Made in Italy of ceramic and fused silica, Melting Cup Crucibles can withstand temperatures up to 2,800°F and are used to melt metals like gold, silver, and alloys when casting because they have good thermal conductivity and won't contaminate metal alloys.

It is recommended that borax be melted into crucibles before first use to create a film that will minimize oxidation when melting.  These crucibles should also be used with crucible tongs for safety.
