How important is the foil for sand casting?
I did this once and didn't use foil, just plastic boxes the size of shoe
I also understand that material backing is important to prevent cracking, is

The foil isn't that important...just helps lift the casting out of the box -
and keeps the box from getting soggy if you use cardboard. If you use
plastic, and it can bend some, then it's easy to get the casting out of
plastic too. You can skip the foil. I've never used a material backing, but
that's a good idea.
