Cupel 12HB Tapered – High-Precision Cupel for Fire Assay
The Cupel 12HB Tapered from Mechelec is specifically engineered for high-accuracy gold and silver assay procedures. Ideal for hallmarking centers, refining labs, and metallurgical analysis, this tapered cupel is crafted with strict quality standards to deliver clean and reliable results during cupellation.
Made from premium bone ash or magnesia material, it features excellent porosity and thermal stability. This ensures it effectively absorbs lead oxide, allowing noble metals like gold and silver to remain isolated for accurate measurement. Its tapered design makes it easy to insert and remove from furnace holders, while also minimizing sample spillage or metal loss during transfer.
This cupel is suitable for use in high-temperature assay furnaces operating up to 1200°C. Its strong resistance to cracking and deformation under extreme heat ensures consistency in every batch. Whether you’re testing bullion, jewelry scrap, or ore samples, the Cupel 12HB Tapered supports a smooth and repeatable assay workflow.
In professional refining and hallmarking environments, precision matters. That’s why each cupel is subject to quality control checks that ensure dimensional accuracy, absorption efficiency, and low impurity content.
