No, this is made in the the recent past and is not real yixing clay. Also, the colour is artificial colouring and is not safe for drinking. I would recommend that you do not use it to make tea. There are many such teapots selling on China street markets.
I left it to soak in tea when I just got it, I already suspected it was a fake when the blacks visible in the pictures turned to a sickly white after a night of soaking. At least i wont ever make that mistake again.
