Smoke them the first 4 or 5 times you use them. It may be a good way of creating aluminum oxide on the face of the cavity. Other than that I have no idea why it works but it does. After a few sessions you will be able to cast without smoking.
Which is why I suspect it may have something to do with aluminum oxide.
