Ceramic pot cover with vintage scarifications 50s

The ceramics are in very good condition. We can see in the photos some micro-gaps on the outer edge of the collar, which are not really due to accidents, but rather to friction and use. No cracks, no splinters. The ceramic is glazed inside, with a very beautiful glossy green enamel, while the exterior is matte-glazed, very dark brown, and textured decorations of scarifications. The piece is elegant, it is a production of the 50s, probably belgian, but it is not marked.
