Still Life with a Porcelain Bowl and Nautilus Cup

This 1660 canvas from the Thyssen-Bornemisza family collection — distinct from the museum collection — represents Kalf at the apex of his pronk still-life production, combining a porcelain bowl with the nautilus cup that had become a near-signature element of his most celebrated compositions. The nautilus cup was the seventeenth century's quintessential object of wonder: a nautilus shell, polished to reveal its iridescent nacreous layers, mounted in a silver-gilt stand by goldsmiths whose craft transformed natural marvel into luxury object. Kalf's repeated return to the nautilus cup across his career suggests not only its commercial appeal but a genuine painterly fascination with its optical complexity. The Thyssen-Bornemisza family's dispersal of their collection across institutions and private holding created separate lines of ownership for works of equivalent quality, and this canvas represents a significant segment of that holding.

The nautilus cup's challenge — rendering the iridescent shell in oil paint — required Kalf to build up thin layers of different coloured glazes that create interference colour effects suggesting the actual optical properties of nacre. The porcelain bowl beside it presents a contrasting challenge: cool, hard, matte white with printed cobalt blue decoration. Managing the visual coexistence of these two very different material surfaces within a single tonal scheme is Kalf's technical achievement here.
