High Back CruciblesA to Z Jewelry Tools & Supplies
Made in Italy of ceramic and fused silica, High Back Crucibles can withstand temperatures up to 2,800°F and are used to melt metals like gold, silver, and alloys when casting. The high back on these help ease melting with torches and also with pouring melted metals when ready to cast.
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 holders for safety.
