    Yes, you can.

    Can you give me a detailed answer on what I need to do after I finish hardening the casein plastic?
    Community Answer
    Not much do after hardening it. You can paint it after hardening, but you must shape it before you harden the casein.
  • Question
    Is the casein plastic edible since it is milk-based?
    Community Answer
    It is, but that doesn't mean it will taste good, or that it won't be a choking hazard.
  • Question
    Are any of these stretchy?

    Probably not because it is really hard. For it to be stretchy it has to be soft (and it shouldn't be soft).

    Yes, if the detergent has borax added, which it usually does. Using plain borax works best as there is a minimal of ingredients added.

    Can I sculpt things with the polymer plastic?
