Feature

●Composition: 99.95% graphite. Ash is less than 0.1%. Excellent thermal conductivity and corrosion resistance The stone ink is more suitable for refined than silicon carbide graphite
●[Performance] Excellent thermal stability for fast heating and cooling; Corrosion resistance to strong acids and alkalis; significantly reduces melting time and has excellent thermal conductivity properties to save energy; Excellent impact resistance ensures product quality reliability
●【Tip】Pure graphite urns cannot be heated with carbon or charcoal furnaces. It will oxidize and crack. Pure graphite starts to oxidize at 752°F (400°C). When using an air electric furnace, it can withstand temperatures up to 3200°F. When using a vacuum or gas furnace, it can withstand temperatures of 5000°F
●[Uses] Melting and casting gold, silver, brass, aluminum, copper, zinc, lead, etc
●Package: 1 x Square Stone Ink Well packaged to ensure the safe delivery of the item
