This bowl is clear glass that I think has been flashed with blue on both sides (for certain on the outside, but less sure of the inside). The outer surface has been cameo-cut (I think this is the correct term?) and gilded, whereas the inner surface is gilded only. The effects give a very three-dimensional quality, which has not translated very well in the photos. Diameter 205mm, height 55mm. I would be very grateful for any information about the bowl.
