Capacity should be selected according to the required metal charge, furnace design and process requirements. Contact Delmer if assistance is required in selecting the appropriate capacity.
Product Construction
This product consists of a graphite melting crucible supplied together with a protective vitrified jacket. The graphite crucible forms the metal containment vessel in which the metal charge is placed and melted. The jacket surrounds the crucible and provides additional mechanical protection and support during handling and furnace use. Both components are supplied together as a complete assembly.
Why Use a Jacketed Crucible?
A jacketed crucible differs from a standard unjacketed crucible in that it includes an external protective jacket fitted around the graphite crucible body. The jacket provides additional mechanical protection and support, which can be beneficial during handling and furnace loading. Users should assess whether a jacketed or unjacketed configuration is appropriate for their specific furnace design and operating procedures.
Gold & Silver Melting
Graphite crucibles are widely used as containment vessels for furnace melting of precious and non-ferrous metals, including gold and silver. The Delmer Vitrified Graphite Crucible with Jacket is available in capacities from 2 kg to 20 kg to accommodate different batch sizes. Capacity selection and operating conditions must be appropriate for the specific furnace and process. Users should confirm that the crucible capacity and configuration are compatible with their furnace before use.
Jewellery & Precious-Metal Processing
The Delmer Vitrified Graphite Crucible with Jacket is relevant to professional jewellery manufacturing operations that require reliable furnace-based melting of gold, silver and other precious metals. It is also applicable to precious-metal refining, casting and related processing applications where a graphite melting crucible with protective jacket is required. As with all furnace consumables, suitability depends on the specific furnace, process conditions and operating requirements.

If you are unsure which capacity is appropriate for your furnace and process, contact Delmer for assistance.
Jacketed vs Non-Jacketed Crucible
| Configuration | Description |
|---|---|
| Jacketed | Graphite crucible supplied with a protective vitrified jacket; provides additional mechanical protection and support during handling and furnace use. |
| Non-Jacketed | Graphite crucible supplied without an external jacket. See the Delmer Vitrified Crucible without Jacket. |
Neither configuration is universally superior. Selection should be based on furnace design, handling requirements and process conditions.
