Bok steanze Thank you for sharing!
Would it be correct to say that the 4 character Zhongguo seal first appeared only sometime during the Cultural revolution (after 1966)?
Is there any information as when did the different 6 character mengchen seals of 60s (and earlier) ended?

As far as I know, some are being used until now : )

Every seal that was used yesterday can be used today or tomorrow but that doesn’t really answer the question of when F1 ceased using it. I could be mistaken but I don’t think any of the 6c seals from pre-F1 to 60’s were ever used by F1 again.

@Chadrinkincat of course…

If I’m not mistaken some 6-character seal were used again in the 80s, but no idea when they stopped altogether to use them officially.

I have a 6 character mengchen chop with guava shape from green label. I am not sure from 1982-1985. Most of the info I found indicate that after 1985, artists started using their own name or surname on their chop.

That is some nice looking clay...

Haha I am not sure if it can match the 70s qingshuini or other zini from the green sticker period.

Yup, a project for another day. BTW, @Bok, do you know if black star clay existed before 1980s? I read it was produced to satisfy the Taiwanese market around 1982. Other source I read said late 70s already have black start clay, and the color looks like qingshuini with black dots. Any thoughts?

@DailyTX no idea. Not too much into the peculiarities of Factory clays. So much nit-picking about this or that batch… can’t be bothered

My very limited contribution to the topic: my 60s hong ni biandeng and my (80s, I assume) green label guava (qingshuini, I assume).

The green label one looks pretty sloppy in comparison to the 60s one.

I thought I read somewhere around here that six-character green label seals were 80s, and others could be 70s, but I may well be wrong.

But I also assume that the original question was really about whether there was a break in the usage of the six-character seal from the 60s, and if so, when, as to which I know nothing, and as to which look forward to learning from others here.

@Bok
I wasn’t paying much attention until I encountered a few black star clay teapots
With different color tone. I guess this question will be tuck away until I find more info later.

That's a whole different story

Yes, that would be correct. Seals similar to the 6 character nan meng chen and hui meng chen are already seen in ROC, then in F1 they are used until about 1966, afterwards 4 char ZGYX are used until about the end of the 70s, in the early 80s you start seeing some 6 character hui meng chen seals again (but no nan meng chen seals), these 80s hui meng chen seals look different from the ones in the 1960s.

To my knowledge black star clay is only produced since 1982. I have never seen black star clay earlier than that... Does the other source have some pictures of 1970s black star clay teapots? I would be very curious to see them.
