I have a very basic question:

How do we measure pot wall thickness? Is it at the spout or at the rim?

Also, what are the mm ranges for:
Thin, medium and thick?

I am on the same boat as you, and have yet to find a metric. Something I noticed is weight of the pot in comparison to how much liquid it can hold can give you a rough comparison if you have 2 pots in front of you. This idea has a lot of flaws due to weight can be distributed on the handle, design, decoration, bottom wall, etc. This was a funny idea came to my mind while I was having dim sum with family and they were talking about the skin of dumplings

Thats an interesting idea!

@LeoFox @DailyTX

It comes down to what is the intended purpose of knowing the exact thickness of the wall?? I usually associate thickness or thinness of the wall to the weight of the overall pot. What I've noticed are super thin wall pots always comes with smooth or lightly textured surface. No elaborated designs and decorations that will weigh the pot down. So far the lightest pot I've come across is a 150cc pot weighing only 98g.

Cheers!!

I guess if we see it as a cc:dry mass ratio, then 3:2 would be super thin?


Maybe we can come up with ratio ranges for thin, medium and thick? Do we include lid?

Di Cao Qing might be my favorite zini clay so far. Its versatile and works well with aged sheng, liu bao and probably young sheng also.
I have a LQER coming from TWL, and its dark zini so I'll have to figure out what to brew with it. Always fun!

Hi all any clue on whether this is authentic zisha? From what i gather these pots
https://item.taobao.com/item.htm?spm=a1 ... 9728884699
are handmade by a relatively young potter costing about 120 usd, i first found this page when searching for the teapet that Mei Leaf has and found this potter who is supposedly friends with the person who made and sold the fish teapet to Mei Leaf. From what i gather from the shop, the teapots we see on the page are also out of stock they exist only for display and are made offline and often sold offline rather than online.

I think the obvious problem with this idea, besides decorations/handle/etc interfering, is the square cube law. It's likely that two pots with equally thin walls might be more like 100cc/100g and 150cc/120g.

Maybe better to just use calipers

I guess you could just use the Archimedes Principle to find out the volume and also the density of the object.

Bac the Julunzhu for sure is no older than 90s, none where made in Factory 1. Only antique or modern period.

Thanks bok, what about this strange sheen all around the hole on this presumed antique? Is it sign that is a fake pot? Or even worse chemical?
It cannot be cleaned of with a towel and cold water or hot water.

Which pot is that? Can’t tell you much by just the spout hole... looks like that spot is coming from a tool mark.

[Bok]

and the Si ting?

Is that the pot to the lid? That one is modern... in any case if it were supposedly old, your wallet would have noticed a couple of 1000s missing

What makes that modern? Too many black spots and too shiny?

[Bok]

Yep. This kind of clay is very obviously not old.

[Bac]

It is indeed under the lid of the Si ting, i think it is some kind of mixed clay, to resemble tian qing ni.
It was verified by some other expert, tho.... their guess might be good as mine, since they just look at the pictures and don't handle the pot in real life.
well, it wasn't so cheap
However the workmanship is not too bad,
Might decide to send it back or just keep it as tuition pot.
Will try to contact the seller and talk about this pot.
Couldn't be the shinyness just be patina? Or could it be mixed with shihuang maybe?
In effect with a wet test, this supposedly old pot does not wet as well as my other pots, water does not cling much to it, most of it just slides down.
However the inside of the pot looks pretty ok, it is not as shiny and water dries off pretty quickly if the pot is hot, and no chemical smells.
Still i have never seen the shininess under the lid, tool mark you say? Glue clay maybe?

[Bok]

@Bac tian Qing ni doesn’t look like that. Patina would be less even and a different kind of shine. Of you’ve seen real antiques it’s pretty obvious. The whole proportions as far as I can see and other details also don’t add up for an antique.

If this were to be real(for this kind of shape/quality) it would cost you at least 1000 or a lot more. If not it’s unlikely for the price paid alone. Anything less would be suspiciously cheap if the seller is aware it’s antique.

But I don’t even know what this clay is supposed to represent? For sure not imitating Zhuni, Zisha wouldn’t look like that either. This kind of shape would also not have badly processed clay with lots of spots, so... it’s a run of the mill pot, badly imitating old clay I’m afraid.

[Bok]

Not that I think it’ll change much, but do you have images of the inside?
