to be near invisible anyway.
The silver solder that plumbers use for copper pipe is usually only 2%
silver
Can't for the life of me think of any application where a plumber rather

say a boiler manufacturer would need to use silver solder and especially
one
with such low silver content
Commonly used in refrigeration and other compressed gases.
Also for large diameter copper pipes.
