QIANLONG SIX CHARACTER MARK, HOW OLD REALLY ?

by Andrew

Hello again to you all,

I have a large apple green cracle glazed vase with this hand written mark on the base, possibly in black, cannot tell for sure.
An oriental porcelain expert told me that Qianlong marks like this, written in black over the top of the glaze where used on porcelain made in late C19th all the way through to now & surmised from my pictures that the vase was about 20 years old.

The problem is that the mark is actually under the geen crackle glaze & not on top...does this make a difference to dating?

Also I have a copy of the book, Oriental Ceramic Art, by the well known authority S.W. Bushell...in where he describes nearly perfectly fish roe crackle green porcelain, right from paste colour, turning form, shape & glaze with pictured examples as well...mine seems to fit nearly all the characteristics in that book.

In saying all that then, do I have a high quality reproduction vase with fantastic old age tecnique & materials that are near exact to Qianlong Period monochromes, but still made about 20 years ago?

Confused on this one also!
any help appreciated, as I still would like to collect in this field, but I feel disheartened by conflicting opinion & from making further purchases in the future.

regards to all & I wish you all smoother sailing in these waters,
Andrew
