Fluxes

Flux and the products that work with it for torch soldering. Paste and gel fluxes including Handy Flux and Jel-Flux, brush on and spray liquids such as Batterns, AquiFlux, Prip's and Firescoff, plus the traditional borax cone. Anti-flux and yellow ochre keep solder out of unwanted areas. Heat shield pastes and clays protect stones. Dispenser bottles apply flux precisely. Sizes run from quarter ounce bottles to one gallon. Some items ship as hazardous materials.
