Can you bake already painted plaster wrap?
It's a simple question really. I've made something consisting of wire & foil on the inside for structure & plaster wrap on the outside. I'm in the process of staining it with tea & after that I'm going to want to paint it with acrylic paints then go over that with a glossy coating. Is all of that possible to bake & if so at what setting & for how long? Or is that not possible? Not really used to using this kind of stuff & am learning as I go. Anything helps, thanks.

Why do you need to bake your item if the plaster has already *set* (it doesn't "dry"), and if you're using *permanent* paints and permanent clear finishes? (Hopefully you waited till the plaster strips were thoroughly set before painting.)
(Permanent paints would be acrylics and latex or most any except poster/tempera paints, watercolors, and "washable" paints. Most clear finishes are permanent.)
You could bake the whole thing if you really needed to when finished with the painting and glossing (or just use a paint that dries with a "gloss" finish), but you probably wouldn't want to heat the plastics (paints and finishes) very hot or very long, say 225-250 F for 15 min?, in case they start to darken or even bubble. You'd need to use an oven thermometer though because many ovens don't heat to the temp set on their dials, even after preheating.
