Id luster glass porselein sugar pot

This pot is about 16 cm long and 12 cm high.

it has three rings which is difficult to photograph. bottom ring ends where the purple orange brown color starts and third ring ends where the top part of handle. see futile attempt on paper


it has an imprinted brand/decor number? 100


It has a art deco era look but maybe earlier?
Any info abouth age and origin and the maker is most appreciated
Thanks for looking,

 

It may be porcelain, it's not glass.

 

Luster glaze - not made of glass. Appears to have a faintly impressed mark of 3 numbers on the bottom?

Cheerful colors!

 

yes the number 100 is impreseed

 

Thank you @i need help .
the color use and the shape with 3 circle reminds me the art deco era. Also lots of 1920 Japan lusterware porcelain I found on the web. Also the picture of these glaze vases i found in the book you mentioned above.


but you probably right its probably not art deco, but Any idea where and when its produced? Begin 2 or late 20 century???
