Bluish glazed stoneware cut

Nice ceramic cut, sandstone it seems to me, enamelled (except on the bottom of the foot), in bluish tones. It seems to me that it is an artisanal work, because we notice some irregularities on the foot: irregular enamelling, a small round mark under the enamelling. It could be used as a coffee cup, as an original container to present a sauce or candy or to receive tips. It is in very good condition, no crack, no chip, not even a gin. It measures 12 cm in height, 8.5 cm in diameter at the top, 6.5 cm in diameter at the foot. It weighs just over 200 g.
