    Hi All, Somewhat related to my previous post about rolling mills, I
    am going to purchase one primarily to be able to create some stock a
    little heavier than the 10ga I can easily get. In the past my
    attempts to recycle scrap sterling met with disaster-crumbly pitted
    ingots the norm. I was using "clean scrap" ie no solder but it had
    been heated. I don't recall how I cleaned it but I was using a high
    quality flux in the melting of it. I mastered getting a nice pour
    with no folds but even annealling after every pass through the mill
    gave me the same resluts. 

    This time I'm determined to get it right even if I have to use
    casting grain. I'm not interested in recycling as much as the
    finished product. Would fresh casting grain be a solution? Any secret
    fluxes or crucibles? ingot molds? I was using the 2 piece molds
    getting 3"x5/8" ingots but tried th longer oepn molds with worse
    results. 

    Any ideas would be great. Thanks, Warren Allen
