Fire Assay Analysis

Fire Assay AnalysisThe fire-assay procedure is an age-old practice and is most widely accepted as the standard in the jewelry industry when determining the gold and silver content. Making United superior with our speed and accuracy is our state-of-the-art analytical department. We perform three separate fire assays with each individual lot. To insure the maximum returns, we utilize our two-step process of fire assay and X-ray Fluorescence.  I.C.P. technology is also used to determine the platinum group metals contained in the melt. All our gold and silver bearing alloys, grains, solders, wire and sheet are fire assayed to assure their precious metal content. A certificate of analysis is also provided for each and every batch of product manufactured at United.
