There are images of 4 vases in my book, the one I have not mentioned yet, is a round shape with crysanthemums on a ribbed background. There is an amber example in the museum.
Those 4 are all there are in this "range" of satinated vases from this maker, in the museum itself and in the book from it. Although I did not see or photograph the "Les Nuages" style one which is in the book, it wasn't on display.
I've found an image of the crysanthemum one on the web, (on pinterest which I don't understand) described as;

I'm only dabbling around the edges of this, Jay - I don't know nearly enough background to be able to contribute. I just felt when I was in the Museum that I really ought to get records of these particular vases and their attributions.
