• High performance: This quartz melting crucible cup can be used within 1900°C. It has high purity, high strength, not easy to deform, and is durable. Note: To avoid gold, silver and other metals from sticking to the bottom when melted, place borax at the bottom of the bowl when using. And please preheat to 250 degrees before use and then gradually heat to avoid bursting caused by heating up too quickly
• Wide application: Ceramic melting crucible plate cup, universal compatibility with gold, silver and high-temperature alloy smelting applications, widely used in electric lighting, semiconductor, metallurgy, building materials, industry, machinery and other fields
• Good thermal conductivity: Ceramic quartz crucible has good thermal conductivity and maintains structural integrity during precious metal refining, helping you shorten melting time and save time and energy
• Durable material: The smelting crucible cup is made of quartz material, which is strong and durable with good thermal conductivity. Precision ceramic processing ensures uniform wall thickness and ensures even heating
• Package includes: 1* crucible cup with matching lid for immediate use
