2-1/2" Premium Bone Ash Cupel
2-1/2" Premium Bone Ash Cupel
Introducing the 2-1/2" Premium Bone Ash Cupel—a small, cup-like, porous container with a hemispherical depression design that concentrates heat at the center. Ideal for fire assaying and for collecting gold and silver from lead, this cupel supports precise metal separation and efficient recovery.
Crafted from bone ash, this cupel is designed for reliability in the lab or field. The hemispherical depression helps focus heat, improving consistency during fusion and cupellation. They typically absorb about 90% of the lead, with the remaining 10% turning into metal oxide so you can maximize yield and accuracy.
Key advantages include:
- Porous bone-ash composition for controlled reactions
- Hemispherical depression design for centered heat and even calcination
- Excellent lead absorption to optimize gold and silver recovery
- Compact 2-1/2" size suitable for standard assay setups
- Durable and reusable in proper conditions
Whether you're in a lab or working in field conditions, this cupel delivers reliable performance for fire assays and precious metal extraction. Invest in quality cupels for accurate results—add to your cart today and elevate your assay workflow.
