Product Construction

This crucible is manufactured from vitrified graphite, which forms the metal containment vessel used in furnace melting processes. The vitrified graphite construction is appropriate for furnace-based melting of precious and non-ferrous metals. This product is supplied without an external protective jacket. If you require a crucible supplied with a protective vitrified jacket as a complete assembly, see the Delmer Vitrified Graphite Crucible with Jacket.

Applications

This graphite crucible is used as a containment vessel for furnace melting of precious and non-ferrous metals. Relevant applications include:

• Gold melting — furnace-based melting of gold and gold alloys
• Silver melting — furnace-based melting of silver and silver alloys
• Precious-metal processing — melting and processing of precious metals where a graphite crucible is appropriate
• Jewellery manufacturing — melting precious metals for casting and fabrication
• Precious-metal refining — use in refining and recovery processes where a graphite crucible is appropriate
• Bullion and casting — melting metal for bar, grain or mould casting
• Induction and high-temperature furnace applications — for use in furnace types where a graphite crucible is appropriate

Suitability depends on the specific furnace type, chamber dimensions, operating conditions and metal being processed. Users should confirm compatibility with their furnace and process before use.

Technical Specifications

Crucible Without Jacket vs Crucible With Jacket

Selection between jacketed and unjacketed configurations should be based on furnace design, handling requirements and process conditions. Neither configuration is universally superior.

Gold & Silver Melting

Graphite crucibles are widely used as containment vessels for furnace melting of gold, silver and other precious metals. The Delmer Vitrified Graphite Crucible Without Jacket is suited to professional precious-metal melting operations where a graphite crucible without an external jacket is appropriate. Capacity and operating conditions must match the specific furnace and process requirements.

Jewellery & Precious-Metal Processing

This crucible is relevant to professional jewellery manufacturers, precious-metal processors, refiners and foundries that require a graphite melting crucible for furnace-based operations. It is used in applications including gold and silver melting for casting, grain production, refining and bullion manufacture. Suitability depends on the furnace type and operating conditions.

Delmer Furnace Compatibility

This crucible forms part of Delmer's graphite and ceramic furnace consumables range. Crucible selection should be matched to the furnace design, chamber dimensions, metal charge and operating requirements. Not all crucible configurations are compatible with every furnace. Contact Delmer for assistance in selecting the appropriate crucible for your furnace.
