Have you ever seen any other piece with a lotus this shape? I have seen similar decorations on yuan and early ming ceramics but I am not expert enough to say.
This would not be lotus. But apart from this, I'm afraid this is not antique or it is not Chinese.
Thank you Peterp. I had in mind yuan or ming because of the swirls on top and the double cercle inside were common in ceramics of the period. The swirl on the bowl I showed you are almost the same as the swirls on known yuan pieces. But its true, the colors and shape are different
The base is not old, and the blue color is too light - in a way that is usually found on more recent items which are made to imitate Ming blue. The shape of the outward bent bowl rim is also exaggerated, in my view.
