Smelting uses chemicals (flux), to oxidize or reduce metals, the chemicals (ingredients of the flux) have to be chosen for the chemical reaction you need to achieve, a collector metal may be needed to collect the gold from the melt, or you may be able to use flux to oxidize the metal into the slag away from the gold, the flux also has to ...

Flux helps to clean impurities and oxidation from the surfaces of those metals so that the solder can bond with the pure metal, creating a strong connection. It also helps solder to flow more easily. Otherwise, it would form beads, or lumps. Metal workers, jewelers, and crafters use flux frequently and it is possible to make your own flux at ...

Hi, I'm getting married next week (hence my panic), and we planned to sand cast our own wedding rings. I conveniently work for a furnace company, who let me use a furnace to melt the gold, and the first ring turned out perfectly. 10g of10ct gold in a 1100*C furnace with a dash of borax powder.

Liquid flux is produced using a 20-65% concentration of rosin; at concentrations of 65-80% of rosin, a paste flux is produced; I'm going to have to try this. I like the idea of being able to control the consistency of the flux, which beats buying 5 different commercial products to have the same variety.

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. You can increase the amount of flux by a pinch or two if the gold is particularly dirty. However, be careful not to apply excessive flux; flux containing borax 'eats' through ceramic crucibles ...

Ingredients for Homemade Flux. Most homemade flux recipes use simple, easy-to-find ingredients. The key components of flux are: Borax – Acts as a cleaning agent and prevents oxidation. Boric acid – Enhances metal wetting and oxidation resistance. Salt – Helps flux stick to the metal surface. Water or alcohol – Used to mix and dissolve ...

Prips flux is not as active as the white paste fluxes, so a good fit, and clean metal are even more important, but that's standard good soldering practice anyway. And while this may seem more fuss, the raw materials of the flux are really cheap. I mix up Prips flux by the quart about every year or two, and the boxes of chemical I

litharge is only necessary when doing a fire assay or fine gold. GPK Premium Black Flux is recommended for melting pure gold, or smelting gold ore concentrates. The black flux is designed to help remove impurities from gold, including copper, silver, etc. It will treat them as a base metal and oxidize them.

If you are a true masochist, filing down to bright steel will allow you to use clean sand as flux as long as you apply it below scale-forming temperatures. Heavy, deeply pitted rust can cause problems with any weld, no matter how modern the forge and flux. If you are welding cable, internal rust can ruin the whole thing and no flux will remove it.
