Featured Celadon vase

Any help with the mark on this 9" / 23cm vase would be much appreciated!

 

I don't know...but those characters seem Korean, to me...somehow.

 

The celadon looks Korean to me too.

 

From AI on Google Lens:
The image shows two Chinese characters, 志光 (Zhìguāng), which appear to be an inscription on a piece of pottery. This type of inscription is often found on celadon pottery, a type of ceramic with a distinctive green glaze that originated in China. Celadon is highly valued for its jade-like appearance, which in many Asian cultures symbolizes good fortune and prosperity.

Also from Google Lens there is this Japanese pot with very similar marking: https://www.facebook.com/groups/1333714019977227/posts/9730055387009673/

 

Pott-If the lingo is Chinese,you might ask the gracious Mr. Nagy on Asian Art Forum-he's the one member who generally (?) responds.
Our friend @wlwhittier has had good luck with him.

 

Thanks for those leads @kentworld! I sure appreciate it.

Thanks @bosko69 -- that's a good idea. I got into a FB Asian ceramics group during the last antiquers 'shut down'... I might post there too.

 

Worth a shot. Personally I'm rather useless.

 

Au Contraire, Dear Lady!
