Subject: application of graphite to non conductive materials.
From: Patrick Storme

We have experience with electroforming techniques on different materials.
In most cases we make reproductions in negative silicone moulds, were we
brush in very fine silver, copper or graphite powder to make it conductive.
For other materials, which will not hold the powder, we use sprays with pure
copper or graphite.
I hope to be of some help.
Yours sincerely,
Patrick Storme.
