Tea Wall

At the beginning of the Ming Dynasty (1368-1644) in China, leaf infusion as we know it now became popular. The earliest examples of teapots come from this period, made from the zisha, or "purple" clay, of the YiXing region of China. Pottery in the YiXing tradition has been strong since the Sung Dynasty (960-1279); wares are valued for their fine texture, thin walls, and naturally beautiful coloration ranging from light buff to deep maroon tones. The transition from drinking bowls to teapots was a smooth one. YiXing teapots were, and still are, used to brew tea as well as act as the drinking vessel -- one sips directly from the spout of a single-serving pot. YiXing teapots gradually season, the unglazed clay absorbing the flavor of brewed tea, making them a favorite choice for tea lovers. The dissemination of YiXing teapots greatly influenced not only the forms of teapots found throughout the world, but also prompted the invention of hard-paste porcelain in the western world.
According to Chou Kao-ch'i, author of Yang-Hsien ming hu hsi, an account of Yixing(pronounced yeeshing) teapots, early in the sixteenth century, the potters at Ihing, a few miles up to Yangtze from Shanghai, became famous for teapots known to Europeans by the Portuguese name boccarro (large mouth). These were small, individual pots. which came to Europe with teas and served as models for the first European teapots.
