Yxing teapot...bought at a antique/junk store...I think near Lone Jack, Missouri. It is a typical Yxing teapot, made with red clay, unglazed (inside and out). The flange on the lid, is a good 3/4 of an inch tall. No falling off there!
The pot itself is 2.75 x 5.25 x 4". The lid is about 1.75" tall. I also has a hole right through the center (and the knob) for release of hot air. I never noticed until I now that the body of the pot is slightly larger towards the front...slanted towards the back.
There is a chop mark on the bottom. Needless to say that I can't read that.
