Tooltos White Clay Crucible Bowl | 62x27mm, Gold Silver Copper Smelting
- 98 in stock
Description
Key Selling Points
- White clay construction provides a clean, non-reactive vessel for smelting gold, silver, copper, aluminum, and brass — the white clay body does not introduce contamination to precious metal melts
- Bowl shape (62mm diameter x 27mm deep) provides a round, open vessel suited for melting small quantities of metal and pouring directly from the crucible
- Compatible with fuel furnaces, kilns, natural gas furnaces, coke ovens, and coal furnaces — works across the common furnace types used in jewelry and metalworking studios
- Lightweight at approximately 29g — easy to handle with crucible tongs during and after heating
About This Crucible Bowl
The white clay crucible bowl is a traditional refractory vessel used for small-batch metal melting in jewelry and metalworking studios. The 62mm diameter and 27mm depth provide enough capacity for melting small quantities of precious metal scrap for re-casting or refining, while remaining compact enough to heat quickly in a bench-top furnace. The round bowl shape allows the molten metal to pool centrally, making it straightforward to pour into a mold or ingot form.
White clay crucibles are a practical choice for general jewelry studio use — the material handles repeated thermal cycling well and the white body makes it easy to visually inspect the crucible for cracks or contamination before each use. The 62mm bowl is well suited for jewelers melting scrap gold or silver, preparing small alloy batches, or casting directly into simple molds.
Crucible Material Comparison
| Feature | White Clay — This Model | Alumina Clay |
|---|---|---|
| Size | 62 x 27mm | 65 x 28mm |
| Visual inspection | White body — cracks and contamination easy to see | Darker body — standard inspection required |
| Best for | General jewelry studio melting, precious metal scrap | General jewelry studio melting, slightly larger capacity |
Best For / Not For
| Best For | Not For |
|---|---|
| Small-batch melting of gold, silver, copper, aluminum, and brass for casting and refining | Large-volume production melting — the 62mm bowl is suited for small studio quantities |
| Melting scrap precious metal for re-casting into ingots or pouring directly into molds | Sudden temperature changes — always preheat gradually and avoid cold contact when hot |
| Use with gas, fuel, coke, coal, and kiln furnace types | Highly corrosive fluxes that can erode the clay body — check flux compatibility before use |

Pro Tips
- Preheat the crucible at a low furnace setting for several minutes before bringing it to full temperature — gradual heating prevents thermal shock cracking.
- Season a new crucible before first use by heating it empty to working temperature and allowing it to cool slowly — this stabilizes the clay body and extends service life.
- The white body makes it easy to spot cracks, discoloration, or metal residue from previous melts — inspect carefully before each use and replace if any cracks are visible.
- Place the hot crucible on a heat-resistant ceramic or refractory brick surface after removal from the furnace — never on a cold metal surface, concrete, or near water.
- Dedicate separate crucibles to different metals where possible — residue from one metal can contaminate the next melt if the same crucible is reused across different metal types.
Frequently Asked Questions
What is the difference between white clay and alumina clay crucibles?
Both are refractory clay materials suited for jewelry studio metal melting. The white clay body makes it easier to visually inspect for cracks and contamination before each use. The alumina clay version (65 x 28mm) is slightly larger. Both are compatible with the same metals and furnace types at similar price points — choose based on size preference or availability.
How many times can this crucible be reused?
Service life depends on the metals used, furnace temperatures, and how carefully the crucible is handled. With proper preheating, gradual cooling, and careful handling, clay crucibles can be reused multiple times. Inspect before each use and replace if cracks appear.
