C-50 Graphite Casting Crucible for J-5

Created using isostatic pressure, a process that makes the crucible significantly more dense and therefore less absorptive, this crucible is ideal for working with white gold and high-karat yellow gold (18-karat and higher). The denser graphite stands up better to their solvent characteristics to deliver a longer service life when used with these metals. Graphite crucibles help scavenge any remaining oxygen from your melt, reducing oxidation of the metal and delivering cleaner pours and finer after-cast surfaces. Use crucibles with 9.5mm pour holes for sprue sizes up to 3/8".
