will accept that sure changes occur when various heats are applied to.999Silver, but why would that be considered as damage? the tone of this seems to suggest that fusing temperatures are to be avoided in favor of lower temperature soldering techniques, which in practice will immediately render the precious metal in question no longer fine.
I think I was pretty clear on the reasons. If it is not enough, than
hit the books. It is very well documented subject.
