Colorfull glass vase soliflore in the style of Delatte

This vase has wonderfull colors; deep orange and reds contrast with dark blue working its way up from the bottom and becoming litlle speckles on the top. The vase is not signed. A small 2mm chip on the top (see picture), otherwise good condition taken into account its age and use. The neck of the bottle doesn’t appear to be entirely straight, depending on how you turn the vase around (see 2nd picture). Probably French, in the style of Delatte. 44,5cm high.
