Re: Carving vermiculite
Mike, I use what are known as "ribbon tools" for carving vermiculite board and I also use them a lot on clay. On clay they are nice as they remove clay, not just push it from one place to another like solid tools would do.
Like these. You can use any router bits that are commonly used on wood on vermiculite board. It will make one heck of a mess.
I would suggest you make some by hand, get used to cooking out the binders, applying kiln wash and seeing how you like them before going crazy with the CNC router. After the kiln wash has been fired once they generally cast much cleaner if they have some mica rubbed into the pores of the mold.

HER last words were, "I'm melting, melting . . . " Dissenting opinions generally welcome for comic relief or personal edification. Sometimes both.
