If plumbers did actually use silver solder (of whatever percentage
silver content), you'd expect them to be able to buy the stuff in
plumbers' merchants, would you not?

Funny how BES and Screwfix don't appear to sell it. (Of course, maybe I
am simply crap at finding it.)


What is the case is that all or nearly all 'lead free' solder has a very
small trace of silver in it, so certain people who are ego driven and
want to win arguyments rather than impart information, have claimed that
this is 'silver solder' when that term was claimed years ago by high
temperature solders used in brazing with significantly high silver
concentrations.

Remember the old legal ruling years ago that 'salmon paste' had to have
at least 15% salmon in it, whereas 'Fish paste - Salmon' - need have
less than 5%?

Or something.
