Soliflore bottle vase in stoneware with herbarium decoration

Here is a very pretty vase, a bud vase, or simply a decorative ceramic piece, with a beautiful, slightly bluish-grey glaze on the upper half, leaving the rest in raw stoneware, and a delicately incised floral umbel design. I find this ceramic very poetic and soothing. It's a lovely piece of craftsmanship, but I haven't been able to trace the artist, as the ceramic isn't signed (or perhaps the signature isn't visible, which is possible on slightly grogged stoneware; sometimes I think I can make out a few letters at a certain angle of light, then I tell myself I'm imagining things). The base is heavy, so it will be a very stable vase, which I will reserve for a few dried flowers since the interior has been left unglazed. This vase is in perfect condition, with no cracks, chips, or even a single nibble. It measures 17 cm in height and 7 cm in diameter.
