Attach the classification of purple mud and the tea suitable for brewing with purple mud.
Purple mud is divided into three types: purple mud, cinnabar mud and Benshan green mud, with purple mud as the main one. Three kinds of mud can be made into pottery separately, or mixed with each other to make different colors! The mud dug out of the mine looks like rock, which cannot be directly expanded by water, but can be weathered into fine particles after aging. The traditional processing method is to crush and sieve with a stone mill, add water to mix, and then manually turn over and hammer until the ideal plasticity is achieved and the finished mud is made! Now, it will be crushed with a ball-throwing Raymond crusher, sieved, stirred with water, and made into finished mud by a vacuum mud refining machine!
Yixing teapot enjoys a world-renowned reputation and has always been a favorite of collectors. Zhu mud, red mud, purple mud, cyan, satin and black iron ore are collectively called purple sand. Due to the good texture of purple sand, the water absorption and exhaust speed after firing are moderate, and it is good in color, fragrance and taste when used for making tea. Purple sand teapot has a good mutation of hot and cold when washing, and it is not easy to burst, so it is more suitable as a tea set than ordinary ceramics. The beauty of the teapot, in addition to its unique shape, also has its unique exposed texture lines and material color beauty.
Purple mud includes purple soil, red soil and mountain green soil (profile soil), which are collectively called "purple mud".
The color of purple, red and yellow seed-based mud is unpredictable, subtle and ingenious due to various factors such as different mining areas and seams, different processing techniques and baking temperature.
Sunburn: Expose the mined purple sand mine in the open air, let it be exposed to the wind and rain, because the newly mined purple sand mine is extremely hard and firm, so it must be exposed to the open air, and let it be naturally weathered and disintegrated by the sun, wind and rain. The longer the weathering time, the better.
Stale: the mined purple clay ore is dried, sieved, crushed, collected, sieved, stirred with water and bound in vacuum. After the purple sand mud ore is refined into mature mud, it needs to be kept at a certain temperature and humidity to prevent it from drying out. Wet mud becomes "sludge" after aging. Let the water distribute evenly, let the mud rot and the organic matter decompose to produce colloid. This method is "nourishing soil".
Benefits of soil culture: it can improve plasticity and reduce cracking during molding and drying in the shade. After firing, the epidermis crystal is moist, and after long-term use, it gradually becomes sharp, and the cultivation changes greatly.
Zhuni Stone Yellow Mud in Zhaozhuang Mountain is a tender mud raw material selected from Zhaozhuang Stone Yellow Mud Mine in Dingshan, Yixing City, which contains many special natural mineral components such as silica and timely.
Red mud red mud is the most commonly used mud in the early days, which is extracted from the original red mud mine in Huanglong Mountain, Yixing, Jiangsu Province. At that time, due to the high iron content in the vein, the teapot made would have fire defects and a small melting point. When the new pot was first used, the tea soup was slightly dusty, and the pot body was scarlet after use. Tea? ? Days are like vermicelli.

Kiln temperature: about1100 c/shrinkage: about 13%.
Suitable for brewing: Oolong raw tea (light baking fire series), Tieguanyin (medium baking fire or heavy baking fire series) and Pu 'er tea series.
Satin mud is an early rare mud, which is refined from the original green mud mines in Huanglong Mountain and Benshan Mountain in Yixing, Jiangsu Province. The porous structure with large particles in the mud is obviously double-hole structure, and the air convection is smooth; The temperature of early mud mixing and early kiln entry is low, and the general satin mud products will "spit black"; The kiln used recently is a high-temperature kiln, and the satin pottery pot can easily be raised to the required temperature, and it really achieves high crystallization with little black spitting.

Black iron ore Black iron ore is one of the most common and universal mud materials in the early stage. It is made by adding manganese to the raw ore of Huanglong Mountain in Yixing, Jiangsu Province. At that time, due to the high iron content in the vein, the teapot made would have fire defects and a small melting point. At the beginning of the new pot, the sand is heavy and the tea soup is slightly sand. After the pot body is used, it is grayish black. How to make tea? ? The days are as black as ink.

Lanshan Zhu Ni, also known as Little Red Mud, is a kind of tender mud mined in the eastern mining area of Fudong Town, Yixing City. Because it contains a lot of iron oxide, it will turn into cinnabar (also known as little red mud) after kiln burning. The fine density and high crystallinity of this mud are different from the mineral content of ordinary red mud.
