2pcs Crucibles for Melting Metal - 2.5kg/88oz Graphite Furnace Casting Melting Tool - Casting Refining Aluminum Gold Silver Copper

DescriptionGraphite crucibles for laboratory use, complemented by a quartz melting dishes pot, form a dual protection structure. This melting furnace kit prevents heat injury and equipment damage, meeting user demands for frequent use and enhanced safety during precious metal refining. Specifically, the casting jewelry tools' interior supports consistent, even melting, making it ideal for small-batch production and recovery.Features-Color:Assorted Color-Material:Graphite, Quartz-Size(Graphite crucible (height * top diameter * bottom diameter）):12.50X6.50X5.70cm/4.92X2.56X2.24in-Size(Internal dimensions of graphite crucible):11.50X4.30X4.30cm/4.53X1.69X1.69in-Size(Quartz casing (height * top diameter * bottom diameter)):12.80X8.30X7.40cm/5.04X3.27X2.91in-Size(Quartz jacket inner dimensions):11.80X6.30X6.30cm/4.65X2.48X2.48in- Metal Refining: The thick 5kg crucible for melting metal kit lets you optimize batch size, addressing repeated smelting for copper metal melting pot and jewelry melting pot refinements-Heat Radiation: Quartz outer foundry cup encases the graphite crucible, offering doublelayer protection for furnace crucible setups and safeguarding surrounding equipment in work environments-Precision Engineered Interior: The graphite crucible for casting is for gold, silver, and copper, enhancing melt uniformity and reducing residue, ideal for jewelry crucible casting and laboratory analysis-Reliable Thermal Stability: The stonematched quartz sleeve over the graphite crucible cup resists cracks from sudden temperature shifts, beneficial for small melting crucible frequent use scenarios-PlugandPlay Compatibility: This melting crucible set includes prematched parts, requiring no extra fitment and ensuring smooth operation with smelting pot for copper and melting furnace crucible systems
