>     Maybe I'll try Cupronil next. 

    I've used Cupronil (spraying or painting it on) for a couple of
    years and find that it does a good job, 

    Although, I too struggle with sodering large bezels and doing
    several soldering steps on each piece. Sometimes I do have fire scale
    on the back of the piece - probably because I've gotten the thing too
    hot trying to fill in gaps between the bezel and the back plate. 

    Soldering large bezels is another subject I know - I love Argentium
    because of the no fire scale among other things but have given up on
    it for large stones. The solder just will not flow all the way around
    - I end up with horrendous piles of solder, melted bezels from
    heating from the top (heating from the bottom results in too much
    sag). I've tried all the different solders recommended and most
    recently tried jel-flux. I have an order in for the new argentium
    paste solder but it is on back order. I also anneal the back plate.
    If any one has any other suggestions I would be most grateful. 

Thanks,
Jan
