I have made a brass, copper and sterling bracelet.. What, if
anything, can I lacquer it with so it all does not discolor on the
winning bidder...I would like it and its finishes to last for as
long as possible without turning an awful color.
Laurie, I work with brass and copper and would not lacquer anything
but a wall-hanging. I suggest that you oxidize (patinate) the
bracelet instead (the base metal will turn black; rub off the excess
with a thick mix of water and pumice). This will give any recesses in
the design nice black shadows, and a slight amount of darkness left
on the inside of the bracelet will prevent/retard the skin on the
wearer's arm turning green. The only care it will need after that is
an occasional rub with a silver-polishing cloth (a note to that
effect could be included with the bracelet), which it would need even
if the bracelet were all silver.
Lacquer on objects like jewelry eventually wears off and leaves
patchy places. To restore the original finish would mean getting off
the rest of the old lacquer and re-lacquering -- tedious processes!
All the best,
