    hello Joanne, thanks for the advice.I am not casting myself, I am
    using a casting company which is very reputable, and has been
    experimenting a lot with different " de ox's". The last batch before
    they decided to give up on de ox totally were actually snapping as
    they came out of the investment, and those that didn't snap in two
    had cracks through them. I'll be passing on all the advice from 
    Orchid to them, Thanks, Christine
