Assay quality sterling silver solder paste supplied in a syringe with two precision needles. The solder is pre-mixed with flux so there is no need to use additional flux. Cadmium free. Available in four different grades: extra easy, easy, medium and hard, each with a different melting point. The different flow temperatures make it possible to solder a piece multiple times without melting previous joints. Start with hard solder and finish with extra easy.  

Highly versatile for quick accurate soldering jobs where precision is needed and a little goes a long way.
