Will, why not use etching with ferric nitrate?
Hello Katherine, Thank you for your suggestion, but I don't etch. I
think I'm going to use a rolling mill for it. I'm sure that etching
makes complete sense, but I am a foreigner with an accent over here
and, given the climate of paranoia, I feel that people are reluctant
to sell acids to me. Maybe they think I'm going to blow up a plane,
I've no idea. I think it's all very silly, because if I really
wanted to poison the entire population of Pittsburgh, they would all
be death by now. A while ago, I saw something that was 98 % ferric
nitrate at Radio Shack. I think it is used by people who work with
computers to destroy copper components in chips or electronic boards.
I didn't buy it because I wasn't sure it would work on silver. If it
would work, I would try it. Btw, they sell a set of needle files at
Radio Shack (5 files for $ 6.99), which are excellent to use on wax.
With best regards, Will
