We have two assay methods:
Fire Assay: This assay method is the oldest, most accurate, and remains the industry standard to determine gold and silver content. All lab work is done in-house by highly qualified and experienced employees to ensure accurate and prompt results. W.E. Mowrey will perform a fire assay for a $50 fee.
X-ray Fluorescence: This machine is able to scan the surface of an alloy and read its elemental makeup off its x-ray spectrum. We now offer X-ray analysis print outs for $25, the X-ray fluorescence machine is a great instrument, however it can be susceptible to error and it is not as accurate as a fire assay.
