Closed Form Bowls

Closed form bowls have an interior bigger than the mouth opening. While closed forms are not nearly as easy to turn as traditional open bowls, they are visually striking, especially since they work better with secondary art such as carving, painting or woodburning.

To look right, a closed form should be a bit deeper than an open-mouthed bowl. I like to think of the shape as a doughnut with a base, or foot, under it. Artistically, a doughnut shape (another analogy is an inner tube) is called a torus. A torus is generated by revolving a curve (or a circle) around a center point as in the illustration
