Detailed introduction
Assaying and Smelting
Smelting I think a lot of folks get confused between assaying and smelting. In fact, smelting is sort of the opposite of assaying. The black sand that was in our melt was oxidized to iron nitrate by the sodium nitrate and is now dissolved in the glass that we It Get price

What Is Borax and How Is It Used?
2020/1/31Borax is a natural mineral with a chemical formula Na 2 B 4 O 7 • 10H 2 O. Borax also is known as sodium borate, sodium tetraborate, or disodium tetraborate. It is one of the most important boron compounds.The International Union of Pure and Applied Chemistry Get price
How to Make Flux for Gold Refining
2017/4/12Refining gold from ore or concentrates is done during the smelting process. During this process, flux is used to dissolve contaminates such as metal oxides from the gold. The flux is added to a crucible with the gold that is then melted in a furnace. You can make Get price

Six reasons why boric acid is better than borax
Borax (also known as sodium borate, sodium tetraborate, or disodium tetraborate) contains two Sodium (Na) molecules and accounts for 12% of the molecular weight. Sodium increases the salinity of soil and water. This in turn affects nearby plants and wildlife. Get price

Salt vs Borax
In context|chemistry|lang=en terms the difference between salt and borax is that salt is (chemistry) one of the compounds formed from the reaction of an acid with a base, where a positive ion replaces a hydrogen of the acid while borax is (chemistry) the sodium salt of boric acid, na 2 b 4 o 7, either anhydrous or with 5 or 10 molecules of water of crystallisation; sodium tetraborate.

Question: Borax vs. Boric Acid : Metalfoundry
2013/11/27I'm under the impression that either borax or a mixture of borax and boric acid will do a better job as a flux for casting brass than boric-acid alone. I'm also under the impression that boric acid, once brought up to pouring temperature is slightly more destructive to refractory and crucible materials, although both of them do damage. Get price

How to Understand how sodium nitrate burns Science
Ever wondered how science could turn out to be fun? Here's how: take a piece of paper with a mixture of sodium nitrate and sugar. When heated, sodium nitrate releases oxygen and burns sugar. Sugar alone cannot burn fast. If you want faster results, then take sodium nitrate with sulphur and some reactive metals. Add some coal to it for a faster result. This will help you burn some useless pile Get price
