Hello Peter,
I have this blue & white vase...it is slightly bent out of shape, has a glossy new look about the glaze,no crazing, but has the black holes & some black blemishes on the blue glaze in places.
Is this a FAKE & if so, how old a fake & could you explain how can you tell?

thankyou,Stewart.
