Using Powder Solder
Powder Solder is not a familiar tool to most metal smiths and jewelers. We are used to using pallions and wire to which we add flux. Powder Solder differs in many ways. It can be placed in an exact position and very little solder needs to be put at point of connection. The most common application of powder solders is for filigree work and in plique a jour enameling. In order to have the powder solder flow, a flux must be utilized. Paste flux is applied to the area to be joined and then powder solder is sifted over the flux. Heat is then applied to the pieces to be joined by the solder. One consideration when using powder solder is that you must go in very quickly with a hot torch flame. If you are too timid with applying the heat, you will find a crustiness develop from the solder. This tells you that you have reduced the oxygen, and will therefore not be able to complete a successful soldering operation.
