Solder - tests and outcomes

The traditional construction and fabrication techniques used by jewellers to create volumetric three-dimensional forms invariably require the use of silver solders. It is the received wisdom that to enamel directly over a solder seam is problematic and should be avoided. In order to test this a number of seams were produced using different types of silver solder and a variety of enamels were sifted directly across the seam and fired. The results are outlined below.

All test were made using 1mm copper sheet. Solder was applied from the back and excess solder was removed from the front surface with a file prior to the application of enamel.
Each piece was fired twice at approx 800 degrees centigrade.
