Temperature
Appearance of flux
212°F (100°C)
Water boils off.
600°F (315°C)
Flux becomes white and slightly puffy, and starts to "work."
800°F (425°C)
Flux lies against surface and has a milky appearance.
1100°F (593°C)
Flux is completely clear and active, looks like water. Bright metal surface is visible underneath. At this point, test the temperature by touching brazing filler metal to base metal. If brazing filler metal melts, assembly is at proper temperature for brazing.
