Electroforming 3

Decided to give the practical aspect of this project a rest for a while.

I have been doing some reading from the excellent “Jewellery Concepts and Technology” by Oppi Untracht (Robert Hale, London, 1982), particularly Chapter 16 “Metallic Buildup – Electrolytic Molecular Creation of Surface and Form”.

It’s got about 40 pages of detailed info about all aspects of electroforming and electroplating, including this recipe:

Typical Acid Copper Plating Bath

  • Copper Sulphate (26-33 ounces per gallon)
  • Sulphuric Acid (4-10 ounces per gallon)
  • Current Density (20-40 amps/square foot)
  • Voltage (6)
  • Temperature (21-48 centigrade)
  • Anode (copper)

Experiment to be continued in November!
