Ceramic Crucible 3KG Large Capacity for Melting Furnace Casting Machine 1350℃ High Temperature Resistant Gold Silver Smelting Commercial Jewelry Production

Long Description 3KG Crucible – For Jewelry Workshops That Think in Batches, Not Pieces If you are still melting in 1KG or 2KG crucibles but running five or six melts per day, you are leaving money on the table. Every melt cycle costs fuel, time, and crucible wear. The 3KG crucible cuts your cycles by half or more. Real Workshop Scenario A commercial jewelry studio processes 4-5KG of scrap gold per day, plus fresh alloy for new production. Before: 5-6 separate melts. After: 2 melts with 3KG crucibles. The owner saves over an hour daily – time that goes into finishing and shipping. Built for High Frequency This is not a hobby crucible. The dense ceramic structure is engineered for sustained high-temperature operation and rapid thermal cycling. Pour one flask, return the crucible to the furnace, add more metal, melt again. Production workflow without waiting. Check Your Furnace First Dimensions: Bottom 5.7cm | Height 15.8cm | Outer top 7.1cm | Inner 5.0cm | Rim 1.9cm | Net 380g Measure your furnace chamber before ordering. This crucible fits most compact commercial jewelry melting furnaces but is taller than standard 1KG units. Package 1 x 3KG Ceramic Crucible (1350℃ rated)

• Melt Once, Cast All Day – 3KG capacity handles entire daily production for many small workshops. Load your morning scrap, melt once, pour multiple flasks or ingots continuously.
• Designed for Back-to-Back Melts – Thicker wall construction resists thermal fatigue from continuous use. Run melt after melt without waiting for crucible to cool or worrying about cracking.
• Fewer Cycles = Lower Operating Cost – Three 1KG melts take triple the fuel and triple the time. One 3KG melt saves energy and labor hours. Simple math for production shops.
• Still Fits Standard Jewelry Furnaces – Bottom 5.7cm, height 15.8cm, outer top 7.1cm, inner 5cm, net weight 380g. Taller and slightly wider, but designed for compact commercial furnaces.
• Production-Grade Durability – Natural light yellowish color is normal. Acid/alkali resistant surface stands up to aggressive fluxes used in scrap refining and alloy preparation.
