Tooltos Ceramic Crucible for Metal Melting | Electric Furnace 1KG 2KG 3KG

Built for Cleaner, More Reliable Non-Ferrous Metal Melting

Graphite crucibles oxidize quickly and introduce carbon into your melt — affecting purity and increasing replacement costs. The Tooltos High Temperature Ceramic Crucible offers a cleaner alternative: oxidation-resistant, dense ceramic construction purpose-built for copper, aluminum, brass, and bronze melting in electric furnaces. Available in 1KG, 2KG, and 3KG capacities to match your batch size and furnace model.

Key Features

• 1000–1100°C Maximum Temperature — Handles copper, aluminum, brass, and bronze melting temperatures without degradation.
• Oxidation-Resistant Ceramic Body — Produces cleaner melts with no carbon transfer, ideal for non-ferrous metal work where purity matters.
• Double-Ring Opening Design — Provides a stable grip point for crucible tongs during pouring, improving safety and control.
• High-Density Construction — Consistent performance across repeated heating cycles, reducing replacement frequency.
• Three Sizes Available — 1KG, 2KG, and 3KG to suit small workshops through small-scale metal processing operations.
• Furnace-Ready Replacement — Drop-in replacement for standard electric melting furnaces, including Tooltos models.

Best For

• Metal workshops melting copper, aluminum, brass, or bronze
• Users replacing worn or damaged crucibles in electric melting furnaces
• Casting studios and repair shops needing reliable daily-use crucibles
• Users who want cleaner melts with less carbon contamination than graphite
• Small-scale non-ferrous metal processing and casting

Not For

• Precious metal melting — this crucible is not suitable for gold, silver, platinum, or other precious metals
• Torch or open-flame melting applications — graphite crucibles are better suited for direct flame
• Iron or steel melting — exceeds the recommended temperature and material range
• Users who have not confirmed furnace chamber size compatibility before ordering

Size Selection Guide

First Use and Operating Guidelines

1. Inspect — Check the crucible for cracks or chips before first use.
2. Dry — Ensure the crucible is completely dry before heating.
3. Preheat — Gradually increase temperature to avoid thermal shock.
4. Load — Add metal charge without exceeding rated capacity.
5. Melt — Operate within the 1000–1100°C range for best results.
6. Cool — Allow natural cooling only. Never quench with water.

Pro 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 only. For torch applications, graphite crucibles are better suited to handle direct flame.

What metals can I melt in this crucible?
Copper, aluminum, brass, bronze, and similar non-ferrous metals. This crucible is not suitable for precious metals such as gold or silver.

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. Please 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 non-ferrous metal work where purity matters.

How do I choose the right size?
Choose 1KG for small copper or brass melting, 2KG for aluminum casting or larger copper work, and 3KG for batch processing or small-scale non-ferrous metal operations. When in doubt, refer to your furnace chamber specifications.

What's Included

• 1 × Tooltos High Temperature Ceramic Crucible (selected size)

Safety Notes

• For electric melting furnace use only — not suitable for open flame or torch applications.
• Not suitable for precious metals such as gold or silver.
• 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.
