Light blue monochrome

[T. Chan]

Dear Peter and All,
Here I post a light blue monochrome vase. Could anyone help me identify the period because I have no idea at all.
Thank you.

20th century. The foot rim has been subjected to age faking.

Dear Peter,
Thank you for your help. I know it doesn't feel ok to me It supposed to copy Ming period right? About the age faking of the foot rim, could you recommend a book or a link so that I can learn a little on base and foot rim? This definitely help a lot since I don't even have a book about these.
The brown foot rim I have used lemon and scotch bright to clean it but the color still there, so I think it is not a brown wash. All ceramics that I have acquired since 7 yrs ago until last year, I have cleaned with these. My friend said, don't use lemon cause it will wash the patina away(is this true?, but all the dirt go off easily. Cause before, I always thought that expert like to see the real paste rather than the dirt) so starting this year, I did not clean with lemon anymore. Thank you.

That is the problem...people think a brown foot rim means it is antique. In fact, under normal usage or storage, porcelain does not get this sort of brown foot rim. This is artificially made that way. I do not care of a patina on the foot rim. The consistency and density of the fired clay is more important than its color. Again, this sort of brown color is invariably a sign of age faking. Often it cannot be removed, quite unlike dirt.

Dear Peter,
Your comment is crystal clear! So in this case, the celadon "bronze" vase definitely a crossed finger too (Please have a look). About the density and consistency of the clay are new to me. Could you recommend a book regarding this? From Ming onwards, if any.
Thank you.
