I though the goal here was to find a natural clay with good properties for tea pots... not replicate it in a lab.JBaymore wrote:Not the real Zisha... but maybe a starting point for some experimentation.

Why don't you simply contact a ceramic engineering firm in Taiwan and put them on the project?

A view radically different from mine. I know people who are full of spirit. They could get up, eat McDonalds, drink tea from mass produced cheap ceramic, and still tap into the spiritual mainline without any problems or hiccups.bagua7 wrote: Remove Yixing pottery from Taoist principles and you'll soon find out how good your Tai Chi Chuan or Bagua Quan is. An empty art with no spirit.

Actually that is NOT the goal of the original poster (luca):futurebird wrote:I though the goal here was to find a natural clay with good properties for tea pots... not replicate it in a lab.
People have already tried to do the later, the results are OK in some cases, but lack the depth and beauty of natural products.
His/her search has nothing to do with teapots.luca wrote:For my purposes, rather than tea, it's a product design venture for which the same properties that make Yixing purple clay ideal in the tea realm give it value in my intended application: the joint, often opposed properties of stoneware strength and earthenware porosity. In the world of ceramics, we do not find these two characteristics in the same natural clay body quite so effectively joined elsewhere, to my knowledge. (I am not a professional ceramacist, but have picked up a good deal of info in that area over the past few years of research).
They are very nice folks.futurebird wrote:I called them on the phone they were very nice. I wish we had a "clay center" like this one in NYC.
They said the clay is natural, foodsafe and from Yixing.
It can't be wheel thrown (or at least, not without additives). Generally, slab construction is used, but slipcasting is also possible.luca wrote: @ Futurebird and John, and anyone else who has worked with the clay, whether obtained from Chinese Clay Art or elsewhere, it's my understanding that it can be somewhat difficult – how exactly does it handle when working with it in the forms anyone here has had it? Can objects be formed via press techniques or only hand thrown?
