• (2) 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 that is often used in melting and refining metals as it aids in lowering the melting points of different minerals so your material melts quicker and is easier to pour. Add it to your melt to help draw out impurities or "slag" for cleaner and more pure material. It acts as cleaning agent, minimizes gold loss in your slag, and helps keep your material liquefied longer. Keeps your metals cleaner during melts and pours and 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.
• (1) 6 Cavity - 1/4, 1/2, 1 Troy Ounce Gold Multi-Cavity Combo High-Density Graphite Ingot Mold: Designed with a smooth cavity finish, with ten degree tapered sides for easy ingot removal. Typically lasts for 30+ pours.
