Yixing Zisha Clay Preparation Video
Watch how Yixing Zisha clay is prepared before a teapot takes shape. The video follows dry clay fragments through hand crushing, sieving and a traditional stone mill. These early steps are easy to overlook when you are admiring a finished pot.
What this Yixing Zisha clay preparation video shows
The clip is a close look at clay preparation, rather than a complete demonstration of teapot making. It shows the dry material being reduced to smaller pieces, checked with a sieve and worked through a hand-operated stone mill. It ends with a comparison between the coarse fragments and the material after its first pass through the mill.
The speaker describes this batch as Di Cao Qing clay from Huanglongshan, weathered for many years. The clay name and source are the workshop speaker’s description of this batch.

From weathered clay rock to smaller particles
1. Start with the weathered material
At the beginning of the demonstration, the clay looks more like broken rock than the soft, workable body used to build a pot. The speaker explains that these small fragments came from a much larger piece that had weathered over time.
For readers new to the terminology, our guide to Zisha, Yixing and Zi Ni explains how the place name, the broader clay tradition and individual clay names fit together.
2. Break down the larger pieces
Watch how the worker handles each fragment. He moves through the material, finds the larger pieces and breaks them into smaller fragments. He explains the immediate purpose plainly: smaller pieces are easier to grind.
The video does not specify a target particle size. It also does not show a single mesh specification that can be applied to every clay body. Keep the focus on what is visible here: reducing the large pieces before they enter the mill.
3. Sieve the fragments
A shallow metal sieve appears between the crushing and milling scenes. It gives a clear view of the different-sized fragments. This is a practical part of preparing a batch: the material is handled in stages rather than sent straight from a large lump of raw clay to a finished teapot.
4. Grind with a stone mill
The next sequence shows a traditional stone mill being turned by hand. As the upper stone moves, the clay is ground and collects around the lower part of the mill. The worker brushes the material together, then lifts some into his palm so the viewer can see its texture.
After one pass, the speaker says, this batch is still coarse. He expects at least another three or four passes. That number belongs to the material and method he is demonstrating; it is not a universal rule for all Yixing teapot clay.
What happens after the milling stage?
The clip stops before the dry material becomes a workable clay body. Adding water, further preparation and ageing belong to the broader process, but they are not demonstrated in this one-minute video. Nor does it show the pot being formed, dried or fired.
For a useful research reference, a 2025 study of Zisha clay recipes describes field observations of grinding, sieving and washing in traditional clay preparation. It also connects clay processing with changes in particle size and texture. Workshop methods and clay recipes vary, so a short demonstration should be read in that wider context.
Why clay preparation matters when choosing a Yixing teapot
A handmade Yixing teapot is the result of several stages of work. Clay preparation comes before construction, and construction comes before drying and firing. This video helps you see one part of that sequence at close range.
It is also a useful reminder to ask specific questions. What clay does the maker say was used? What documentation supports its source? How was the teapot made? Those questions connect the craft you see here with the pot you are considering buying.

English transcript
The following is the English translation of the spoken content in the video.
Take this batch. This is Di Cao Qing clay from Huanglongshan. It has weathered for many years, breaking into these small fragments. It was originally a very large piece of rock.
We break it down a little further. That makes it easier to grind. Every step follows traditional clay preparation methods. This stage is especially important. This piece is too large. Break it down.
After one pass, it is still coarse. It needs at least another three or four passes.
Common questions
Does this video show the full handmade Yixing teapot process?
It shows the preparation of dry clay material, especially crushing, sieving and stone grinding. Teapot construction and firing are separate stages.
What does Di Cao Qing mean in this video?
Di Cao Qing is the clay name used by the speaker for this batch. He associates it with Huanglongshan. We keep the clay name in pinyin in the English translation, rather than giving it a misleading word-for-word translation.
Does every batch need another three or four grinding passes?
The speaker gives that estimate for the material shown after its first pass. The video does not establish the same requirement for every clay or every workshop.
Can a video prove that a Yixing teapot is authentic?
A video can show materials and techniques. On its own, it cannot confirm that a particular finished teapot was made from that batch, identify its full provenance or replace supporting information from the maker.
