Just a Lemmy shitpost comment, don’t think about it too hard Sure fine sand and a runny plaster, ceramic capture detail. But you still bulk it out with rougher stuff to give the mold heft.
Maybe not cement. But I also wouldn’t recommend doing back yard casting for Life critical parts if you’re asking what your detail capturing materials should be and what your bulking out materials should be.
