- Sand has always been used for iron casting. Remember, sand comes in different
'grits' and you can 'face coat' with a finer sand, then follow with bigger
stuff for strength. I poured 4 or 5 tons of cast iron into resin bonded sand
with great results, and super detail. A couple of ceramic shell molds were
put in the line too, worked fine.
There is a high temp plaster like material for platinum sold by jewelry
suppliers, might work.

What type of resin, ratio to sand and do they last more than one pouring?
