The popular IG vendor Yinchen has a website now, and has posted some detailed info about each of the clay they use, including mine, pic of original ore, firing temperature range, shrinkage rate, and photos of test tiles fired at different temperatures.

I'm not in a position to speak to the veracity of all this info, but it's interesting to see this level of detail presented on a retail site.
I have never purchased anything from them, btw.
I had quite a few conversations with Gao from Yinchenteapot, he gets the info from the book "Yixing Zisha Mineral" written by Zhu Zewei (宜兴紫砂矿料 by 朱泽伟) which is Standard used by Yixing potters for looking up information about certain clays, and their attributes. I cannot recommend enough this book to anyone who is interested in Yixing teapots, as it'll clear up many misconceptions which are common among the western audience. I plan to translate the book to the best of my knowledge for the western audience, however I lack the necessary knowledge in geology and material science, to not make mistakes during translation.
This is also the same book Charlie recommended from the old days, on Teachat.
I haven't purchased anything yet from Yinchenteapot, however I plan to commission a bespoke teapot, and will get back with the results.
