Looks like a nzwh style coated plate with marks reminiscent of what you’d see from accidentally scraping a wall with the plastic the part of roller durning painting.

Thank you. I am still trying to figure out which among the various surface irregularities and texture variations that one can see on some older pots are a "wind glaze". Unfortunately there's not much information on these things in english.
It is not super clear from the photo, but it's green label QSN plate, no coating (here's the other side). It's the actual clay. It looks as if the clay was pulled or smeared during the forming of the plate, resulting in a different texture after firing.Chadrinkincat wrote: ↑Wed Jan 22, 2020 9:02 amLooks like a nzwh style coated plate with marks reminiscent of what you’d see from accidentally scraping a wall with the plastic the part of roller durning painting.

You should assume, that from 1980 all teapot has Barium carbonate added to it, in a random amount.
Wind glaze can be a sign of the teapot not having Barium added, however not having wind glaze on the pot, doesn't mean it has Barium in it.
Mathematically:
Wind glaze => No Barium Carbonate
(the reverse is not necessarily true)
Ah, ok! Thank you! It’s funny how a “fault” can indicate something good.Youzi wrote: ↑Thu Jan 23, 2020 1:06 amYou should assume, that from 1980 all teapot has Barium carbonate added to it, in a random amount.

There are many other "faults" which are indicators of a good teapot, in ZishaBaisao wrote: ↑Thu Jan 23, 2020 1:30 amAh, ok! Thank you!

I have got another riddle for you:
Last week, I bought a small set with 3 cups and 1 lid which has a green label sticker on it. However, the different type of clay made me suspicious. After some research, I now think that the lid is from a different cup. I even found a similar photo in the Facebook group which supports my assumption. What do you think? It was a bargain, and I needed a new cup with a lid for my sugar. So I do not really care. But it would still be nice to know.

I experienced this once that the clay on the lid was old while the pot body was new. The two color tones looked alike in dim light. The seller only posted a close shot of the lid. By the way, the sticker on your lid looks odd...Mark-S wrote: ↑Fri Jan 24, 2020 3:03 amI have got another riddle for you:

The cups are definitely not brand-new, because they already have a patina. However, I personally do not like the clay much. Difficult to say how old they are. Regarding the sticker: I don't think that it is a fake. It's probably just the picture. However, I will compare it to others on Monday.
@Chadrinkincat
Nice, you can even see a sticker on the lid. Where do you find these images?

They do look like they have patina, what got me thrown off is the sticker looks quite new. Unless they purposely saved the sticker and glued back on just for sale. The mystery will have more clues when you are holding itMark-S wrote: ↑Sat Jan 25, 2020 9:22 am@DailyTX

I’ve got pictures of the F1 catalogues save on my phone for easy access.
Much of it is available here too.

That lid is different clay. Zini/qsn lid while the cup looks like neiziwailihong/zini coated red inside out or possibly hongni but seems less likely

I am increasingly fascinated and intrigued by the European faux yixing pots, such as those produced by dutch potters in late 17th century

and also by the red stoneware of Boettger and others

Some are pretty convincing. I wonder what material and processing they used.

Yes! They are fascinating indeed! I think especially the early period of imitations is very interesting.
If I understand it correctly not a lot of it survived to this day. The clay seems to have been something which is nowadays more commonly used for floor tiles.
They only produced those for a relatively short period, passing then on to porcelain
