    Expert Answer
    Yes, and chocolates are a great example! There are molds that are specifically designed for shaping melted chocolate into fun or fancy designs that you can eat. They're usually made from food-safe materials like silicone or hard plastic, so they're safe to use with chocolates.

    What can I use as a release agent?
    Community Answer
    They sell mold release sprays at many craft/hobby stores as well as industrial/hardware stores. Search 'release agent for molds' to see the selections available. Some have also found success using mineral oil or some form of cooking oil (like vegetable oil) but these should be used with caution as they may have an effect on certain materials not curing properly.
