### Book:

- Published [Book 2 - Chapter 8, Section 9: Duanni (段泥) Ore and Clay](https://www.teatechnique.org/duanni-duan-ni-ore-and-clay/).
- Edit to [*Book 2 - Chapter 6, Section 2: Developmental History of Yixing Mining*](https://www.teatechnique.org/developmental-history-of-yixing-mining/): the first sentence incorrectly read "Zisha ore has been mined and refined since the mid-**Qing** dynasty..."; this has been updated to mid-**Ming** dynasty. We apologies for the error, which was (hopefully) obvious in context of the chapter.

### Other Content:

- No Changes.

### Updates:

- Thank you to everyone who came out to visit me during the Chanoyu Week NYC 2023 Grand Tea Ceremony Event! It was wonderful to meet and whisk matcha for you.
- This has been a slow month for publication because of Thanksgiving travel and other interruptions; most of the team is stationary for December, so we should be back to publishing twice per month instead of once per month.
