Has anyone seen granulation with contrasting metals, for example gold
on silver? Or Argentium on gold? Or some other contrast?

...high caret gold onto sterling is quite easy because the silver melts at
a much lower temperature. No silver "solder"
such as "hard solder" is used. Still, I don't think you could call it a
fusion type of operation. I surmise what is actually going on is brazing.


There you go again! This is NOT brazing!

A couple of definitions of what brazing is:

1: A group of welding processes that produces coalescence of materials
by heating them to the brazing temperature in the presence of a filler
metal having a liquidus above (840°F) 450°C and below the solidus of the
base metal. The filler metal is distributed between the closely fitted
faying surfaces of the joint by capillary action.

2: A process that is used to bond similar or dissimilar materials by
melting a filler metal or alloy that is placed between the components
being joined. Brazes are filler metals or alloys that melt at
temperatures above 450 o C.

The emphasis is on FILLER metals!

I have asked you many times to stop dispensing "knowledge" of things you
know nothing or little of. Once again, please stop.
