Besides, I wasn't limiting myself to transportation. Pottery wheels need to be heavy (store rotational energy) and as close to a perfect disc as possible to minimize the wobble that any other shape would inevitably have. Mesapotamians had stone pottery wheels although I have no idea how 'perfect' it was. Anyway, this thread's wheels are going off the rails (ha ha) and needs to end.
