Ceramic potter's pot cover vase 50s

The pot cover is in very good condition, no accidents, no cracks. On the outer edge of the collar, a small hollow in the enamel, the size of a pinhead, but barely visible to the naked eye. It is a very pretty piece of pottery, which was turned, then glazed. Free-form, with a flying collar, and beautiful matt black enamel embellished with a graphic pattern with brilliant mint green foam, it is a refined ceramic, beautifully made. The interior is also matte black, and it is very clean. No traces of limestone. Made in france, probably from the south, dating from the 50s. The useful volume is not very important, because of the hollows and bumps.
