A late 19th century iridescent art glass vase. It dates around 1890 and is at the start of the Art Nouveau influence. The glass is quite finely blown and has a trefoil rim with optic rib sides. The surface finish is iridescent showing soap bubble type colouration. It is hand blown and the pontil has been ground and polished out. This particular style was a feature of late 19th century art glass in the Birmingham and Stourbridge regions, with some production also seen in the Bohemian region. This example is unmarked which unfortunately is the norm for glass of this period making tracking the factory problematic unless the design is referenced.
Light period wear. Some crystallisation of the finish around the upper shoulders and upwards, perhaps intentional.
