I'm interested in creating two types of bowls. The first is relatively straightforward - in design, at least - as it will just be a large salad bowl. The second is going to mimic a bowl I was gifted recently that is more or less tear drop shaped.
My question is: how I would go about removing the inside (and outside for that matter) of the bowl? Would this process be the same for a bowl that is not circular?
Bear in mind that you're speaking to a beginner here. If possible, please provide the investment context, ie what are the low tech (cheap) and hi tech (expensive) tool options?
