    I have about 800 ceramic molds made of plaster of paris.
    These molds are spent as far as ceramics use.
    I was wondering if anyone knows of a use for old plaster of paris molds.

    I had thought about using them as a heat mass in my garage. Maybe use my salamander heater to get them hot then let them give off heat for several hours while I work in there.
    If I stack them in the shape of an oven or igloo and let the heater blow in the center for an hour of so until they heat up a bit.
    Anyone ever seen anything like this?

    Never mind I just read the molds will re-calcine when heated to high temp leaving me with a plie of plaster.
