aevai wonder if #plaster is oven safe, and how well it works with #polymerclay? might be useful for creating support surfaces for irregular polymer clay shapes, or an alternative to foil for interior structures
Krzysztof Sakrejda@aeva it'll dehydrate at those temperatures and become brittle and probably fall apart, regular clay might work better
edit: ... if you do use regular clay for this just make sure it's dry before it goes in the oven...
