No, this is all one piece of wood. The centre is not actually a bowl, it's domed, just in case anybody was wondering. I had the turned shape lying around the workshop for some time before I could make up my mind what to do with it, so this is not actually from a design, this is the result of just letting my intuition flow.
I think I'll leave this one as it is, and try another one, very similar, but with an orangey colour scheme. That should suit the ash wood a lot better. And I think it also needs to be brighter, something several comments are referring to and I do agree with that.
