The flux also serves the purpose of cleaning any contamination left on the brazing surfaces. Flux can be applied in any number of forms including flux paste, liquid, powder or pre-made brazing pastes that combine flux with filler metal powder. Flux can also be applied using brazing rods with a coating of flux, or a flux core.
Flux vapors tend to have low autoignition temperature and present a risk of a flash fire when the flux comes in contact with a hot surface. Solids – the percentage of solid material in the flux. Fluxes with low solids, sometimes as little as 1–2%, are called low solids flux, low-residue flux, or no clean flux. They are often composed of ...
Wets many surfaces incl. quartz, glass, and many ceramics. Deforms indefinitely under load. Does not become brittle even at low temperatures. Used as a solder in low-temperature physics, will bond to aluminium. Can be used for soldering to thin metal films or glass with an ultrasonic soldering iron.

Lead oxide is the traditional low temperature flux used for crystal glass, but it is now avoided because it is toxic even in small quantities. It is being replaced by other substances, especially boron and zinc oxides. [3] In clay bodies a flux creates a limited and controlled amount of glass, which works to cement crystalline phases together.
