What is self pickling flux?
Batterns Self-Pickling Flux is used for hard soldering (solder that melts at a high temperature) of gold, silver, and platinum. It can be diluted with distilled water if it’s too thick. Don’t be fooled by the name. You’ll still need to pickle the item before soldering.

What flux is used for silver?
Stay-Silv® White Brazing Flux This is a white paste flux that’s used for 90% of silver brazing applications. White flux is useful for brazing copper, brass, steel, stainless steel, and nickel alloys.
What flux is used for gold?
Maganese Dioxide is used as an assaying flux ingredient for melting or smelting gold and other precious metals.
Why is borax used as flux?
A mixture of borax and ammonium chloride is used as a flux when welding iron and steel. It lowers the melting point of the unwanted iron oxide (scale), allowing it to run off. Borax is also mixed with water as a flux when soldering jewelry metals such as gold or silver.
What can be used as flux?
Rosin is the same organic material as flux so it is already built into the solder. If you have this type, you do not need to use more flux. The solder will clean the surface as it melts. Acid core solder will also clear metal surfaces of oxides as well as corrosive by-products.
Can I use any flux for silver?
The general fluoride/borate-type flux, such as Handy Flux (FB3-A), will dissolve the oxides, but the consistency of the flux should be used in standard form, not diluted. With some larger parts, Handy Flux Type B-1 (FB3-C) may be more appropriate because of its extended heat range/life.
What can I use as flux when melting gold?
Heating bicarbonate or baking soda (not to be confused with baking powder) will produce sodium carbonate. Mix borax and sodium carbonate in equal portions to form an effective DIY flux. For each ounce of gold you want to melt, add 3 to 4 pinches of flux.
Can you use borax as flux?
One particular practice that many wonders about is the use of borax in the process of forge welding and blacksmithing. Blacksmiths use borax as a flux, which is an agent that cleans and purifies the metal being joined in the forge welding process.
Is borax a good flux?
Flux. A mixture of borax and ammonium chloride is used as a flux when welding iron and steel. Borax is also a good flux for “pre-tinning” tungsten with zinc — making the tungsten soft-solderable. Borax is often used as a flux for forge welding.
Can you use any borax for flux?
I use plain old laundry borax – works just fine.
