'purchased' electrolytes dont provide consistent results.
They have told me that they find electroforming is easy for pure
copper, do-able for 999 silver but, in practice, not tenable for
even 24k gold in any meaningful production volumes and certainly
doesnt work for alloys (eg lower carat gold or even 925 silver).
They say that electroforming is very expensive and it is almost

Have a look for yourself and maybe give them a call if you are so
