The archetype of a bowl: a half sphere. Problem with half spheres: they tip over. That’s why we usually add a rim to the bottom, of flatten the base.
This bronze bowl by John Pawson, the famous minimalist architect, is that perfect hemisphere. No flatness on the base that disrupts the smooth curve of the profile – but this bowl can still sit perfectly upright or slightly tilted, thanks to hidden detailing inside the material (I would guess a number of strategically placed weights inside the material).
Pawson made his perfect bowl as part of a series of ‘5 Objects’ for When Objects Work.
