Plique-a-jour Vessel "Spring and Autumn"

“Lost-base” plique-à-jour

“Lost-base” plique-à-jour (shōtai shippō) is prepared following the same steps as wired cloisonné, but at the end of the process the copper vessel is dissolved in acid, leaving behind only the enameled surface. The Japanese term shōtai means “omitted base.”
