What is the difference between pottery and porcelain, which is not the same object?

The difference between pottery and porcelain is mainly manifested in five aspects:1.The temperature at which it is fired is different; 2.

The glaze is different.

In our daily life, we often think of ceramics as a word, but in fact, ceramics are not the same object, and there is a big difference between the two.

In simple terms,Objects made from clay are called pottery, while objects made from porcelain clay are called porcelain. The word ceramics is a general term for pottery and porcelain, as long as it is made of clay and porcelain clay, which are made of raw materials, and are fired through batching, molding, drying, roasting and other processes, they are called ceramics.

However, although the firing process of the two is similar, there are also great differences.

The firing temperature is different in the firing process, the temperature requirements of porcelain are higher than that of pottery, the firing temperature of porcelain is generally above 1200, and even sometimes reaches 1400, and the firing temperature of pottery is sometimes below 800, and the highest is about 1100.

The degree of solidity is different, because the firing temperature of the pottery is low, so the body is not completely burned through, so the sound of hitting the pottery by hand will be relatively muffledPottery is less hard, so scratches can be made with sharp toolsDue to the high temperature of the firing, the porcelain body is basically completely sintered, when striking. will make a crisp and clear sound, andThe surface of porcelain is difficult to scratch.

It is fired using different raw materialsPottery can be made from ordinary clay, while firing porcelain requires a specific type of clay, known as kaolin

The surface of pottery is very different from that of porcelainPottery, no matter how thin or thick the body is, does not have the luster and transparency of the surface of porcelain, while no matter how thin or thick porcelain is, the surface will show a translucent luster

The glaze is differentPottery is divided into two kinds in the firing process: non-glazed and glazedIn the case of glazed pottery, the glaze melts when the firing temperature is low. There are also two kinds of glazes for porcelain, one is fired at a time with the body at a high temperature, and the other is to fire the blank at a high temperature, and then hang a low-temperature glaze, after a second low-temperature firing.

The main difference between pottery and porcelain is that the raw materials used in the production are not the same, the general clay can be used to make pottery, and the porcelain has higher requirements for materials, usually kaolin is used to make billets, and there are different requirements for temperature when they are made, the temperature of porcelain is better, and their appearance is different after being made, and the porcelain is harder and has translucent properties.

Differences: First of all, the raw materials for making tires are different, porcelain is made of porcelain clay, and pottery is made of clay. The second is that the firing temperature is different.

Porcelain requires more than 1200 degrees Celsius, and pottery generally costs 700 to 800 degrees Celsius. In addition, porcelain has no water absorption, and pottery generally has strong water absorption. Finally, porcelain has translucency, while pottery does not.

One: The raw materials of pottery and porcelain are different, pottery is fired using general clay, and porcelain is fired with kaolin. Two:

The temperature at which it is fired is different: Porcelain is fired at a much higher temperature than pottery. Three:

Porcelain is generally glazed or painted on the outside. Four: porcelain is harder and more durable than pottery.

Five: the pottery has a sense of simplicity, and the porcelain has a sense of exquisiteness.

Not really.

Pottery and porcelain are not the same thing, pottery is made of clay as a tire, processed and dried by hand kneading, wheel making, molding and other methods, and then placed in the kiln to fire the goods; Porcelain, on the other hand, is composed of porcelain stone, kaolin, etc., which is mixed, shaped, and calcined into an object with glazed or painted appearance.

Pottery is usually made from general clay billet, while porcelain needs to be made of specific materials, and porcelain is mainly made of kaolin. The iron content of pottery and porcelain is also different, the iron content of pottery tires is generally more than 3%, while the iron content of porcelain tires is generally less than 3%.

The difference between pottery and porcelain

1. The firing temperature is different.

Due to the different raw materials they use, there are also some differences in firing temperature. For example, pottery needs to be fired at a temperature of about 800-1000 degrees, while porcelain needs to be fired at a temperature of 1300-1400 degrees before it can be formed. On the basis of the temperature of pottery, add fire and heat, and the pottery becomes porcelain.

It can be said that porcelain is an upgraded version of pottery, and pottery is also the brother of porcelain.

