What is the difference and connection between pottery and porcelain?

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.

Although ceramics are called together, "pottery" and "porcelain" are very different.

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 application of ceramics in life is very extensive, including ceramic tiles in decoration materials, dishes in tableware, porcelain used in decoration and bathroom sanitary ware, etc., are ceramic products, in fact, ceramics in life is not a thing, it is divided into pottery and porcelain, is different materials, but often people will mix it up, although the use is similar, but there are still a lot of differences, so what is the difference between pottery and porcelain? Let's take a look with Qeeka Home experts.

1. What is the difference between pottery and porcelain?

The main difference between pottery and porcelain lies in the raw soil, production temperature, texture of these three aspects, porcelain products are generally made of kaolin materials, firing temperature of 1300-1400 degrees, so the texture is hard, fine, high temperature resistance, and ceramic products are made of clay, clay and other materials, the firing temperature is 800-1000 degrees, the texture is loose, there are obvious particles.

Second, what are the classifications of ceramics.

1. According to the use.

Ceramic products have different applications in life, mainly daily ceramics, craft ceramics, industrial ceramics these three uses, of which tableware, tea sets, plates, etc. belong to daily ceramics, vases, sculptures, utensils, photo frames, etc. belong to craft ceramics, and industrial ceramics are also more applications, bricks, face bricks, exterior wall bricks, etc. belong to architectural ceramics, sanitary ware is sanitary ceramics, high alumina oxygen porcelain, magnesia porcelain, titanium magnesium porcelain, etc. belong to special ceramics.

2. According to the material.

From the point of view of materials, it is divided into two kinds of pottery and porcelain, including stoneware, fine pottery, stoneware, semi-porcelain, porcelain, etc., which are divided according to the thickness and fineness of the raw materials, stoneware is the most primitive pottery, made of fusible clay, the porosity is too high when made, frost resistance, high temperature resistance is not good, and porcelain is a higher stage of the development of ceramics, completely sintered products, is very dense, basically will not permeate gas and liquid.

Summary: The above is an introduction to the difference between pottery and porcelain, I hope the content shared can give you some reference, if you want to know more about relevant knowledge, you can **** Qijia to consult.

1. What is ceramic? What is the difference between pottery and porcelain?

1. Ceramics are hard substances formed by clay raw materials (such as black mud, mainly imitation kaolin) and barren raw materials (including aggregates such as high-temperature sand quartz and flux raw materials such as low-temperature sand feldspar) through appropriate batching, crushing, molding and a series of physical and chemical reactions under high-temperature roasting.

2. The difference between pottery and porcelain is the water absorption. The water absorption rate is less than porcelain, more than 10% is pottery, and between the two is porcelain, which is also called stoneware.

3. Water absorption rate refers to the percentage of the quality of water adsorbed by the pores of ceramic products to the quality of the product.
