Gas Forge brazing

In an article on brazing in a gas forge was advice to place item in a cold forge with brass brazing material in place and heat the forge until the brass melted then let forge cool and brazing is done. What about the flux in this method? How is it added? the only thing I can think of is to posibly dip the two items to be brazed in a water solution of flux while the items are hot and hope that they will get coated as the water evaporates and leaves flux on the metals. Anyone know of a simpler way? Is an even and complete flux coating even necessary or will it spread with the heating process?

GAS FORGE BRAZING

Maybe use a piece of brass rod that is already fluxed? I've brazed with a torch since 1973, but never in a forge. I'll have to try it, sounds interesting.... I look forward to hearing from someone that is experienced with this method.

I've done it in a coal forge w/ borax.

Forge Brazing

Go back and look at the old Anvils Ring where Elmer did brazing in the coal forge.

brazing

Yep me too. Borax for flux, copper wire for filler. I have been doing this on leaves to add color and brazing candle drip pans. The filler tends to go where the flux is.

"..........go where the flux is" . More so where the heat is.

Brazing

I CONCUR WITH DAN ON THAT ONE.

Yep, Dan and Ben is right.

Yep, Dan and Ben is right. Let me try again. The filler does follow the heat and will also flow into tight/clean/fluxed joints by capilliary action. I am not able to get filler to follow heat on dirty unfluxed metal. The leaves that I made were highlighted with copper by fluxing chased/chiseled grooves, placing snippets of copper wire and then heating in the forge. Wherever there was flux is where the copper would flow.

brazing

ALL surfaces that you want to braze should be bright and clean.
Flux or not.
