Electrotyping

Electrotype with mold, cast and model

This is an electrotype cast made from a ceramic model of the face of Buddha. The model is a Raku fired ceramic piece made by my father. I made the mould from general purpose RTV silicone rubber. The inside of the mold was given several coat of copper conductive paint and then placed in an electrolytic tank containing a copper sulphate electrolyte and a copper anode. The electrolytic process ran for 48hrs. at 0.5v and 1.30 amps. The casting is between 1.5 and 2mm thick. The head dress presented a casting problem in that the shape produced an air pocket that prevented the copper plating out. I have reversed the hanging fixture to get around this problem in the next casting.
