A small point of clarification:
"Soldering" is a process where by metals are joined via melting an
adhering-metal-alloy between the two pieces at temperatures LOWER than 800
degrees F. Joining techniques using a melted adhering-metal ABOVE that
temperature is call "Brazing". Using a silver alloy as the adhering metal is
properly referred to as "silver brazing" ("silver soldering" does not
commonly exist and is an incorrect reference to this method of joining
metals, albeit used by many persons, even some pro's who should know
better).
