Chinese Plate in Green Cinnabar?

I inherited this plate from my mama. It may have belonged to my paternal grandfather, who was known to frequent the "junk" shops in Manhattan during the 1920s-1940s. I have posted the plate on other groups and the only response was "it looks like Cinnabar". But cinnabar is read. Does anyone recognize this type of plate?

 

It looks like it might be plaster because of those chips. Pretty color. Id call it cinnabar style .

 

Cinnabar most often refers to the mineral used to color lacquer - traditionally mercuric sulphide, which is red. But lacquer can be colored with other pigments. This may just be an example of green lacquer, carved like the more typical red lacquer. But lacquer work was usually done over a wood substrate, or sometimes a papier mache like material. I would not expect to see the white material visible at points of damage as johnnycb09 has also noted. So it might be plaster with a coating trying to imitate a celadon glazed ceramic.

 

Thanks - that's the most definitive answers I've seen

 

Any idea what decade this might be from?

 

No, sorry. But my guess would be not too long before your grandfather may have acquired it.

 

Pressed plaster. No collectors would buy pressed.
