PETER COULD YOU TELL ME HOW OLD THIS COPY OF A STEM CUP IS ?

Hi Peter,
I guess the pictures speak for themselves.
The porcelain is translucent.
The bowl is distorted.
The underglaze copper red has black/grey/green patches breaking through the surface of the clear glaze coating...could these have been intentionally placed?
The glaze bubbles are of mixed size & do include some copper in the bubbles.
The painting is hand brush work.

What I find odd is that the clear outer glaze is dusted all over with tiny black speckles just under or on top of the glaze...is this normal?
How old a copy could this be.
regards again,
Stewart.

FURTHER IMAGES OF STEM CUP

I am sending you further images of the interior of the bowl.
There appears to be what looks like a few glaze flaws with some embedded foreign material.
Could this be ash also?
or an attempt at manipulation?
any further information would really be helpful.
thanks again,Stewart.
