Clay molding

[thewise1]

I'm trying to figure out a nice way to vacuum form a case. Basically out of clay, it mostly worked last time, but making it by hand is tough. I was wondering what kind of home clay I would be able to use to keep molding and smoothing until it's close to perfect and still cure over a couple days. Maybe like bacterias modeling clay.

Hmm, I'd have to ask my dad about this. He's a ceramicist.
