    Hi Juan,.......i just got back from a trip to a refiner a few weeks
    ago, where we melted about 200 pounds of an accumulation of
    photographic recovered silver. (among other melts) The smell you
    noticed was sulfur,......which burns off and at the refinery they
    have a venting system that sucks off the gas as it reaches the lip
    of the crucible. You're not likely to have such a system,.........so
    avoid brething the fumes as much as possible. 

    Our batch also had some black on the edges and one side,.....the
    other generally was silver in color. Nice thing about the stuff is
    that it generally is of a very high finess,........ours worked out
    to the high 98-99% range.
