[Favorite tips] Melting scrap

To all the scrap metal casters,

Here is another big secret for all. When melting scrap metal instead
of using a pinch of flux when the metal is molten, use a pinch of
table salt. It will help burn off the extra zinc used in the various
alloys. I have cast junk metal this way and it does work.
