first to make them closer in hardness but I’m not sure if that’s
going to work very well. Do any of you have experience twisting
heavy gauge wires of different hardness?
Is there a trick I should know about?
Thank you for your help. May we all never stop learning.
