    I took everyones advice and cast with a shorter and larger sprue with
    a resivior and I switched to silver as I don't know for sure the
    melting point of this bronze. It cast really well so I think I have
    the issue fixed. I am doing a 10 kt gold cast tonight I hope to have
    good results. 

    I got a pyrometer also and found that pretty much every machine I had
    was un calibrated to some degree one was off by 100 degrees which
    prolly doesn't make things better. It's a digital pyrometer for 70
    dollars I'll not spam the link cause I dunno the rules about that if
    you e-mail me i'll send it to you. Thanks for all the help.
