Hi,
I want to make wax copies of an existing stainless fairly-easily-mouldable object (approx two cones with the points facing in, which seperate on the line of thinnest contact), with very good dimensional reproduction (for later lost wax electroforming).
I've done it before, but results weren't very good.
Thinking of using high-stearin candle wax. poured into a water-soluble or otherwise removable transfer mould - I don't mind if the transfer mould is destroyed in the process.
My question is, what would be a suitable mould material? I thought of RTV with a plaster outside, but does anyone have any water-soluble or other suggestions?
Ta,
