Outdoors or in a well ventilated area while using a sand blasting box and proper protective equipment of course??? Has anyone tried that? I would like to now how they compare to sand, pecan shells, baking soda and that sort of thing. It would help to know. Thanks a bunch. Be blessed,

First off, I have not tried this and am only openly hypothesizing. Eggshell only rates around 3 Mohs on the hardness scale and fragmentates easily. I could imagine it would be useful for soft blasting purposes if you could get enough of it.
