Soldering is a process by which two metal objects are joined together. This technique works by melting a composite metal and dripping it onto a material called “flux,” thereby joining two metal pieces into one. Silver is widely used for brazing or hard soldering. This type of soldering is ideal for structural joining, used to fill gaps, and acting as glue in items, like jewelry.
Silver solder is typically in the form of silver wire wound around a spool. This form of silver makes it easy to position the end of the wire in an area to be joined. The wire is then melted with a heating device, such as a torch. The silver solder drips into the seam between the two pieces to be joined, after they have been coated with a flux material. Borax is often used as a flux. High silver content in solder insures a strong joint, for structural purposes.
