Silver in yellow brass solder

Is there any particular advantage to having silver in a yellow brass
solder, as opposed to just copper and zinc (or just adding zinc to
the brass you’re going to be soldering)? The yellow brass solders at
Rio both seem to have silver in them, as well as a formula I once got
from Hans Meevis. I’m most interested in getting a good color match
for ordinary (common) yellow brass.

Try the new brass paste solder from Rio. I used it on 70/30 brass
and the match was impressive. It can be mixed with silver solder to
lower its melting point, so maybe that’s the reason for the silver.
