    I had a problem of a similar nature and it turned out that the
    crucible I was using was designed for casting gold, which is denser
    than silver and the molten metal couldnt pass through the spout fast
    enough and was acting as a slug and then going over the open top. I
    bored out the crucible hole a bit and it was fine. Note: this worked
    for this particular set up so would speak to your supplier to make
    sure that you dont have a similar problem before attacking your
    crucibles with a drill as you may end up throwing silver through the
    bottom of your investment flask instead!
