Mabor Size 10 Cupels – High-Capacity Bone Ash Cupels for Assay

For metallurgists and gold hobbyists alike, these Size 10 Mabor cupels are indispensable for precise cupellation processes. 

Built to handle large assays or high lead oxide fluxes, making them ideal for gold and silver recovery in both industrial and small-scale operations.

Features:

    •    High Absorption Capacity:

The larger Size 10 format accommodates greater impurity absorption, making it especially effective for handling heavily fluxed assays or lead-based fire assays.

    •    Premium Bone Ash Construction:

Crafted with finely milled bone ash, these cupels excel in pulling lead oxides and non-metallic impurities away from the molten bead, ensuring a clean and pure metal recovery process.

    •    Heat Resilience:

Engineered to endure intense assay furnace temperatures, these cupels maintain structural stability and integrity even in high-stress environments.

    •    Consistent Results for Gold and Silver Refinement:

With unmatched porosity and absorbency, Mabor Size 10 cupels deliver reproducible results for refining and purifying precious metals to assay-grade standards.

Specifications:

    •    Material: High-purity bone ash

    •    Size: 10 (Large)

    •    Application: Designed for fire assays involving gold, silver, and other precious metals

    •    Recommended Use: Industrial-grade or hobbyist metallurgical operations

Why Choose Size 10 Mabor Cupels?

    1.    Precision for Gold and Silver Beads:

Their generous size ensures effective removal of slag and lead oxides from high-volume samples, ideal for nugget hunters, jewelers, and serious hobbyists refining gold concentrates.

    2.    Superior Impurity Absorption:

Size 10 cupels are preferred in situations where a high impurity load is expected, reducing the need for multiple rounds of cupellation.

    3.    Built for Larger Melts:

Larger cupels reduce spillage and enhance bead formation for those dealing with heavy concentrates or large flux additions.

    4.    Ideal for Complex Assays:

Perfect for situations involving alluvial concentrates, placer gold recovery, or heavily contaminated ore samples.

Best Practices for Use:

    •    Preheat Gradually: Warm the cupel prior to introducing the lead button to ensure even absorption.

    •    Monitor Bead Formation: Size 10 cupels provide excellent visibility of gold and silver bead formation during the cooling phase.

    •    Combine with Proper Fluxes: Optimal for use in assays that include a lead collector for efficient impurity separation.

Shipping Details:

    •    Packaged securely to prevent chipping or cracking.

    •    Fast dispatch and international shipping available.
