We know that porcelain is indispensable for glazing and firing. Porcelain blanks can only be called porcelain if they are porcelainized after glazing and firing. The opposite is of course pottery. The difference between pottery and porcelain is not only the raw materials but also matter with the firing temperature. The materials for making pottery are different from those for porcelain. For example, the main raw material of pottery is clay, and the firing temperature is also different. They are two things. . Porcelain can be divided into high-temperature porcelain, medium-temperature porcelain, and low-temperature porcelain due to the difference in glazing firing temperature. Of course, it can also be divided into three types: over-glaze color, under-glaze color, and in-glaze color according to different flower decorations.
High-temperature porcelain refers to porcelain that is fired at a high temperature above 1200°C after the porcelain body is glazed. Only at this temperature can the glaze applied on the porcelain body be fully porcelainized. The porcelain of all-ceramic porcelain is very fine, and relatively hard, and the porcelain surface has high strength and is not easy to scratch, and the sound is very crisp. The non-matte high-temperature porcelain surface has a strong sense of glass and is pure white and the water absorption is very low when cleaning. There are also many kinds of glazes used on porcelain. Not all glazes are the same for porcelain. For example, the glaze used for high-temperature porcelain is different from the one used for low-temperature porcelain.
Low-temperature porcelain refers to porcelain that is fired at a temperature between 600°C and 900°C after the porcelain body is glazed. Because the temperature is not as high as that of high-temperature porcelain, the glaze layer on the surface of the porcelain body cannot be completely porcelainized. The porcelain is not very fine and hard, and its hardness is not as high as that of high-temperature porcelain. The strength of the porcelain surface is relatively low, so it is also very easy to scratch. damaged. Over time, the glaze may crack or the porcelain may leak.
1. High-temperature porcelain can be fired at high temperatures again, but low-temperature porcelain cannot.
2. The water absorption rate of high-temperature porcelain is lower, less than 0.2%, and it is not easy to absorb odor. Low-temperature porcelain has a high water absorption rate and is not easy to clean.
3. Because of the complete porcelain, the sound is crisp. The sound of low-temperature porcelain is relatively dull.
4. Harder than low-temperature porcelain, the porcelain surface has high strength and is not easy to scratch.
5. The color of high-temperature porcelain is whiter, smooth, and delicate, while the color of low-temperature porcelain will be yellowish and rough.
In fact, bone china is also a kind of low-temperature porcelain, but the water absorption rate of bone china is less than 0.003%, so it is very convenient to clean. Generally, oil stains only need to be cleaned with warm water. In terms of color, because of the addition of natural bone meal, it is milky white, and there is some yellow and milky white that is unique to the bone meal in the white. There is a special sense of cleanliness visually, and dining is also very ceremonial. The heat preservation performance is a point pursued by many hot drink lovers, and it retains the mellow taste of coffee or black tea.
The biggest difference between high-temperature porcelain and low-temperature porcelain is the water absorption rate. If it is not easy to distinguish on the surface, it can be identified by the water absorption rate. The formula for calculating water absorption is the weight of porcelain after the experimental test – the original weight of porcelain/original weight of porcelain. The original weight of porcelain is the weight obtained by directly weighing the porcelain itself. The experimental test has the weight of porcelain, that is, there are three ways to test the water absorption of porcelain. First, put the porcelain in cold water and boil it for 2 hours, then take it out and measure the weight, which is the weight of the porcelain after the experimental test. The second is to soak the porcelain in clear water for 24 hours, then take it out and weigh it, which is the weight of the porcelain after the experimental test. The third is the vacuum immersion test with professional instruments, which is the weight of the porcelain after the experimental test.
