What is Electroforming?
If you’re asking me, it is part science and part magic!
Particles of copper are taken from a source or donor piece of copper, known as the anode, and deposited onto a recipient target, called a cathode.
This is done using a controlled electrical current generated by a device known as a rectifier in a highly acidic copper sulphate solution.
It is much like electroplating, although with electroFORMING,the surface is non metallic and therefore must be prepared beforehand to be electrically conductive with a copper or graphite based coating.
This is my tank:
It can handle 10-12 rings at a time. The entire process takes a few days and the results are somewhat unpredictable, but it is incredibly satisfying to pull a piece out of the bath!
I like using this technique for large gemstones, points and chips. The texture and organic feel of the copper really suits raw, rough crystals.
I then clean the pieces, file any rough or sharp edges, oxidize, and buff/polish.
