Select Yixing Zisha tea sets need to understand more raw materials

Yixing's Zisha tea sets can make tea not only really tea-scented, but also have no cooked soup and can maintain the color and aroma of tea for a long time. Su Dongpo is said to have designed a teapot. It uses the ancient blue branches that take the natural law as the handles of the pots, together with the enamel-shaped pots, engraved with ancient Vatian lines and exquisite calligraphy, elegant and unadorned, and contrasting colors to complement each other. It has been regarded as a practical treasure by ancient scholars. The common teapot used by ordinary people is made of moulds and has a coarse shale, but it still has the characteristics of its teapot "tea does not taste". There was a legend that when a plasterer repaired a house, he placed an Yixing Zisha pottery teapot on the ceiling of the roof and forgot to take it away after completion. After a few years, he discovered it when the house was repaired again. The color of soup, aroma, and taste haven't changed in the slightest. This legend may be somewhat exaggerated, but it also illustrates the performance and advantages of the Zisha teapot. Zisha tea sets have unique craftsmanship. They are both exquisite works of art and have special use values. They have always been praised. The literati praised Yixing Purple Sand, and the Song, Yuan, Ming and Qing dynasties had monographs for detailed introduction. Therefore, it is not a single sentence or two that can be explained clearly in the selection of purple sand tea, and the best thing is to present the tea set intuitively.

The world’s teaware teapot is the main source, so the selection of teapots should begin with the selection of teapot ingredients. It is known to all that mud, clay pot mud is divided into three kinds: purple clay, green mud and red mud. The mud that can be burnt in the teapot is generally deep under the rock layer and distributed between the clay mud layers. The thickness of the mud layer varies from tens of centimeters to one meter. It is fired under high oxygen and high temperature conditions, and the firing temperature is generally between 1100-1200°C. The water absorption rate of the finished teapot is greater than 2%. Zisha pot of mud raw materials for the three kinds of purple clay, green mud and red mud, commonly known as "Fugui". Because it is produced in Jiangsu Yixing, it is called Yixing purple sand. The original purple sand and mud is buried deep under the rock layer and distributed between the clay mud layers. The thickness of the mineral layer is from tens of centimeters to one meter, and its chemical composition is iron-containing clay siltstone. The main mineral composition of purple mud is hydromica, and not the same amount of kaolinite, quartz, mica and iron.

Mud production process: Purple mud mined from the seam, commonly known as raw mud. Massive rocks, weathered in the open air, make them loose, then they are crushed, crushed, and filtered according to the number of particles required by the product. After the screening, the ash is stirred by a mixer to form a piece of slush, which is put into a pile and aged, and then the sludge is vacuum-practiced, so that it becomes the used mud for the blank. In the process of purple sand mud training and preparation, the quality of water used is very particular. The quality of water will directly affect the quality of the product. Purple clay has good plasticity, high green strength, and the drying and firing shrinkage of the billet is small. Ceramic technologists mix several types of mud with different proportions, sometimes in mud and with coarse silt or steel sand, which are more eye-catching. The teapot is not necessarily a purple one. It presents a variety of wonderful colors after high-temperature firing. There are cinnabar red, maroon, red copper, jellyfish red, iron gray lead, sunflower yellow, dark green, blue green and so on. The teapot is not on *.
