High-Temperature Graphite Crucible - 3000℃ Heat Resistant with Handle, Ideal for Jewelry Melting, Gold Refining, and Laboratory Use, 0.9ml Capacity (17g Molten Gold)

Experience the versatility and efficiency of our premium Crucible, designed for a wide range of applications in the precious metals industry. Whether you're casting gold and silver bars or coins, our crucible delivers a smooth surface with distinct edges, ensuring high-quality results every time. For jewelry recycling, enjoy rapid 5-minute smelting of old materials that effectively separates impurities, resulting in excellent fluidity of molten gold. Our crucible is also perfect for laboratory precious metal purification, achieving an impressive 99.99% purity. It is compatible with rare metals like platinum and palladium, making it a reliable choice for research-grade applications. In laboratory analysis, our crucible aids in the purification of semiconductor materials and is suitable for high-temperature reaction vessels, catering to various scientific needs. **Instructions for Use**: - For first-time use, we recommend baking the crucible at a low temperature for 2 hours to activate the antioxidant layer, extending its lifespan by up to 30%. - Preheat gradually at 200℃ for 10 minutes to avoid thermal shock. - During smelting, do not exceed 80% of the crucible's volume. The ideal melting temperatures are 1064℃ for gold and 961℃ for silver. - For demolding, simply tilt the handle to pour out the molten metal. Once cooled, the ingot mold can be removed easily by tapping gently, eliminating the need for demolding agents. - Cleaning is simple: allow any residue to carbonize, then wipe the interior with a soft cloth to maintain its pristine condition. Invest in our crucible to elevate your metalworking, recycling, and laboratory processes, ensuring high performance and exceptional results every time.
