Has anyone tried using a heavy gas such as argon to reduce the amount of dross created? It would certainly stay in the melting pot.

A small bit of beeswax, the size of a marble, added to and stirred into the melted babbitt just before pouring will put most of the tin back in suspension. The “dross” in most cases is the separation of tin or other alloys. Skimming and removing it can dramatically change the alloy percentage. I dont like the smoke created from beeswax, so just use dead dry pine shavings. You will be pleasantly surprised at how much of the dross goes back into the melt when fluxing it.
