Assay grade lead foil 99.99%, 0.1 mm thickness
99.99% purity assay grade lead foil (assay lead tape) gold free, and silver free for cupellation following the fire assay method.
Our assay lead foil or assay lead tape has also a low bismuth content, ensuring an exact analysis and is also in accordance with ISO11426 for the determination of gold in jewellery alloys (cupellation method fire assay).
The thicknes of our lead foil is 0.1mm. This allows to easily cut it with scissors, and to roll and compress it into a tight ball.
In order to give the best possible service and ensure an immediate supply, we stock lead foil with the following width:
Manufacturing is achieved by carefully laminating high purity lead ingots until the thickness of 0.1mm is obtained. Our lead foil has a high quality and is free of tears or other imperfections.
Furthermore, we provide a certificate of analysis for each purchase to ensure a full traceability of the product.
Finally, if not carefully packed, it can very easily be damaged and get torn during transformation. We therefore pack it very carefully to avoid this problem.
