High-quality material: Made of high-density fine-grained graphite, 99.9% graphite. More suitable for refining than silicon carbide graphite crucible. Easy to get metal ingots: After turning the graphite ingot mold upside down and tapping the ground lightly, the metal ingot be released from the mold and the metal not stick to the mold itself. Widely applications: molds can be used for experiments and smelting of gold, silver, aluminum, copper and other non-ferrous metals. Excellent characteristics: good thermal conductivity, acid and resistance, resistance. size: 10 x 5 x 2.5 cm Material: graphite colour: Black Package Contents: 2 x gold ingot Mold Only the above package content, other products are not included.
