There are many like it. But this one is mine.
Finally, a personalised Yixing zisha (宜興紫砂) teapot, made from zhusha (朱砂) clay. Inscribed on the bottom of the pot is the time it was made, followed by my name in Chinese.
As it appears, zhusha exists in a few subregions in Yixing, but it's apparently not as readily available as it was in the past. This teapot is fashioned using zhusha mined in the region of Hongwei.
I don't yet have details about the firing; I'll update when I hear from the potters.
