Bag-shaped vase, signed

Charming ceramic vase with a beautiful glaze in slightly pyrite milky gray tones and a very original shape, a bag shape. It is a beautiful and surely long artisanal work of modeling and glazing which has a signature underneath, but which I have not yet managed to identify. It is in perfect condition, no cracks, no chips, not even a chip. It measures 17.5 cm in height, approximately 16 cm in width and approximately 9 cm in maximum thickness.
