help identifying my pot; BT mark and sun / sunrise mark

Hi, I'd be very grateful for any help from forum members in identifying this pot, which I was recently given. Many thanks, Maria.

Very strange. those multiple stamps look like "BIT" upside down???

Hi. They do - or maybe just BT with a dividing mark between the 2 letters? It's odd, isn't it.

It looks like a yunomi. An un-cropped pic of the whole pot will help, also an inside view.

Thank you. Funny you should say that - it's going to be pressed into service as a tea/coffee bowl, but it has a crack, and I'd like to know as much about it as possible before I decide if/how to go about fixing it to make it watertight again. How do I post additional pictures, a separate post? Sorry - I'm not great at using forum platforms.

Yes go ahead, just do another post, Servimg limits us to 3 pics per post unfortunately.

It does seem to be BIT but maybe that was an error when they made the stamp. Likely to be a BT monogram. I suspect they were just trying it out, hence the multiple stamps and it being upside down.

Hi, as discussed in comments on my first post, these are 2 more images - one un-cropped, and another of the inside.

The bowl is 8cm tall, and 11cm wide.

Thanks again everyone.

Maria.
