It’s been a while since there was much of a clamor for Sèvres, the nearly 300-year-old French porcelain manufacturer that once produced tableware for the likes of Catherine the Great and Louis XVI, who famously commissioned the state-run manufactory to create a bol-sein for Marie Antoinette (yes, a bowl in the shape of a breast, nipple and all). Of course, tastes changed: As minimalism became the prevailing design aesthetic over the past couple decades, European ceramics, with their liberal use of gilt and decoration, largely fell out of favor, and auction houses have mostly scaled back on the category, except for the highest-value collections. But in the art world, there’s always an opportunity for enterprising dealers who think they’ve found an underappreciated market.
