Fusion for XRF analysis consists of mixing a ground sample with a borate flux (lithium or sodium) inside a 95% platinum / 5% gold crucible, heating around 1000°C with agitation until the flux melts, and then dissolving the sample homogeneously in the flux. The melt is then cast into a mold and cooled, resulting in a glass disk ready to be analyzed. The steps are the same for ICP analysis, except that the hot melt is poured into a beaker filled with diluted acid.
