I just picked up some silver solder paste.....

and I noticed something very peculiar about this stuff.  It looks and
smells EXACTLY like 'high end' silver thermal paste for CPU's !!  Has
anyone else noticed this ?

I haven't yet used the stuff to 'actually solder' yet but I'm looking
forward to trying it out.  Does anyone have a preference to the types
of solder they use for joining COPPER and SILVER (both fine and
sterling)  ?

I also grabbed some Hard, medium and soft 'sheet solder' but it would
seem to me that it would be much more difficult to use than the silver
'PASTE'.  Of course, I'm speaking strickly as a beginner when it comes
to joining these various metals....  Am I wrong in this assumption ?
