Superior No. 6 brazing flux paste contains NO Potassium Bifluoride, making it a safer jewelry silver brazing flux choice for artisans and the metals being brazed.
Superior No. 6 jewelry brazing flux has been widely used by jewelry makers for more than 60 years. The absence of Potassium Bifluoride makes the flux safer on the skin than standard brazing flux paste in the event the flux makes contact with the skin. As with all fluxes, proper ventilation and Personal Protective Equipment should be used when brazing with Superior No. 6 flux.
