problems i ran into and what i would do different next time:

At first I really loved how it was going but I made the mistake of putting the clay directly on top and in the plastic flower dish, once it got leather hard I couldn't get it out so I had to destroy it and try again. So the 2nd time I put a layer of parchment paper in between the flow dish and the clay. I'm planning to glaze it with a glaze that has the colorful bursting crystals since I've done that twice before and I love how it turns out.
