anyone ever use polymer clay, or modeling clay in a ceramic mold? How would you prep the mold?
I was given several ceramic molds for making "mushroom canisters" I only want to use the "top" to create a variety of mushrooms for my garden.
the tops range in size from 3" to 11" wide and are about the thickness of a heavy plate. There are six different sizes in all. The "tiny shroom knob" is a seperate piece, so I would have a very realistic looking mushroom cap. The stems will be easy enough to create on my own.
Does the clay need to be sealed to stand up to weather changes?
Other suggestion are welcome too.
