Hi, I was suspicious that this vase could be a Webb bronze piece, since it has several characteristics known for Webb bronze:
1. It has bronze iridescence
2. It is on a green ground, and Webb bronze is called green bronze because of the green ground
3. It has a perfect round, centered, highly-polished pontil
4. It has a rounded rim
5. The decoration is etched (or engraved), and then infilled with gilding, which is one of the decors listed by Hajdamach
6. Some Webb bronze pieces have an Egyptian theme, like the one shown in British Glass 1800-1914 that has engraved and infilled hieroglyphics
Nevertheless, I am puzzled by the gilded number 1 in the center of the pontil. I tend to think gilded numbers are more prevalent on Continental pieces. If it were Bohemian, though, I don't know which glassmaker could have made it, since Loetz bronze glatt is on an olive colored ground, and Josephinenhutte used a cobalt ground for their bronze zypern.
Is the gilded number 1 a deal breaker for a Webb bronze attribution?
Thanks for your insights!
