About this product
We supply a wide range of high-purity ceramic crucibles — from precision laboratory labware through to large-scale industrial crucibles — all engineered for high performance in extreme temperature environments. The range covers lab-scale alumina, quartz and zirconia crucibles for testing and small-batch melting, through to dense engineered crucibles and large refractory bodies for multi-tonne molten metal volumes. Available alongside complementary boats, dishes, furnace tubes and casting system components for full system integration.
What that means for you
High temperature resistance
Engineered to perform reliably up to 2500°C, suitable for precious metals, rare earth processing and demanding melt operations.
Thermal shock performance
Optimised to withstand rapid heat changes without cracking, distortion or premature failure.
Chemical corrosion resistance
Excellent stability against aggressive molten metals, alkaline vapours and corrosive furnace atmospheres.
Custom sizes & complex shapes
Standard or tailored designs — from lab-scale to multi-tonne — enabling precise matching to your furnace and melt volumes.
High-purity dense ceramic options
Material purity and structure directly improve crucible life, reduce contamination risk and deliver cleaner end-product melts.
Labware & furnace integration
Large in-stock range of crucibles, boats, dishes and tubes supports quick replacements, faster changeovers and minimal downtime.
Reliable melting performance at extreme temperatures, consistent product quality across repeated thermal cycles, longer life in production, and the confidence your crucibles will meet demanding technical requirements without excessive maintenance, disruption or cost.

Your questions answered
What's the maximum temperature your crucibles can handle?
Up to 2500°C depending on the material — zirconia grades operate at the highest end, while alumina handles up to around 1750°C for clean melting service.
Do you offer crucibles for precious metals or rare earth processing?
Yes. We supply high-purity alumina, zirconia and yttria-based crucibles specifically engineered for clean melting of precious metals, rare earth elements and high-value alloys.
Can you supply crucibles for multi-tonne molten metal volumes?
Yes. Our refractory crucible range includes sectional units capable of holding large molten metal volumes, manufactured to your specific furnace configuration.
What sizes do you have in stock?
We hold an extensive in-stock range of crucibles, boats, dishes and complementary labware in standard sizes — supporting quick replacements and faster changeovers.
Can I order a bespoke crucible shape?
Yes. Both standard and custom geometries can be supplied, from small lab-scale crucibles to large-format industrial units. Send us your drawing or specification.
