Graphite crucibles oxidize quickly and introduce carbon into your melt. The Tooltos High Temperature Ceramic Crucible offers a cleaner alternative — oxidation-resistant, dense ceramic construction purpose-built for gold, silver, and copper melting in electric furnaces. Available in 1KG, 2KG, and 3KG capacities to match your batch size.
Key Features
1000–1100°C Maximum Temperature — Handles gold, silver, and copper melting temperatures without degradation.
Oxidation-Resistant Ceramic Body — Produces cleaner melts with no carbon transfer, ideal for precious metal work.
Double-Ring Opening Design — Provides a stable grip point for crucible tongs during pouring.
High-Density Construction — Consistent performance across repeated heating cycles.
Three Sizes Available — 1KG, 2KG, and 3KG to suit small workshops through small-scale refining operations.
Furnace-Ready — Drop-in replacement for standard electric melting furnaces.

First Use and Operating Guidelines
Inspect — Check the crucible for cracks or chips before first use.
Dry — Ensure the crucible is completely dry before heating.
Preheat — Gradually increase temperature to avoid thermal shock.
Load — Add metal charge without exceeding rated capacity.
Melt — Operate within the 1000–1100°C range for best results.
Cool — Allow natural cooling only. Never quench with water.
Professional Tips
Preheat slowly on first use to cure the ceramic body and extend service life.
Use proper crucible tongs — the double-ring design provides a secure grip point for safe pouring.
Store in a dry location to prevent moisture absorption before use.
Inspect after each use — hairline cracks indicate the crucible should be replaced.
Dedicate one crucible per metal type to avoid cross-contamination between alloys.
Frequently Asked Questions
Can I use this crucible for torch melting? This crucible is designed for electric melting furnaces. For torch applications, graphite crucibles are better suited to handle direct flame.
What metals can I melt in this crucible? Gold, silver, copper, brass, bronze, and most non-ferrous metals. Not recommended for iron or steel.
How many uses can I expect per crucible? With proper care — gradual heating, no thermal shock, dry storage — ceramic crucibles typically last 20–50 melting cycles depending on temperature and metal type.
Is this compatible with Tooltos melting furnaces? Yes. These crucibles are designed to fit standard Tooltos melting furnaces. Verify the size matches your furnace chamber before ordering.
Why ceramic instead of graphite? Ceramic crucibles are more oxidation-resistant and produce cleaner melts with less carbon transfer — ideal for precious metal work where purity matters.

Safety Notes
For electric melting furnace use only — not suitable for open flame or torch applications.
Always preheat gradually before reaching full operating temperature.
Keep dry before heating — moisture causes cracking.
Never quench with water after use — allow natural cooling only.
Handle with care — ceramic is brittle and will crack from impact.
