    The above quote from Jim Binnion was in a posting under this thread
    of "My apprenticeship." One of my frustrations with this forum is
    that my reply and any other relevant postings on this tangent will
    still be under "My apprenticeship", rather than being part of a new
    thread called "Annealing". At least, that's the way it seems to work.
    Does it have to? 

    Now to Jim's quote. I often have to bend heavy bracelets that have
    some sections that are thicker/wider than others. So, as I'm pounding
    one around a mandrel with a heavy nylon-faced mallet, I have to be
    careful with the "weaker" sections. I might anneal a piece 2 or 3
    times before I'm done. 

    Now, in light of what Jim says, I'm wondering if the pounding I'm
    doing actually does work-harden the piece enough to justify
    additional annealings. Maybe I'm being overly cautious, but breaking
    an important piece while bending it is a frustration I don't want to
    repeat. But I sure don't want to compound the problem by
    over-annealing. 

    So, how does hitting silver with a nylon mallet compare to
    striking/reducing/raising with a metal hammer, when it comes the
    need to anneal? Thanks!
