How to distinguish pottery from porcelain, how to distinguish pottery from porcelain

Pottery and porcelain are essentially two different kinds of ware. Pottery was invented first, and porcelain was in pottery itself.

Developed on the basis of perfection, from the selection of raw materials, washing and refining, processing mud, drawing embryo molding, to.

and kiln roasting and other extensive processes are basically the same, the relationship between the two seems to be close, but from the formation.

The conditions and the composition of the internal components are very different, and they differ in the following ways:

1 The raw materials of the fetal soil are different.

Clay is a clay that is easy to obtain from nature to obtain the Denan diagram as raw material, porcelain clay is a kind of rock-like ore as raw material, after sintering in the kiln, from the fetal quality, the pottery is coarse, the porcelain is firm, the pottery is near the soil, and the porcelain is near the stone.

2 Differences in glazing.

The surface of the pottery is generally not glazed, or the low-temperature glaze with metallic lead as the flux, and the performance: strong water absorption and strong air permeability. Poor surface hardness and use strength.

The porcelain is full glaze, and calcium is applied as a high-temperature glaze to help melt. The properties are surface densification, strength and hardness are greatly improved. The glass texture is strong, breathable, and the water absorption rate is less than 1% or does not absorb water after physical testing.

3 The sintering temperature is different.

The sintering temperature of pottery is generally 700-800 degrees, and the process is simple.

The sintering temperature of porcelain is generally 1200-1400 degrees, and the process is complex.

The main differences between pottery and porcelain are as follows:

First, the firing temperature is different.

The firing temperature of pottery is generally lower than that of porcelain, and the lowest even reaches below 800 and the highest can reach about 1100. The firing temperature of porcelain is relatively high, most of them are above 1200, and some even reach about 1400.

Second, the degree of hardness is different.

The firing temperature of the pottery is low, the body is not completely sintered, the sound is questioned when striking, the hardness of the carcass is poor, and some can even use a steel knife to cut out grooves. The firing temperature of porcelain is high, the carcass is basically sintered, the sound is crisp when striking, and it is difficult to draw grooves on the surface of the carcass with ordinary steel knives.

Third, the use of raw materials is different.

Pottery can be made from ordinary clay to make billets and fired, while porcelain needs to be made of specific materials and made from kaolin. The firing temperature is at the temperature stage required for pottery, and it can become pottery, for example, white pottery in ancient times was fired in this way. At the temperature at which the kaolin is fired is made, the body becomes porcelain.

However, when the clay used to make pottery is burned, it cannot become porcelain and will be melted into glass.

Fourth, transparency is different.

Even if the body of pottery is relatively thin, it is not translucent. For example, the black pottery of the Longshan culture is as thin as an eggshell, but it is not transparent. The carcass of porcelain, regardless of its thickness or thickness, is translucent.

Fifth, the glaze is different.

There are two types of pottery: unglazed and glazed, and the glaze of the glazed pottery can be melted at a lower firing temperature. There are two kinds of glazes for porcelain, which can be fired with the carcass at a high temperature, or hung with a low-temperature glaze on the high-temperature plain tire and fired at a low temperature for the second time.

Among the above aspects, the most important conditions are raw materials and firing temperature, and several other conditions are closely related to these two conditions. Therefore, once the potter mastered the technique of firing temperature and recognized the difference between kaolin and general clay, he was able to invent porcelain.

Pottery is relatively coarse.

The surface of the porcelain is smooth.

1. Listen to the sound: the percussion sound of porcelain is very crisp, and there will even be a metal sound, and the heat transfer is slow; The pottery is loose because of the loose fetus, there will be fine pores, and the percussion sound is far less crisp than the porcelain, and the sound is muffled.

2. Water absorption: The water absorption rate of pottery is much higher than that of porcelain. Storing liquor and other liquids in pottery will cause leakage, while porcelain has a high fetal density, and the surface is covered with a high-temperature glaze, which will hardly absorb or seep water.

3. Glazing: Most of the pottery will not be glazed. Both faience and painted pottery belong to the application of color rather than glazing. Later, although some pottery was glazed for special reasons, because the pottery firing temperature was low and easy to peel off, it was not until the Tang Dynasty that the firing of glazed pottery began to mature and flourish.

1. Listen to the sound: The percussion sound of Tanyan porcelain is very crisp, and there will even be a metallic sound, and the heat transfer is slow; Pottery will have fine pores because of the loose fetal quality, and the percussion sound is far less crisp than porcelain, and the sound is muffled.

2. Water absorption: The water absorption rate of pottery is also much higher than that of porcelain. Storing liquids such as wine in pottery can cause leakage, but porcelain's high fetal density and high-temperature glaze applied to the surface make it almost impossible to absorb or seep water.

3. Glazing: Most of the pottery will not be glazed. Painted pottery and painted pottery both belong to the application of color, and the spring hail is not glazed.

Later, although some pottery was glazed for special reasons, because the pottery was fired at a low temperature and was easy to peel off, it was not until the Tang Dynasty that the firing of glazed pottery began to make Senyu mature and prosperous.

Dear, hello, I'm happy to answer for you, I'm the exclusive ** teacher who accompanies you, thank you for your patience! The difference between porcelain and pottery mainly lies in the difference in raw soil and temperature. 1. The utensils fired with clay are called pottery, and the firing temperature is 900-1200 degrees Celsius, and the low ones are only six or seven, and the utensils fired with porcelain clay are called porcelain, and the firing temperature is 1300-1400 degrees Celsius.

Ceramics is a general term for pottery, stoneware, and porcelain. 2. The body of porcelain is completely sintered, with very small porosity, high mechanical strength, and high firing temperature; However, the sintering degree of the pottery body is poor, the porosity is large, and the firing temperature is also low.

