Any coating will eventual come or wear off, including plating.
That's what I thought...
The raw metal will turn the skin funny colors. It will corrode in
contact with dissimilar metals. This is the nature of the beast.
Yes... not good for crocheted necklaces or bracelets... but maybe
longer-lasting when used for pendants or brooches?
Does it tend to corrode when in contact with "red brass" (90%
copper, 10% zinc) or lead-free pewter (92% tin, 7.5% antimony, 0.5%
copper)? (I'm sensitive to nickel, want to try using pewter as a
white base metal to practice on instead, found a manufacturer of
pewter sheet and wire 0.8 mm. [about 20-gauge] and thicker.)
I have a design idea for fabricating a pendant/pin that would
involve one sheet each of copper, brass, and pewter. I would pierce
different parts of a pattern into each of two of the sheets, then
rivet them to a base of the third sheet. I think this would give me
good practice piercing, sawing, filing, and finishing. Trying to
solder copper, brass, and pewter together sounds impractical, hence
the attempt to fabricate a cold connection. Not sure if riveting
three sheets together is a good way to start, maybe I should think
about cutting the base sheet to include tabs to fold up over the
other two, and work them into the design somehow. I don't like to
copy other people's projects, even for practicing, but sometimes end
up frustrated because my own design ideas don't work out with the
materials I've chosen. I'm thinking that the pewter will be the
softest metal, so it should either be used for the middle layer,
where it will be most protected (if I use tabs), or maybe the bottom
layer, if I use rivets, so that any scratches that happen after the
piece leaves my hands will most likely be on the back of the piece.
If the piece is really experimental, I work out my ideas in copper
first then reproduce them in gold or silver.
I am basically practicing with copper before working with silver
(hopefully gold will be somewhere in my future).
Every metal has its characteristics and limits. The fun is in
learning how far you can go before hitting those limitations. The
key: learn the nature of your materials. I love seeing what I can
get away with once I know what I can't get away with. Usually much
more than one thinks possible.
I'm happy that you're emphasizing that it can be fun! I am feeling
anxious, keep reminding myself that even base metal mistakes can be
sent back to the supplier for refining and re-use instead of tossed
into a landfill.
I was blown away by these photos of fold-forming that I found while
which seems to work beautifully in copper. Have you tried this
