C-20 Graphite Alloying Crucible for GrainPro Hydraulic Forming Already cut from sheet intoThis economical C 20 graphite crucible is created from an extruded graphite material that's well suited to working with silver, lower karat yellow gold (14 karat or less), brass, bronze and other copper based alloys. For white gold or higher karat yellow gold, choose a crucible made from denser C 50 graphite. Graphite crucibles help scavenge any remaining oxygen from your melt, reducing oxidation of the metal and delivering cleaner alloy and grain.
