• (6) 1.5" x 1.75" Graphite Crucible Cups: Melts up to 6 oz gold, or up to 3 oz silver or copper can be melted at once.
• (1) Pair of 12-1/2" Beaker Flask Crucible Tongs: Specifically designed to securely hold your crucibles with one hand; easily grasps your crucible with its grooved end.
• (1) 3 oz Package of Anhydrous Borax: A multi-purpose, high-grade and course casting flux often used in melting and refining metals; it aids in lowering melting points of different minerals so your material melts quicker and is easier to pour. Helps draw out impurities or "slag" for cleaner and more pure material, acts as cleaning agent, minimizes gold loss in your slag, and helps keep your material liquefied longer. Also great for seasoning graphite crucibles. Draws out gasses and oxides out of molten metal, such as gold, silver, copper, iron, sterling silver, tin, nickel, and their alloys. Made in the USA.