2. The degree of hardness is different.

Since pottery is fired at a lower temperature, it has a lower carcass hardness and is slightly less durable. And its tire is coarse, the section has a high water absorption rate, and we will make a buzzing sound when we knock on it. The firing temperature of porcelain is higher, and the carcass has been basically sintered, so the fetal quality of porcelain is firm and dense, and the section will basically not absorb water, and the sound of porcelain is also crisp when we knock it.

The durability of the porcelain destroyer is good, the hardness is high, and its surface is not easy to be damaged by abrasion.

Hello! We are happy to answer your questions about pottery and porcelain. In fact, pottery and porcelain are not the same material. They all belong to the early ceramic products of Yuying, but there are obvious differences in the production process, texture, and performance of seepage punching.

Pottery is a relatively primitive ceramic product, usually made of clay as raw material and made by firing.

Porcelain, on the other hand, is a more delicate and high-grade ceramic product, which is made of porcelain clay as a raw material and fired at high temperatures. The texture of porcelain is more delicate and the performance is more superior, so it is widely used in high-end tableware, artwork and other fields.

Pottery and porcelain are different materials, although they share some similarities in the craftsmanship and appearance of making Pisza.

Pottery is an ancient pottery process that uses clay to be molded, purified and dried and fired at high temperatures. Because pottery is not sintered at high temperatures, it is usually coarse and does not have the hardness and resistance to high temperatures of porcelain. Pottery can be fired at low temperatures, with the general firing temperature between 800°C and 1050°C.

Porcelain is a kind of ceramic products made of high-temperature burning eggplant, and its raw materials are mainly porcelain clay, which is formed, dried and sintered at high temperature. Because porcelain is fired at high temperatures, its internal structure is denser, the surface is smooth, and it has high hardness and heat resistance. Porcelain is usually fired at temperatures above 1200°C, or even higher.

Therefore, although pottery and porcelain are both made of clay, they are not the same material because of their different manufacturing processes and properties.

Summary. Hello dear<>

The difference between pottery and porcelain is not that there is glaze or not, pottery can have glaze, such as Han Dynasty glazed glaze (commonly known as: Han green glaze), Tang Dynasty five-color glazed ware (commonly known as: Tang Sancai) and so on.

Porcelain can also be unglazed, such as white porcelain plain fetal ware, because the texture is white and delicate, so no one will see it as pottery. In fact, from the Shang and Zhou dynasties to the Warring States Period, the so-called hard pottery produced by porcelain stone in southern China has reached the degree of porcelain, and the sound of percussion is crisp and pleasant, which should also belong to the category of primitive porcelain.

The difference between pottery and porcelain is not anything.

The difference between pottery and porcelain is that one uses materials; Second, the temperature of firing, the two are indispensable. Pottery can be made of various mineral clays including porcelain clay, the firing temperature is low, mostly between 700 and 1000, the carcass is basically sintered, and it is no longer decomposed in water, but the porosity and water absorption rate are high. When observing the carcass under the microscope, there are very few glass-phase mullite crystals, in other words, there is no porcelainization, and the sound of percussion is dull.

The porcelain uses porcelain clay with a high alumina content, that is, aged clay firing.

The most basic tools of potters were their hands, but the long evolution of the history of pottery has led to the development of other additional tools, including potter's wheels and turntables, shaping tools (clappers, stepping stones, plasters), drum tools (wheels, clay machines, rollers), cutting tools (knives, grooving tools, wiring) and dressing tools (polishing stones, wooden sedan chairs, suede scales).

Ceramics and porcelain, due to their co-solvent number to alleviate the difference in metal composition, the difference in density of potato silver molds. Pottery has a muffled sound when impacted, while ceramics make a metallic sound, and the surface of ceramics is smoother than that of pottery, and it absorbs different amounts of water.

Dear, the above is for you to expand the content, thank you for the consultation, I wish you a happy life <>

Pottery and porcelain, the difference is that clay and porcelain clay are different; The sintering temperature is also different, and the firing temperature of pottery is lower than that of porcelain. Limb Annihilation.

This is like porcelain.

This is faience.

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 burned only the potato is not knotted, the sound is crisp when striking, and it is difficult to draw grooves with a general steel knife on the dry surface of the carcass.

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 has thin fingers like eggshells, 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.

Sixth, the concept is different.

