Yeah, I said sand, but dirt may be better.  You may also be correct to let it dry and harden some. I know [http://www.amazon.com/Sand-Casting-Concrete-Five-Projects/dp/0764328670 sand casting] has been done by others though, so it should also be possible to use sand.    --[[User:Crasch|Crasch]] 06:25, 4 August 2008 (UTC)

In the reference he uses dirt instead of sand for the mold. I think dirt would hold its shape better and make a better mold. Probably be good to get the dirt wet, make the right shape, then let it dry and harden some. One of the ferrocement methods is to make a mold for an upside down boat out of wood and then put on steel, then plaster. Put you have to work in the plaster, probably with a vibrator. Anyway, not sure sand will work.Vincecate 02:16, 4 August 2008 (UTC)
