Pottery Teapot Crackle Celadon On Interior

Appears to have been made in mold. Wonder why that celadon glaze on the inside when you won't see it much. I like the exterior finish. Recent, maybe Asian import?
Thanks

 

Hi,
It is glazed on the inside so the tea would not seep through the unglazed outside.

Actually, the exterior is glazed but not sure what do you call this type of glaze. The bisque seems like high fired porcelain/stoneware and looks nonporous to me. Similar crackle celadon is usually seen on the outside or both exterior and interior but I've never seen it applied only on the inside ( well, beside the finial).

 

The style on the handle looks Asian to me. I agree it's strange to see the celadon on the interior. Based on the exterior glaze I'd guess fairly recent. I don't remember seeing that bisque type finish much before 20 years or so ago.

I am not sure if the exterior finish is type of glaze or just part of the bisque. The paste is white but maybe it changed color during firing or the surface was just colored/treated somehow.
The sandy/gritty texture reminds me of yixing clay, like the lighter Duan Ni. However, I've never seen a combination of zisha clay and celadon. Plus, a teapot with yixing clay is supposed to have its interior unglazed as the clay gives flavor. Unless the piece is a water or other liquid vessel or so.
