Can someone please tell me the proper crucible material to
use with gold? I have looked everywhere and I can't find
a thing! I believe that we are getting carbon contamination
when we evaporate gold from a graphite liner.

Also, I have tried to adjust our beam spot size, but it is
very hard in our system to tell if the beam is striking the
material or the crucible or both. Is it normal for a graphite
crucible to glow orange-hot when evaporating? I am trying
to determine if we are getting contamination from a wrong
crucible material or a badly deformed beam spot.

Thanks
Chris
