I figure the most mold making is discussed in this section of Crafter. So I tried making a two part plaster of paris mold of a piece of tree bark (it's like a cave) but despite using silicone release spray on the bark side (I couldn't vaseline it well), it's pretty stuck in the plaster. I don't think I can get it out without either breaking the tree bark, or breaking the plaster. I'm going to have to break the plaster.

I don't understand what went wrong? Silicone release spray should have worked, shouldn't it? Even on wood?

Another problem is that the clay stuck in some parts to the plaster as well and I have to really scrape it off.

It could be because you're using plaster of paris. How are you planning to use the mold? Polymer clay, pottery clay, slip casting? If you're going to use it for ceramics, I recommend pottery plaster because it has a specific absorption rate that works really well with clay.
