Degassing molten Aluminium, advise needed : MetalCasting

Long version: The salt mix will act as a flux (not a degasser) that will lower the melting point of the aluminum slightly so it flows easier, which will help clean metal separate from the dross when you skim. You will notice your skim has less shiny aluminum in it and more grey powdery stuff, which is what dross is supposed to look like.

Fluxing Zinc in the Backyard Foundry – bolis.com

As I melted the flux chips into the zinc, stuff actually started to separate. The dross came up to the surface, and zinc formed into little balls and fell out of the dross pile back into the pool. Unlike aluminum, where the dross forms as a grey/black powder, the zinc dross came up as a soggy black blob of mush. But it seemed to be working.
