However cuppeling will remove the lead or bismuth carrier, as well as base metals such as copper present through oxidation, leaving the precious metal button behind. The button left behind should be .99 fine. **Q: How many oz of silver can it hold at once** A: These cupels are for fire assaying. Probably 1-2 grams max. If you use them to melt only, may get 1toz in it(not very deep). **Q: Can you use this in a propane furnace like a devil forge?** A: Iā€™m not sure. These cupels are for assaying. If you are melting I would suggest clay graphite or silicon carbide crucible. ## Frequently Bought Together - Lot of 8 - # 8AM Mabor Cupel 1-3/4" Gold-Assay-Smelting-Refining-Melting-Cupels - Borax Flux 1/2 Pound Melting Gold Silver Crucible Glaze Jewelry Casting 8oz - Lot of 6 - # 10 Mabor Cupel 2-3/8" Gold-Assay-Smelting-Refining-Melting-Cupels --- ## Why Shop on Desertcart? - šŸ›’ **Trusted by 1.3+ Million Shoppers** ā€” Serving international shoppers since 2016 - šŸŒ **Shop Globally** ā€” Access 737+ million products across 21 categories - šŸ’° **No Hidden Fees** ā€” All customs, duties, and taxes included in the price - šŸ”„ **15-Day Free Returns** ā€” Hassle-free returns (30 days for PRO members) - šŸ”’ **Secure Payments** ā€” Trusted payment options with buyer protection - ā­ **TrustPilot Rated 4.5/5** ā€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/380108820-lot-of-8-8am-mabor-cupel-1-3-4-gold](https://www.desertcart.tn/products/380108820-lot-of-8-8am-mabor-cupel-1-3-4-gold) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-26*