Pottery: An item made of clay as a tire, processed and dried by hand kneading, wheel making, molding, etc., and then fired in a kiln. Porcelain China:

Porcelain is a kind of porcelain stone, kaolin, etc., which is mixed, formed, and calcined into an object with glaze or color on the surface.

<>1. The key suspicion of the material is different: pottery is made of ordinary clay as raw materials, while cavity porcelain is made of porcelain clay and kaolin; 2. The production temperature is different: the temperature of pottery firing is generally about 900, while the firing temperature of porcelain is 1300; 3. Different iron content:

The iron content of pottery is generally above 3, while the iron content of porcelain is generally below 3; 4. Different textures: the texture of pottery is relatively loose and porous; And the texture of porcelain is smooth and delicate.

Pottery is a tool made of clay or clay that is kneaded into shape and then fired into a hand-shaking hand. Pottery has a long history, and simple and crude pottery has been seen since the Neolithic Age. Pottery was used as a daily necessities in ancient times, and is generally collected as a handicraft now.

The invention of pottery is the earliest human use of chemical changes to change the nature of the beginning, is one of the signs of the development of human society from the Paleolithic to the Neolithic.

Porcelain is an important creation of the ancient working people. The forming of porcelain is to be fired at high temperature in the kiln, and the glaze color on the surface of the porcelain will undergo various chemical changes due to the different temperatures, which is a treasure displayed by Chinese civilization.

What we usually call "ceramic" is actually two different materials. Some friends may simply think that pottery is the kind of rough that has no glaze on the surface; Porcelain is porcelain with a smooth glass-like glaze on the surface.

In fact, such an understanding is one-sided.

In layman's terms: the utensils fired with clay are called pottery, the utensils fired with porcelain clay are called porcelain, and ceramics are the general term for pottery, stoneware (this will be introduced separately later) and porcelain. All utensils made of clay with two different properties of clay and china clay as raw materials, through batching, molding, drying, roasting and other processes can be called ceramics.

How do you distinguish pottery from porcelain? Below, I will introduce you to a few simple and practical methods.

1) Look at the tire color.

Regardless of whether the ceramic is glazed or not, there will be a part of the exposed "tire" at the bottom that is not glazed, such as the bowls and cups we use every day, and there is a ring foot at the bottom, which is relatively astringent to the touch, which is the fetus of the porcelain itself. If this part is red, brown, or darker gray, and opaque, it is almost certain that it is pottery, because the clay contains relatively high iron; On the contrary, if the tire color is white, transparent or translucent, it can be basically determined to be porcelain.

2) Listen to the sound.

Pick up the pottery and tap it lightly with your fingers, if the sound is crisp, it is porcelain, and if the sound is dull, it is pottery. Due to the relationship between materials, the firing temperature of pottery is generally 700 1000, and the firing temperature of porcelain is generally above 1200, and because the particles of clay itself are coarse, the sintering degree is not enough, and the molecules are not as close as porcelain clay, which is also the reason for the difference in their sounds.

3) Water absorption.

If you have drunk tea in a purple clay pot, you will understand that his water absorption rate is relatively high, the air permeability is good, and the moisture on the surface is easily absorbed by the surface, because the carcass pores are relatively large compared to porcelain. Porcelain, on the other hand, does not have such a high water absorption. The water absorption rate of ordinary pottery is above 8, and that of porcelain is 0 0 5.

It is important to note that the presence or absence of glaze is not an absolute way to distinguish between pottery and porcelain. For example, we can often see Tang Sancai, which is a kind of low-temperature glaze "pottery".

The above is only a relatively simple way to distinguish pottery and porcelain, and it is not completely accurate, and it is only by comprehensive consideration that it can be correctly distinguished. Comparing only one or two of these points is easy to misunderstand. For example, the black porcelain produced in Shangyu, Zhejiang, China, because of its iron content of 2 3, so the tire is also red, gray and other colors; The porcelain produced by the official kiln of the Southern Song Dynasty shows the color of the fetus, and it is used to"Purple iron feet"for precious; Because of its high alumina content in the tire, most of the northern porcelain cannot achieve dense sintering, and the water absorption rate is high, and some can reach more than 5.

These porcelains cannot be called porcelain if they are measured only against one of the above two items.

Therefore, in the actual identification, it is necessary to take into account the three aspects of raw materials, glaze and high temperature at the same time, the first two are internal factors, and the latter are external factors.
