1* Yang Youlan (about 1711 - 1799) was a pottery artist during the Qing Dynasty. He specialized in yixing clay (zisha) teapots; and his works were often colourful in design. His teapots are valued at approximately 400- to 600- thousand yuan.
2* Yixing clay teapots, also called Purple Sand, are made from Yixing clay. This traditional style commonly used to brew tea originated in China, dating back to the 15th century, and are made from clay produced near Yixing in the eastern Chinese province of Jiangsu. Archaeological excavations reveal that as early as the Song dynasty (10th century) potters near Yixing were using local "zisha" (or "purple sand/clay") to make utensils that may have functioned as teapots. According to the Ming dynasty author Zhou Gaoqi, during the reign of the Zhengde Emperor, a monk from Jinsha Temple in Yixing handcrafted a fine quality teapot from local clay. Such teapots soon became popular with the scholarly class, and the fame of Yixing teapots began to spread. Yixing clay is composed of fine silt with an unusually high concentration of iron. These clays also contain mica, kaolinite and varying quantities of quartz. The percentage of clay, quartz, and iron in Zisha is optimally balanced to achieve low thermal conductivity and high permeability, as the texture of the clay has minute pores that trap the heat while permitting the exchange of air, which prevents the tea from becoming stale. Zisha (‘purple sand’) describes the reddish-brown color of the sedimentary soil which settled in ancient lakes and is now buried deep underground. The clay is compressed under heavy sedimentary rock formations throughout the Yixing region, southwest of Shanghai, in China’s Jiangsu province. Huanglong Mountain near Dingshu township has been the source of high quality purple clay ore for centuries. The mountain itself is rather ordinary – neither grand or pretty – but it is 350 million years old.
Yixing Zisha teapots are prized because their unglazed surfaces absorb traces of the beverage and develop a patina, which enhances the taste, color and aroma of fine tea. These teapots seem to be less functional at first glance, but they uniquely deserve the affection of tea connoisseurs. Flavors concentrate in the pot and are better controlled during brewing, then gradually revealed through different rounds.r that has been absorbed. Generally, the price of Yixing teapots are dependent on such factors such as age, clay, artist, style and production methods. For example, a pot was auctioned in 2010 for 12.32 million yuan.
