All that mixing had introduced bubbles, so we had to tap the molds for a few minutes to encourage the bubbles to rise away from our precious plaster emblems and pop at the surface.
These were supposed to set up for 24 hours before we use them, but my son was impatient and he attacked his after three hours. It was set up nicely. So I started peeling the foil side of the pie plate away from my new rubber mold.
I kept peeling and even peeled the foil away from the hot glue that held it to the plaster.
And then I pulled back on the rubber edge a little, and it separated pretty easily from the plaster.