Pro, porcelain and pottery can be divided from the following perspectives:1Ingredients:

Porcelain is a kind of porcelain material made of kaolin as the main raw material through a special production process; Pottery is a kind of ceramic material produced with clay as the main raw material. 2.Production process:

Porcelain is a hard material made of high temperature, high pressure and other processes, and its production process includes multiple steps such as molding, drying, and firing; The pottery is made of low-temperature and low-pressure strip spikes, and the production process includes several stages such as molding, drying, and firing. 3.Material features:

Porcelain is famous for its delicate texture, translucent, hard, resistant to acid and alkali corrosion, and easy to clean; Pottery is famous for its diverse colors, soft texture, and strong decoration. Not all products are pure porcelain or pottery, and some materials belong to a mixture of multiple materials between porcelain and trouser leaky pottery, so the division is flexible and diverse, and it also needs to be viewed in context.

1.The main component of pottery is clay, and the firing temperature is between 800 and 1000 degrees; The main component of porcelain is kaolin, the color is white, and the lowest firing temperature is 1200 degrees; 2.Tao's voice is muffled, the echo is short, and it is opaque; The sound of porcelain is crisp and loud, with a long echo and strong light transmittance.

The main differences between pottery and porcelain are:

l) Different raw materials for tires: pottery generally uses clay, a few also use porcelain clay, and porcelain is made of porcelain stone or porcelain clay, due to different raw materials, its composition is different. Taking Yixing purple sand pottery as an example, its mineral composition belongs to the iron-containing clay-quartz-matriarchal system, and the iron exists in the form of hematite, and the main phases are quartz, mullite and mica remains, and the crystallization is fine and uniform.

Kaolin fired white pottery is a type of clay with kaolinite as the main component, which is white or off-white in color and has a dull luster.

2) Tire color: The iron content in the raw materials of pottery tires is high, generally red, brown or gray, and opaque; The porcelain is white in color and transparent or translucent.

3) Firing temperature: Due to the relationship between the tire making materials, the firing temperature of pottery is generally 700 1000, and the firing temperature of porcelain is generally above 1200.

1. Pottery is made of clay, and porcelain is kaolin; 2. The firing temperature of pottery is between 800 and 1100, while that of porcelain is above 1200; 3. The texture of pottery is rough, the color is dull and opaque, while the texture of porcelain is smooth, the surface is usually translucent, the reflective ability is strong, and the color is bright; 4. The hardness of pottery is poor, while the hardness of porcelain is high.

The surface of the pottery is not smooth The surface of the porcelain is smooth.

It's easy to compare the bowl in your house with the tiles of the rural house!

The differences between pottery and porcelain are as follows:

1. Pottery with Pu.

Through clay, porcelain is kaolin. Pottery has a close relationship with porcelain, first of all, porcelain is only white, and pottery in addition to white also has red, brown, black, etc., but whether it is porcelain or pottery can be changed by adding colorants; 2. Secondly, the firing temperature of porcelain is high, above 1200, while pottery is only between 600 and 800;

3. The sintering degree of porcelain is strong, the carcass is hard and dense, and the relative texture of the pottery is relatively loose;

4. The porcelain percussion sound is crisp and loud. The sound of Tao percussion is hoarse;

5. The water absorption rate of porcelain is small, almost no water absorption, and the water absorption rate of pottery is high;

6. Porcelain has translucency, pottery is opaque, and the chemical properties and mechanical strength of pottery are not as good as porcelain.

(1) The tire material of pottery is ordinary clay, and the tire material of porcelain is porcelain clay, that is, kaolin (named because it was first found in Gaoling Village, Dongxiang, Jingdezhen, Jiangxi Province);

2) The iron content of ceramic tires is generally more than 3%, and the iron content of porcelain tires is generally less than 3%;

3) The firing diffuse of pottery is generally about 900, and porcelain needs a high temperature of 1300 to be fired;

4) Pottery is mostly not glazed or glazed at low temperature, while porcelain is glazed;

5) The pottery tire is coarse and sparse, and the water absorption rate of the section is high. The porcelain is roasted at high temperature, the tire is firm and dense, the section basically does not absorb water, and it will make a sonorous metal sound when struck.

This is porcelain This is pottery, the difference is obvious, the thickness of the particles, the heat, the permeability, the luster and so on are different.

What is the difference between pottery and porcelain?

The difference is in the water absorption. The water absorption rate is less than that of porcelain, more than 10% of which is pottery, and between the two is semi-porcelain.

Ceramics are made of natural clay and various natural minerals as the main raw materials through crushing, mixing, molding and calcination. All utensils made of clay with two different properties of clay and porcelain clay as raw materials, through batching, molding, drying, roasting and other processes can be called ceramics. Ceramics is a general term for pottery, stoneware, and porcelain.

1. The times are different.

As early as the Neolithic Age, pottery was invented in China; With the continuous improvement of pottery technology, the successful firing of white pottery in the Shang Dynasty laid the foundation for the emergence of primitive porcelain.

2. The raw materials are different.

The tire material of the pottery is ordinary clay; The tire material of porcelain is porcelain clay, i.e. kaolin.

The iron content of ceramic tires is generally more than 3%; The iron content of porcelain is generally less than 3%.

3. The firing temperature is different.

The firing temperature of pottery is generally around 900; Porcelain requires a high temperature of 1300 degrees Celsius to fire.

4. The degree of glazing is different.

Pottery is mostly not glazed or glazed at low temperatures; Porcelain is glazed.

5. The water absorption rate is different.

The pottery tire is coarse and sparse, and the water absorption rate of the section is high; The porcelain is roasted at high temperature, the tire is firm and dense, the section basically does not absorb water, and it will make a sonorous metal sound when struck.
