Any one come across this mark?
Cant find any.
???? means old kiln of Jingde(zhen). The last character is written in simplified Chinese, which means that it is probably from the second half of the 20th century.
Why do you people still try to date Chinese porcelain by the mark?
Many of us (novice) rely on marks for identification because we simply don't know what to look for to date chinese porcelain.
It is necessary to get rid of that notion when collecting Chinese antiques. I would suggest to read the article in the main site about why it is futile to depend on Chinese marks. This will save you a lot of time and money wasted on obtaining fakes and newer items, which have no collecting value at all.
Thank you both.
