Antique Art Deco vase 1920-40 in fine stoneware, Art Nouveau and Chinoiserie style

Very fine antique vase, 1920s-1940s, possibly mid-1930s. Unsigned, in fine stoneware biscuit (or possibly porcelain), in a style combining art nouveau and chinoiserie. Handcrafted, thrown, stamp-decorated and hand-painted, with enameling only on the interior. Pot-bellied amphora shape resting on a small, slightly raised round base, narrowed neck and flared spout, fitted with two double handles in the art nouveau / art deco style. Unglazed exterior, matte beige biscuit texture, stamp-decorated with dark Payne blue borders and Chinese-inspired floral and geometric motifs, close in places to a paisley pattern, gray/black painted filling in the petals and on the leaves, black painted borders and handles. Metallic brown-black enamel interior, reminiscent of certain Belgian productions from the interwar period; the shape of the handles, the material and the technique suggest European manufacture. The chinoiserie-style decoration here is misleading; it is most likely not an Asian production. This vase does not come from industrial or semi-industrial mass production: a slight deformation of the neck highlights manual shaping. Unusual and rare object, very decorative, probably from Belgian, French or Dutch production. Height 25.5 cm, width 21 cm at the handles, maximum diameter 15-16 cm, diameter at the neck 10 cm, weight approximately 1 kg. Perfect condition, nothing notable, some small discreet stains, visible use inside but not very marked.
