“Looking” means carefully observing the porcelain up and down, inside and out. See if the glazed surface of the porcelain is smooth and smooth, with or without scratches, small holes, black spots and air bubbles. See if the shape is regular and there is no deformation. Check the screen for damage. Check whether the bottom is flat, and it must be placed stably without burrs.
“Listen” is to listen to the sound made when the porcelain is tapped lightly. If the sound is crisp and pleasant, it means that the porcelain body is fine and dense without cracks, and it will be completely porcelainized when fired at high temperature. If the voice is hoarse, it can be concluded that the porcelain body is cracked, or the porcelain is not complete. This kind of porcelain is easy to crack after being changed by cold and heat.
“Bi” is a comparison. For supporting porcelain, it is necessary to compare the accessories to see whether their shapes and screen decorations are consistent. Especially the complete set of blue-and-white or blue-and-white exquisite porcelain, because the color of blue-and-white porcelain changes with the firing temperature, so the same blue-and-white porcelain has dark and light colors. A set of several or even dozens of cold porcelain sets, such as each piece There are obvious differences in the color of blue and white, and this set of porcelain is greatly inferior. “Testing” is to test the cover, try to assemble, and test. Some porcelain has a cover, and some porcelain is composed of several components. When selecting porcelain, don’t forget to try the cover and assemble the components to see Whether it is suitable or not. In addition, some porcelain has special functions, such as Dripping Guanyin, which can drip water automatically; Jiulong Justice mug, when the wine is filled to a certain position, all the light will leak. So you have to test it to see if its function is normal.
Old and new respectively:
The so-called new bone china is essentially just a kind of white porcelain. By adding mineralizers and calcium oxide similar to bone powder to the porcelain body, the firing temperature, deformation, water absorption, and light transmittance of traditional porcelain can be improved. Affected by other aspects, a new material that is similar in appearance and quality to bone china is formed. Although it seems to have the whiteness and fineness of bone china, it is completely different from bone china in terms of essence and material.
Many merchants deliberately omit the word “new”. It seems that a set of bone china products can be done for only 1,000-2,000 yuan, but buyers have bought new bone china.
Not that new bone china is bad. It really all depends on personal preference. However, for those who want to buy bone china, there is a difference of one word, but it is a completely different thing.
The relationship between dinnerware and diet:
The advantage of plastic dinnerware is that it is light in weight and not fragile, but plastic dinnerware contains heavy metal substances harmful to the human body, which will affect human health after release; glass dinnerware is high in hardness and easy to clean, but crystal glass dinnerware is a high-risk source of lead pollution , and it is not suitable to be used to hold wine, because the lead in it will be dissolved out, which will affect human health.
Ceramic products are delicate and smooth and easy to clean. However, ordinary ceramics also contain some heavy metal substances. The brighter the color of ceramics, the more likely it will affect health; bone china dinnerware is the only recognized high-end dinnerware in the world at present. Bone meal is the main raw material, and it does not contain heavy metals such as money and cadmium. It is light and easy to clean.
