How to tell if an yixing teapot is slipcast?

[brandon]

It is actually easier to find slip-casting used in cheap Kyusu than Yixing.

This old favorite is a pretty good sample - "impeccably smooth."

So, is there any Yixing made with slipcasting like the links?

[Herb_Master]

There are certainly slipcast pots sold that purport to be yixing!

IS like this ?This is not the yixing zisha teapot.This is the chao zhou teapot.I don't know what opinion you are. Our government has forbidden chao zhou pot called yixing zi sha teapot .Yixing zisha teapot has already declared world non-material cultural heritage.Yi xing zisha teapot is not like this.

The video shows wheel thrown pots being made, this is a completely different process from slipcasting.

I believe yixing zi sha clay is considered unsuitable for wheel throwing which is why yixing pots are not made this way. But wheel throwing is a form of hand made teapot...Anyway wheel thrown pots are not the subject of the thread.

Wheel thowing isn't considered the a form of hand made teapot in china.It's cheap ,because it has a quicking product way.

Most of the wheel thrown chao zhou teapots I have seen for sale are anything but cheap.

Also wheel throwing compared to what we call slab handbuilding (the technique used for hand made yixing teapots) ...I´ve done both and wheel throwing is more difficult to learn and not especially fast compared to slab building. Actually the slab technique is taught much before the wheel in pottery classes because it´s easier for beginners to grasp the basics of.

In any case wheel throwing cannot be compared to slipcasting...like John said slipcasting can be learned in a couple of weeks and so can be performed by a technician.

How long it takes to teach someone to produce wheel thrown teapots to a high level of quality? I can´t do it and I studied pottery for a year...with not to brag but to make a point top marks...I can only make more simple forms consistently on a wheel. But I´d feel fairly confident handbuilding a teapot off the wheel.

Not to trash handbuilding off the wheel, many very beautiful teapots are made this way by skilled artists...but I think considering wheel throwing to be on the same level as slipcasting is unjustified since wheel throwing is a skill that takes many years of practice to really master.

This is an example of cultural value and maybe prejudice against other regional styles. It's like saying only Chinese teas are real teas. Different realities determined by cultural identity.

A new question has arisen for me regarding slip cast Chinese teapots. Is it possible to have "real" Yixing clay in liquid slip form, or are all slip cast Yixing pots in fact "mud clay?" What is mud clay in the Yixing pottery world- real zisha that has been watered down, or just some other clay taken from riverbanks and such?

It's possible to turn any clay into a liquid slip using very minute amounts (a few drops per gallon of slip) of deflocculant. Common deflocculants include long chain polymers that burn out of the clay, or a silicate of sodium that stays in the clay matrix by acting also as a mild "melter" (much like a feldspar). Using deflocculants keeps the clay dense by using less water to achieve the consistency needed for casting. Using a pressure mold casting system is a more industrial method which keeps the clay even denser than traditional pour casting.

Most clay dug up from the side of a riverbank is not good for making pottery at high temperatures, such as yixing. There are some exceptions to this, but it's very rare to find veins of clay in the ground that are good enough to make pots by themselves at higher temperatures. Many if not most of such riverbank clays would melt into glass in the kiln, assuming they would even hold their shape and dry without cracking.

Thanks for the info BBB! So in your estimation, slip cast Yixing pots are generally made from real zisha, but (generally speaking) perhaps not very good quality zisha by comparison to hand made or mold made pots?
