What flux is used to smelt silver?

Step 1: Collect the necessary materials

To smelt silver, you will need silver ore, a source of heat such as a furnace or torch, a crucible, and a flux.

Step 2: Prepare the crucible

Place the silver ore in the crucible, making sure it is clean and free of any impurities.

Step 3: Add the flux

The flux commonly used to smelt silver is borax. Borax helps to lower the melting point of the silver ore and removes impurities from the molten metal.

Step 4: Heat the crucible

Apply heat to the crucible using a furnace or torch. The high temperature will cause the silver ore and flux to melt together.

Step 5: Remove impurities

As the silver ore and flux melt, the impurities will separate and rise to the surface of the crucible. Skim off the impurities using a tool like a spoon or ladle.

Step 6: Pour the molten silver

Once the impurities have been removed, carefully pour the molten silver into a mold to solidify.

Step 7: Let the silver cool

Allow the silver to cool and harden in the mold before removing it. The result will be a pure silver ingot ready for further processing or use.By following these steps and using borax as a flux, you can successfully smelt silver and obtain pure metal for various applications.
