This pot’s clay is weirdly spotted. Mark is Wu Desheng zhi, with Wu Desheng being an outfit during the Republican period that made pots. 165ml.
Not all yixing pots were used for tea brewing, or at least that’s the way it seems sometimes. In things like senchado sometimes they were used for water cooling/pouring rather than tea making. It’s not always clear to me why one is designated as water dropper rather than teapot. When there’s a pair sometimes one gets assigned one job and the other the job of tea making. In any case, this pot is called “zini suichu” which literally means purple clay water dropper. 145ml.
This pot is one of the ones I use most heavily. I got this for a song because its handle was glued back on, but the gluing job was obviously very well done and there’s been no problem. The lion is quite detailed. The pot is stamped “tiehuaxuan zhi”. Tiehuaxuan is the name of a company during the Republican period making yixing pots, specializing especially in smaller pots (lion or shuiping) that have calligraphy and carving on them, like this one. They also make whole sets including pitchers and cups, but those get expensive. The seal under the lid is “Jiangji” referring, probably, to the maker Jiang Anqing who is known for making lion pots. 115ml.
Seals can have some pretty creative types that make them hard to read. This one is one such case. It’s hard to make out what the seal says, so my best guess is chenxi, but it could really be other things. EDIT: Someone who knows this stuff better than I do claims it’s changxi. To call this lid loose is being generous – it’s practically falling off. It comes in a nice wooden box. The words on it says “cannon spout” “white clay kyusu”. The box is from Japan but the pot I believe is a yixing. 135ml.
