Trim a wide shallow bowl foot ring

Wide, shallow bowls (pasta bowls, serving bowls) need extra foot stability because their center of gravity is spread out.

The challenge

• The foot must be wide enough to prevent tipping (wider than a standard bowl foot)
• But not so wide that it looks clunky
• The interior trimming should follow the bowl's interior curve

Test it aggressively

Set the bowl on a table and press down on the rim at various points. A wide bowl with a narrow foot will tip. Find the minimum foot width that makes it completely stable.

This is an engineering problem as much as an aesthetic one.
