Superior No. 6 jewelry brazing flux is RoHS compliant.

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.
