Re: FW: [ATM] re Aluminium casting

["Richard Schwartz" <richas@earthlink.net>]

Melting aluminum cans does not work.  I have tried it, and it leads to
aluminum cans turned to a crusty oxide.

Has anybody successfully melted aluminum cans and aluminum foil ?   I don't
want to buy a vacuum furnace.

Does anybody know a good source for cryolite?   Perhaps that could flux the
aluminum and shield it from oxygen before it oxidizes.
