Who knows what kinds of clay are used to make purple clay pots? What are the colors of purple sand w

There are three main types of purple mud, purple mud, green mud and red mud. Collectively known as purple sand mud. Purple mud is a kind of mud produced in the clay mud mine, the green mud of this mountain is yellow after firing, and it is the grease in the mud mine; Red mud, also known as cinnabar mud, is a mud material sandwiched in clay tender mud mine.

Nail mud and tender mud are the raw materials used in Yixing daily pottery for a long time, and the purple sand mud is therefore called "mud in the mud".

In the mining of Yixing pottery raw materials, the proportion of purple sand mud is not much, about one thousandth. Purple sand mud belongs to the kaolin-quartz-mica type, which is characterized by high iron content and coarse particles. The three raw materials of purple mud, mountain mud and red mud can be used separately to make utensils, or they can be mixed with each other according to their needs.

The mined purple sand ore can not be directly expanded with water, but should be scattered in the open air, weathered and stale for a few months, and then crushed, sifted, and mixed with water. The processed and molded bad parts are no longer glazed, and they are fired by a flame of 110 to 1,000 degrees Celsius to obtain a finished product with elegant color and strong texture. The color of the product, mainly purple red, so called purple sand pottery, due to the different proportions of raw materials, can also get cinnabar purple, deep purple, maroon, pear peel, begonia red, azure, blue gray, dark green, black and other different colors.

Bottom groove green mud material. The mud is generally divided into three series, purple mud, red mud, and green mud. All mud is inseparable from these three main series of mud, clear cement belongs to the purple mud category, vermilion mud belongs to the red mud category, and the bottom tank Qinghe Duan mud is a symbiotic mine.

The bottom groove green mud is the best purple mud at present.

Benshan green mud: the ancient name is "pear peel mud". The mineral soil is pale green layer flake, and the pear skin is frozen (beige) after firing into pottery. It is produced in the symbiotic ore layer of Huanglongshan rock layer and purple mud, only a few centimeters thick, between the upper layer of purple mud and rock slab, commonly known as "dragon tendon".

The original ore of the section mud is currently very rare, and now the Yixing pot makers have begun to use the green mud and purple mud of the mountain to artificially mix to form an unnatural section of mud.

Purple mud, red mud (vermilion mud), group mud (section mud).

1.The mud of purple clay pots is mainly divided into three categories, namely purple mud, red mud and green mud.

2.Clay is one of the most important factors in determining the taste of purple clay pots, and almost all clay materials are inseparable from these three main clay materials.

3.Not only does each mud have its own characteristics, but also the type of tea that suits it is also different.

The types of purple clay pot mud are azure mud, bottom groove green mud, red brown mud, big red mud, Benshan green mud, 100 hemp seed mud, and red hemp seed mud.

1. Azure mud.

The mud is delicate and blue-blue. It was produced in the middle of the Qing Dynasty and is now lost. Guyun "azure color", blue light flashes in the dark liver color, named after the color of the ore, and is produced in the Dashuitan mine in the center of Dingshu Town.

2. Green mud in the bottom groove.

Located at the bottom of the ore layer, there are blue-green "corns" and "cat's eyes" in the block, the color is purplish and blue, fine and pure, very rare. It was first produced in Huanglongshan No. 4 well, and later Huanglongshan No. 5 well and Taixi mine.

3. Red brown mud.

Red brown mud is a layer of a mud ore layer, the ore body is thin, lens-shaped, the thickness of the ore layer is generally about tens of centimeters to one meter, the stability is poor, the appearance color of the raw material is purple, purple-red, and with light green spots, and the appearance color is purple, purple-brown, purple-black after firing.

4. Big red mud.

Located in the ore seam, it occurs in small quantities. The cloud-like structure is purple-red, bright and bright. The distribution of ore layers is different, and the firing temperature range is wide, and the optimal sintering temperature is about 1180.

5. Green mud in this mountain.

The amount of mining is very small, it is not easy to make large products, only for small products and "makeup soil", adding an appropriate amount of coloring agent can be changed into a color decorative mud.

6. Hundred hemp seed puree.

The color is similar to the green mud of this mountain, and the texture is coarse. It is located in the upper layer of purple mud, and there are many impurities, it must be carefully selected before it can be used, and it is light ink color after becoming pottery.

7. Red hemp seed puree.

The color is like purple mud and the texture is coarse. It is located in the upper layer of purple mud, and the green mud of pockmarks is sandwiched between the stars, and it is peach-colored after becoming pottery.

There are three types of purple clay pot mud: purple mud, green mud and red mud.

The mud that can be used to make purple clay pots is generally hidden deep under the rock layer, and the thickness of the mud layer varies from tens of centimeters to one meter.

According to the analysis of the lithofacies of the Shanghai Institute of Ceramics, the purple sand yellow mud belongs to the kaolin-quartz-mica type, with a high iron content, and the highest iron content is reached.

The purple clay pot is fired under the condition of high oxygen and high temperature, and the firing temperature is between 1100-1200.

The water absorption rate of the finished purple clay pot is greater than 2%. The mud raw materials of the purple clay pot are purple mud, green mud and red mud, commonly known as "rich soil". Because it is produced in Yixing, Jiangsu, it is called Yixing purple sand.

Purple sand mud can be roughly divided into three categories: purple mud, red mud and section mud. If you subdivide it, you can sprinkle it into many kinds.
