It's extremely hard to generalize about pots made in different periods. Not only does the clay change, but the techniques of clay preparation before its ready to be used, and the firing temp and time, will differ from kiln to kiln. There are perhaps millions of Yixing from the 80's/90's. The idea that all of them are too porous doesn't make sense from my experience. There are definite differences between pots and the fun is to find ones that suit your taste. To write off those millions of pots because of the handful that you tried and didn't like is a bit of a weak argument, don't you think? Some potters are better than others, too. Many of the masters that broke off from factory production still produced outstanding teapots. Trying buying one of those if you could afford to and if you could find one. However, we don't have to go in that direction to find a good 80's/90's pot.
Thank you for your post, Tead Off.
Maybe I wasn't clear enough in my past posts, my fault.
When I said " I always found (mid-late 80s / early 90s) teapots to be too much porous", I was in fact referring
only to factory teapots, made when they were operating, especially those made in F1 and F2. I
never made any reference to Yixing teapots made from privately owned kilns (of any age), for the simple reason that I have no experience with them.
I think you are exaggerating a little bit with the number of
factory Yixing clays available and used at the time. For example, F1, from the opening years up until the early 80s (this is IMO the golden period for quality clays) used probably no more than 30/50 different Yixing clays (if someone has numbers from trusted source, please share), maybe even less.
Sure, they changed over time, especially when a certain typology of clay finished completely and was replaced by a new one, e.g. Hongni from the 70s replaced the very same Hongni from the 60s because depleted completely.

OTOH, I'd bet a lot of the factory 1 production from CR period were not particularly well made or even fired evenly every time. IMO, consider yourself lucky to find any pot from post war to present that fulfills your ideal of 'perfect'. But, if you are only looking for old clay and think that it is the difference maker, then pre-80's is the way to go because they did use pure stuff for the most part. Just my 2 cents.
I must say I never saw a bad fired factory teapots made from the 70s onwards, while I do find sometimes not so well fired factory teapots from the 60s; but even in this case, if you have a good eye and the teapot in the hands, is really really easy to tell if the teapot has been fired well or not. Different matter for ROC and earlier teapots, it's somewhat tricky to find well fired teapots; easier with Hongni and Zhuni ones, almost impossible according to my experience for Zini and similar ones.
