Fire Assay Flux is used in geochemical assay laboratories for detection of gold in ore samples. Our quality system guarantees the levels of gold in the fire assay flux are less than 1-1.5ppb in the litharge component of the flux, making it ideal for low level assay work.

The raw materials are certified for the use of fire test flow, the main ones are litharge or lead oxide with SGS certified amounts of gold <1 ppb and Silver<1 ppm. In addition is used Borax anhydrous, sodium carbonate, silicon oxide, fluorite, and other elements to order of each customer.
For each batch that is made for a given customer, a counter sample is left, which is kept for three months.
