I have been asked if it is possible to machine graphite - in order to make a mold for casting glass into - aparently the surface of the set cast glass clouds less if it is molded into graphite rather than plaster.
Does anybody have any idea what this involves - is graphite readily available? do people cut pure graphite or is it a compund - does it need cooling fluid, etc..
the question is just speculative so nobody please bust a gut... just finding out if anyone else has done anything similar.
