Steve,

Well, I guess with 2200 lb. of solder in the pot, it should take a long time to get
your contamination level up.  I have mixed brands a couple of times over my many years
at this.  I have never seen a problem.  This action was usually done when we changed
vendors and we would just start introducing the new vendors bars during the normal pot
replenishment.

Cheap solder - no such thing, your paying somewhere.  Have contamination levels check
on a sample of what ever you consider.  I also like to melt a sample myself, just to
see how much dross pops out of it. I don't need to buy dross - I can generate all I
want by myself.
