Seeing this title, I think everyone knows the topic we are going to share today~ Yes, it is the clay legend of the purple sand circle, Tianqing clay and black star sand. These two clays can be said to be the clays that many pot players dream of, and even many pot players have been pursuing these two clay teapots all their lives. So, what is the mystery of these two clays, and what kind of past and present? Let's look down~
There is a record in the ancient book "Yixing County Chronicles": "The soil is green and yellow, and it is used for tuan. Tianqing clay is expensive in all kinds of clay, and it is specially used by those who make tea pots, and yellow clay is used for cylinder urns." It shows the exquisiteness of Tianqing Clay!
Historically, Tianqing clay was produced in the Lishu mining area of Huanglong Mountain, which is the "big water pool" we often hear nowadays. Let's take a look at the mineral material of Tianqing Clay: it is produced under the green gray and purple clay, with reddish in the purple, dense lumps, uniform texture, fragile and slightly hard
Ming Dynasty Zhou Gaoqi’s "Yangxian Tea Pot Series" said: “Tianqing green clay comes out of Lishu, and Tao Zhi becomes dark liver color.” Therefore, after the Tianqing clay is fired, it generally has a dark liver color, but it will change with the temperature of the kiln. The color changes and the color changes. The picture below is Yang Fengnian’s "Wind Rolling Sunflowers" work, which is one of the more famous works of Tianqing clay, and is now housed in the Zisha Museum.
In fact, it is not difficult for us to find that you go to the Internet to collect Luo Tianqing clay, and the overwhelming "green" pots are displayed in front of you. Many people think that since it is called Tianqing clay, it must be blue or green, so the market's "green" "The pot was very popular at one time. But the sky green clay belongs to the purple mud category after all, and the color is in the dark liver. Do you think those green pots are still reliable?
I have met a lot of pot friends and opened their mouths and asked: Can I still buy a purple clay pot from Tianqing clay? The answer is definitely no! The Tianqing clay was lost as early as the end of the Qing Dynasty, and the Tianqing clay works that can be seen today can only be found in museums~
Black Star Sand is also called Black Star Soil, and it was also very popular in the purple sand market for a while. So is it raw ore clay or is it made of blending? In the early days, the black star soil material of the original ore did exist in the purple sand world. It has good viscosity and high iron content. After firing, the body of the pot will show many dense small black spots, which is also a significant feature of the black star soil.
However, the output of a single raw ore Black Star Soil was too small, so later the old artists of the No. 1 Zisha Factory assembled this material of Black Star Soil. They use natural manganese powder to mix the black star soil clay, so don't put the black star soil from the old factory into the category of chemical materials. After all, the addition of natural manganese powder has a history of ancient times. Most of the common black star soil purple clay pots on the market are mainly made of metal manganese oxide, so it is better not to touch them for newcomers.
These two purple clay clays are legendary materials in the purple sand world, and many people are particularly curious. But curiosity returns to curiosity. Let's first understand the past and present of these two clays, and then think about whether to use them! Okay, that’s all for today’s sharing, and we will continue to talk in the next issue~
