Ramona, I work with nickel-silver (as well as brass and copper).
Nickel-silver is intrinsically stiffer than brass or copper, but
usually that only means that one must anneal more often, when forging
or bending. A customer wore one of my soldered-and-forged
nickel-silver bangles with several of her sterling bangles, 24/7, and
the nickel-silver developed the same lovely shine as the sterling.
Usually, I recommend oxidizing the final product, so that it is not
likely to leave a green (or other) mark on the skin. I’ve never had
any complaints about nickel allergies (perhaps since most folks know
their allergies before they buy).
Try it; you’ll like it! It’s fun to experiment with. I understand
that nickel-silver reticulates very nicely – it’s another thing I
mean to try someday. Go to the Orchid Archives and see what other
may be there.
All the best,
Owego, NY (down along the Susquehanna River, which fortunately has
not flooded this year)
