Induction 3KG Crucible - Graphite with Ceramic Sleeve

Advanced Thermal Design This crucible features a high-purity graphite inner liner for maximum thermal conductivity and a clean pour. To protect the graphite from rapid oxidation at high temperatures, it is housed in a heavy-duty ceramic refractory sleeve, significantly extending the tool's lifespan compared to standard graphite crucibles. Key Features High-Volume Capacity: Optimized to hold up to 3kg of Gold (approximately 1.5kg–2kg of Silver). Dual-Layer Protection: The ceramic outer jacket provides superior insulation and structural integrity, preventing graphite erosion during induction cycles. Integrated Pouring Spout: Designed with a precision-notched lip for a smooth, controlled flow into molds. Induction Optimized: Specifically tailored for electromagnetic induction furnaces to ensure even heat distribution and prevent "hot spots." Works perfectly with the Pepetools 3KG Tabletop Induction Machine  Specifications Capacity: 3kg (Gold) / 155cc Max Operating Temp: 1300°C (2372°F) Material: Isostatic Graphite & High-Alumina Ceramic Compatibility: Fits most standard 3kg electric induction melting furnaces. Including the Pepetools 3KG Induction Melter  Dimensions Height - 114MM Diameter - 88MM Flange Diameter - 97MM   What’s in the Box? 3kg Graphite Crucible (Inner Liner) Vented Ceramic Lid Pro-Tips for Longevity Seasoning: Always preheat your crucible to 200°C for 15-20 minutes to eliminate any absorbed moisture before your first melt. Care: Avoid dropping cold metal ingots into a red-hot crucible to prevent mechanical shock.
