Our Fire Assay Flux is a professional-grade reagent blend engineered for the precise extraction and analysis of precious metals from mineral samples. By combining high-purity litharge, dense soda ash, borax, and other essential reagents, this flux facilitates a seamless fusion process in the furnace, precipitating a Lead (Pb) button that serves as the foundation for accurate cupellation.
Designed for laboratory excellence, our flux powder undergoes rigorous quality control at every production stage to ensure consistency and reliability. Whether you require a standard composition or a customized recipe tailored to your specific sample matrix, we provide high-performance chemical solutions that deliver results precise down to parts per billion (ppb).

Frequently Asked Questions
Our flux is predominantly composed of Litharge, Dense Soda Ash, and Borax, with optional additions of Silica Flour, Baking Flour/Corn meal, and Silver Nitrate depending on the specific recipe.
Yes, Fiza specializes in producing flux according to customer-supplied recipes to ensure the reagent blend is perfectly adapted to your specific mineral sample matrix.
Powder litharge offers faster dissolution and blending, while granular forms may be preferred for specific handling or dosing requirements in larger industrial operations.
When used in a standard fire assay process, this method is capable of producing results so precise they can be specified in parts per billion (ppb).
Yes, we provide prompt international shipping with packaging tailored to meet safety regulations and your specific requirements.
The flux is combined with the mineral sample and heated in a furnace. This initiates a fusion process that precipitates the precious metals into a Lead (Pb) button, which is then cupelled to produce a prill.
