flux | ˈfləks
noun
A material used in soldering
Flux is a type of material used in the soldering process for jewelry. It is a compound that helps keep the joints clean during soldering. This in turn blocks oxygen from impacting the metals, reducing the risk of oxidation. Flux is used to clean, coat and protect the piece during the soldering process, ensuring the solder reaches all elements of the joint when heated and without causing any negative side effects. There are multiple types of flux that might be used, including coating flux to protect against oxidation and fire scale and flow flux to help melt the solder without additional oxidation.
