Fire Assaying:
We determine the value of your lot by assaying the samples taken from it. The process used is fire assaying.
In classis fire assaying (actually a miniature refining process), the sample is first melted in a special furnace. The base metal is forced into slag, and the precious metals collected by lead at the bottom of the crucible. The lead is then oxidized and removed, leaving a bead of pure bullion, a precise sample of your entire lot. It is weighed as a basis of calculating the amount of precious metals in your shipment.
In all cases, duplicate samples are assayed independently and the results cross-checked for accuracy.
