www.great-glass.co.uk Hi, Lorraine
You are right in thinking that the engraving on our blue vase (attached photo 6234) was very similar to that on your vase. At the time we attributed it as 'possibly by Stevens & Williams', though we had no hard evidence to support that. Since then, we have also had an amber bowl (photos 7844 and 7844s) with similar birds, but amongst fruiting grapevines. More recently , we had a blue powder-bowl, and an amber cigarette-box, both with the 'bird in rose-bush' engraving on the lids. The cigarette-box still bore an original paper label 'Verrerie Artistique, Cristal Palace, Vichy' (probably the retailer, rather than the manufacturer), which at least shows that this type of glass was available for sale in France.
Given the appearance of this glass in several countries, the style of the engraving, and the constant repetition of similar 'bird in bush' patterns, we now think it was probably the product of a small Bohemian glass-refiner (the Bohemian engravers excelled at this sort of thing), who found the 'bird in bush' theme to be a popular one, and exported it all over the place. We are fairly confident that it dates from somewhere between the two World Wars, the 1920s or 1930s.
If you should ever find any better proof as to its origin, please let us know!
Best regards,
Philip & Ann Petrides
