Hello. I recently found this teapot and I have a few questions. Can anyone tell me what type of clay this is made just by looking at it? I get confused about these different types of pottery and their textured clays. Also wondering if this type of teapot without a handle has a name or indigenous to a specific place. And, of course, I have no idea who made it. Perhaps someone in the forum will recognize the signature or point me in a direction to find out. Thank you!
