So would it be safer to wait till the pot is just about empty and then add more ingots, as if almost starting from the beginning instead of adding to say, a half filled pot? Is the theory then that the ingot melting slowly from the bottom up, will be less likely to explode than if was dunked into a half pot of already molten lead? I would have thought that no matter what, if there is water/ moisture no matter how introduced, would still be the same effect no? Either way it has me a little paranoid that it may happen again. It's a heck of a mess to clean up!
