How to Melt Silver Metals

Silver is a common precious metal that can be found in many homes. In some cases it may be desirable to melt the silver down. Scrap silver can be found in some old coins with no real numismatic value, old dental work, discarded jewelry, silverware and some consumer goods. It is also possible to have obtained raw silver ore or silver obtained from industrial applications. Silver can be melted down with reasonable preparation and care.

Things You'll Need

Crucible
Acetylene torch
Safety goggles
Gloves
Metal tongs
Borax
Mold

Instructions

- 1
  Place silver in a crucible that is safely secured. As the crucible is to become very hot, it is important that it will not become a hazard. Therefore, it should be located away from flammables and in a stationary clamp that will not allow it to be accidentally knocked over or dislodged. Also be certain it is clean of undesired debris.
- 2
  Add a pinch of borax for the flux. The flux creates an oxygen barrier to eliminate oxidation and separate the silver from other components. A flux is typically inert at room temperatures but act as a reducing agent at elevated temperatures.
- 3
  Heat the silver in the crucible with the acetylene torch. Pure silver melts at 1,763 degrees Fahrenheit, although alloys such as sterling silver and silver coins will often melt between 1,600 to 1,650 degrees Fahrenheit.

  Pour the molten silver into the desired mold once the silver has liquefied. Be sure to use the metal tongs to handle the hot crucible.
