   Is X-ray fluorescence a good test for gold?

   • X-Ray Fluorescence is less damaging to gold products than tests that require marring your gold with an unsightly scratch as some at-home methods work. XRF tests use x-rays that result in the metal emitting a fluorescent light on a cellular level. X-rays are non-invasive.

   How does a fire assay test for gold?

   • The process is designed to remove everything except gold. So if you weigh the sample you put in and the gold you get out, you can figure out how pure the sample was. However, the fire assay only tests for the amount of gold – it won’t tell you what else is in the sample. Another common test (this one is non-destructive) involves X-ray fluorescence.
