We used styrofoam to sculpt in college then buried it in sand outdoors and
left a small opening at top. Then we melted aluminum cans, siding, etc. in a
large crucible with a propane burner and poured that into the opening. The
styrofoam evaporates to a very, very toxic gas. Even outside you have to
stay away from the major noxious fumes. The evaporation metal castings were
great however, and not that expensive a project for adult sculpture artists.
