Ceramic Crucible 1KG High Temperature Resistant for Melting Furnace Casting Machine Gold Silver Smelting Jewelry Casting Up to 1350℃ Metal Refining Tool

Straight Wall Ceramic Crucible – 1KG Capacity, 1350℃ Heat Resistance for Melting Furnaces & Casting Machines Enhance your metal melting and casting workflow with our professional-grade straight wall ceramic crucible. Specifically engineered for use in melting furnaces and casting machines, this crucible is the reliable choice for jewelers, dental technicians, laboratory professionals, and small foundry operators. Superior High-Temperature Performance Rated for continuous operation up to 1350℃, this crucible easily handles the intense heat required for melting gold, silver, brass, copper, and other non-ferrous metals. Whether you are operating an electric melting furnace, gas furnace, or investment casting machine, this crucible delivers consistent, repeatable results. Straight Wall Design for Professional Equipment Unlike tapered or round-bottom crucibles, the straight cylindrical wall design ensures a secure fit in standard melting furnace chambers and casting machine holders. This geometry promotes even heat distribution around the metal charge and allows for clean, controlled pouring into molds or ingot trays. Built to Last Under Tough Conditions The dense, compact ceramic structure provides outstanding resistance to thermal shock. Transfer the crucible from furnace to casting station without fear of cracking. Its acid and alkali resistance makes it compatible with borax, boric acid, and other common fluxes used in precious metal refining. Precision Dimensions for 1KG Melting Capacity Bottom diameter: 5 cm Total height: 12.4 cm Outer top diameter: 6.5 cm Inner diameter: 3.9 cm Rim height: 1.8 cm Net weight: only 275 g Capacity: approximately 1 kg of molten metal (varies by metal type) Despite its lightweight construction (275g), this crucible offers excellent mechanical strength and durability for repeated high-temperature cycles. Natural Appearance Variation The crucible displays a natural slightly yellowish or off-white color. This is a normal characteristic of this specific high-performance ceramic formulation and does not affect heat resistance, structural density, chemical stability, or melt purity. Ideal Applications Melting furnaces (electric, gas, induction) Vacuum and centrifugal casting machines Gold, silver, platinum melting and refining Jewelry making and repair Dental alloy casting Small-scale foundry and scrap metal recovery Laboratory high-temperature experiments Safe Usage Guidelines Preheat the crucible gradually before full-temperature operation. Always use appropriate crucible tongs, heat-resistant gloves, and safety glasses. Allow the crucible to cool slowly after use to maximize service life. Clean residual flux and slag after each use for best performance. Package Includes 1 x Straight Wall Ceramic Crucible (1KG capacity, 1350℃ rated, for furnace and casting machine use)

• Up to 1350℃ High Temperature Resistance – This straight wall ceramic crucible withstands extreme heat up to 1350℃, specifically designed for use in melting furnaces and casting machines. Ideal for melting gold, silver, copper, and other precious metals for jewelry making and small foundry work.
• Strong Thermal Shock & Corrosion Resistance – Engineered with a dense, compact ceramic structure, this crucible resists sudden temperature changes without cracking. Excellent acid and alkali resistance ensures long-lasting durability during repeated melting, refining, and casting cycles.
• Straight Wall Design for Furnace & Casting Machine Compatibility – The straight cylindrical wall allows for easy placement and removal from standard melting furnaces and casting machines. Provides even heat distribution and smooth metal pouring for professional results.
• 1KG Capacity with Precision Dimensions – Bottom diameter 5cm, overall height 12.4cm, outer top diameter 6.5cm, inner diameter 3.9cm, rim height 1.8cm, net weight 275g. Compact straight wall profile maximizes interior space while fitting securely in most small to medium melting equipment.
• Reliable for Precious Metal Refining & Casting – Perfect for jewelers, metallurgists, and hobbyists. The crucible features a natural slightly off-white (light yellowish) appearance due to its high-performance ceramic composition, which does not affect function, durability, or melt quality.
