Vase "lens" or "gourd"

Charming little ceramic vase with rounded and fluid shapes and soft colors, in blue and gray tones. Its shape is relatively original, it is round in one dimension and rather flat in the other dimension, this is called the "lens" shape. A bit like a gourd that we would wear on the belt... I also wonder about the shape of the base which has a hollow in the shape of a half-tube... To put it on a tubular support. A rope. If you have any answers, i'd love to learn more! It is in good condition, neither cracked nor bright, just a little stained under its base. It measures 19 cm high, 13 cm wide for a "thickness" of 7 cm. It weighs 325 g.
