[Elecraft] Organic Rosin Core Solder

[David F. Reed]

Folks;

It would seem to me to not be from rosin or resin core solder; if it is 
corrosion, it sounds more like acid core solder; perhaps it was mislabeled.

The term organic unfortunately is frequently misused; all hydrocarbons 
are organic right?  Water soluble?  I assume the flux, as in wash after 
soldering?

Flux is typically to form a layer that on the surface that inhibits the 
immediate corrosion (due to the higher temperature of the melted solder) 
and help it wick to the untinned surface you are trying to solder to I 
think.
