Homemade Greensand for Sand Casting

In this video, I describe how to make your own greensand for casting metal parts. I also demonstrate the physical properties of properly tempered greensand.

Good work mixing all that by hand. It could be quite relaxing if my mind got distracted enough.

Thanks, I agree. This is only enough to fill my 10x10x2.5" flask. I have an additional 3 cubic feet of it in the garage but I'm sure you understand why I don't temper more than I have to, relaxing or not! :D

Looking at adding a small foundry to my workshop. I've read several articles about making sure the sand is moistened to the correct consistency. Your video was very helpful in demonstrating just what it should look like. Thanks for sharing it.

How do you grind up the kitty litter?

How frequently does greensand have to be replaced? I would imagine that the silica would fuse from the heat of the molten metal over time.

Get a cheapie hand mixer--use that for mixing/blending/tempering/mull­ing your sand.
