I dug out several interesting Nei Zi (inner Zi Sha) Wai Hong (outer Hong Ni) pieces and one very old and lovely “Er Pu”-sealed Shan Tou teapot 75cc. Let’s discuss the unique “Nei Zi Wai Hong” method to decorate yixing teapots and a Guangdong-system teapots: ShanTou Teapots.
The picture below shows (A) 80’s Nei Zi Wai Hong “Chung Guo Yi Xing”-sealed, (B) 70’s Nei Zi Wai Hong “Chung Guo Yi Xing”-sealed, and (C) the old Shan Tou teapot (the knob on the lid was broken, and repaired by plastic clay so not usable anymore but it’s a great learning material).

Nei Zi Wai Hong belongs to the group of decoration method for yixings: Make-up Clay, which mean a different type of clay, usually of finer quality of more interesting color, is applied onto the outer surface of the teapot’s body. Anoter example is the early R.O.C. “Pumpkin” of Jing-Ding Trademark. This decoration method has long existed in yixing production. But not until 70’s has it started been used in large scale for mass production of yixing teapots. The main purpose of using this method in the mass production was to eliminate the time and labor consuming burnishing work that can refine the surface texture. Another important reason is that it enables the use of lower grade clays as the Hong-Ni make-up clay on the surface would render them nice-looking red teapots anyway.
The picture below shows the inside clays. Note the difference in clay colors of A and B.

The clay of B, apparently paler in looking than A, is typical of 70’s zi sha that were used for making Nei Zi Wai Hong teapots. The color of A, more purplish, is closer to what we normally see in massively produced yixings nowadays.
Detailed look at the underside of the lids for A and B.

The arrow pointing to the knob’s hole of B highlights the “leaked” hong ni during the application step. Two ways to apply thick liquor of Hong Ni onto the surface: Paiting and Showering. If the thick liquor was showered onto the surface, very often some liquor would leak through the knob’s hole. So from the inspection of the underside of the lid, we can learn what method was used to apply the Hong Ni liquor.
Onto the interesting ShanTou teapots. Below is a picture of the ShanTou teapot I have, “Er Pu”-sealed.

ShanTou Teapots has a younger history than Yixing Teapots. In fact, they were made as “Yixing Wannabe” initially, as yixings were too expensive for daily use for general public of GuangDong province. So the potters used the local terra cotta-like red clay and hand-thrown on wheels to make the body. Because the color/texture of the local clays were not as attractive as the yixings, they used the “make-up(cosmetic) clay” skill to decorate those teapots.
To identify if a teapot is of the Yixing system or the ShanTou system, the first clue is to find if there are circular hand-thrown lines inside the teapot. If yes, it is most likely of ShanTou. If not, we then need to inspect the clay carefully. ShanTou clays are different from Yixing clays.
If the above discussion of YiXing vs. ShanTou is not complicated enough, several ShanTou teapot producers were so successful that later they went to YiXing to set up companies/studios to produce real yixing teapots. Among them, “Er Pu” is one of the most famous ShanTou teapot producers.
Although the Nei Zi Wai Hong yixings are usually of mass-produced kind, this producing method was soon out of fashion entering 90’s as modern clay-preparing skills and analytical chemistry dominate the production method. So for this reason, I still prefer a humble and genuine “nostalgic” yixing Nei Zi Wai Hong than those modern mass-produced kinds.
