3. THE CATENERY CURVE WORKS EVERYWHERE
The catenery curve notion works for rather flat bowls (above) and also tall vase forms as well. However, in the photo below, note how the sides of the hollow form head straight into the table. If these are the sides of a curve the bottom of the curve is well below the table. Though not necessarily heavy in appearance, the foot becomes very prominent and generally conflicts with the curved lines of the rest of the piece.
The hollow form below has a curve near the foot that closes very close to the support surface. When viewed from a slightly elevated angle, the foot isn’t visible and the piece appears to actually float above the table. How is that for lightness? Quite a difference from the last example.
