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

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.
