I did some simple sandcasting with a beginning jewelry class.
We carved a simple structure ( could make it abstract) out of styrofoam.
then burried it in a crucible( tin can) of sand with a hole in a cone
shape large enough to pour molten pewter into.
The hot metal automatically melts the styrofoam and replaces the shape
with hot metal. It cools almost instantly so students could achieve
instant success. Worked better with an abstract idea. We cleaned them up
with sandpaper and put in a tumbler to soften edges. Then epoxied eye
shapes of beads, nose shapes and mouth shapes. these became tiny masks
used as amulets. Then encorporated weaving and fibers to make an amulet
pouchto wear as a necklace or put in a pocket Got in lots of
multicultural art and art history along with the whole process. Kids
seemed to like the whole idea.
Hope this helps,
