Basic principles: Crucible
Always use crucible and inserts for the same alloy.
Crucibles can be marked with a pencil.
WARNINGS
Burn hazard from hot parts!
• Always wear protective gloves
when touching the crucible handles.
• Always use mould tongs to move
crucible inserts!
NOTE
Recommendation: Only use BEGO crucibles
(identifiable by the BEGO logo)! Crucibles of
other manufacturers frequently have the wrong
dimensions. This will result in faulty casts when
the crucible opens too late or if the melt flows out
of the crucible too soon.
Screw the handles tightly onto the crucible.
WARNINGS
When using inserts, the handles
become extremely hot: plastic
handles would melt!
Inserts (made of graphite or glassy
carbon) require ceramic handles!
NOTE
Graphite inserts are subject to wear and must be
replaced in good time! Used inserts can be
identified by their weight (
graphite ~6 g, glassy
carbon ~5 g
) and also by the fact that the
increase in temperature during the melting
process slows down from one casting process to
the next. The casting temperature can no longer
be attained with worn graphite inserts!
