Hi

    I have had the same problems, sometimes the only way I've been able
    to stop the cracking is to add virgin(?) gold, but I've also found
    that it is very important to add sufficient boric acid to the
    crucible when you melt the gold. I assume it keeps the oxidation in
    check. I'm not a schooled jeweler, just 40 years of trial and error.
    This may have no basis but it has worked for me.
