    Yes it does. If you attempt to cast using rock salt, be very
    carefully, not only of yourself, but of the immediate surrounds.
    Dumping molten silver will release the elements chlorine and sodium
    from the chemical bonds, and suddenly you're standing in a cloud of
    chlorine. And I can't even imagine what the sodium is doing. I only
    know that when I was experimenting in ceramics we only did the salt
    glaze out in the country with forced air going when we threw the salt
    into the kiln. If you do attempt to use salt be very careful,
    especially of what's downwind. Use a respirator, a powerful fan, and
    use long tongs to pour with.
