This Purple Flux, formulated by Ronda Coryell, is a hard-soldering, self-pickling liquid flux specially created for the high-temperatures required when fusing Argentium® Silver. It helps hard solders flow smoothly at higher temperature ranges and will not pop or bubble during heating. Purple Flux also works great on most jewelry applications from low to high temperature soldering and brazing. Use with gold, silver, brass, bronze, nickel silver and other non-ferrous metals.
• Contains boric acid and ammonium choloride.
Effective temperature range: 1,100°–1,700°F (593°–927°C)
