Well the description of the item says something like
Currently known best for their lighting, they were a producer of vases in the 20's - or something along those lines.
So there is an acknowledgement that if you search out the Noverdy name you get lots of Art Deco lighting and no other vases in this vein. Also there is nothing in Cappa for Noverdy.
The translated description of the item using Google translate to automatically translate the French is
'Thick smoked glass vase, with two strong handles, decorated with three red spots enamel powder, white, green, black and yellow, orange, blue, and yellow, red, blue and a cracked network part above. Currently, more known for its lights, the establishment Jean Noverdy installed in Dijon in 1920, notably made vases. The clean, geometric lines are characteristic of the Art Deco style in which it usually works. The huge spherical base is topped by a short neck, formed in continuity, which relate to two broad flat handles curved V. Jean Noverdy uses the juxtaposition of bright colors, also typical of this artistic movement, appeared between 1920 and 1930. Two thick layers of smoked glass trap powder multicolored enamel. Except, the color white, it uses only the primary and complementary colors, from their combinations. The colors yellow, red and blue and up the first spot. The red, green, purple and white, and yellow, orange and blue, respectively, are the other two. A cracked network also runs the upper inner surface of the two-thirds. (Small, 2005)That is
so close to the three vertical bands of colour done on mine, and the way the spatter and spots look on the piece as well as the colours used on mine, and imho also on the others in the same vein as my vase. The only difference being that on that particular vase linked to apparently by Noverdy, the crackle is only in the top two thirds of the vase. Whereas on mine and Dirks for example and the other two I found that were signed (I did not see the signatures but they were both described as being signed), the crackle is over the whole vase.
Whichever way, alarm bells are ringing for me
I have to say I'm slightly suspicious they have their description of the maker wrong - for whatever reasons that could be. It is not unknown for a museum to have an incorrect description.
