Due to the addition of ashes, the hardness, transparency and strength of bone China are higher than that of ordinary China and twice that of daily-use China. Because of the unique formula, the bovine bone powder is added, which eliminates the impurities in the porcelain mud. Bone porcelain is whiter, more delicate, more transparent, lighter, less defective and thinner than ordinary porcelain, and has a special sense of cleanliness visually. The higher the dosage of bone meal, the lower the composition of clay, and the easier it is to burn and crack in the production process, which requires higher technology in molding, increases the difficulty of firing, and the yield is lower, so it is more precious.
The color of bone China is a natural milky white unique to natural bone powder. Generally speaking, porcelain containing 25% bone powder in raw materials can be called bone porcelain, but it is recognized that the best bone porcelain in the world generally contains 45% high-quality bovine bone powder. Among them, bone powder accounts for more than 40%, and the color of the appliance is milky white, which belongs to high-grade bone porcelain.
Question 2: Is there bone powder in bone China? High-quality bone China is made of feldspar and stone clay as the main raw materials, and a large number of bovine ashes with less impurities are added to the raw materials.
Bone China is the abbreviation of bone China, and its scientific name is bone China. It is a kind of porcelain made of animal bone charcoal, clay, feldspar and timely, which is fired twice by high-temperature plain firing and low-temperature glaze firing. According to the standard of bone China made in Britain, it contains 30% tricalcium phosphate from animal bones, and the finished product is translucent, so it is called bone China.
Question 3: What is bone China? What kind of bone China is good? The so-called bone China was invented by the British in 1794. It is named after adding the ashes of herbivores such as cattle and sheep (preferably bovine bone powder) to its clay, and it is an environmentally friendly green consumer product.
The formation of bone China mainly depends on silica, alumina and calcium oxide. The higher the content of calcium oxide, the better the color. In nature, there are not many sources of calcium oxide, so animal bone meal is chosen as the source of calcium oxide.
The color of bone China is a natural milky white unique to natural bone powder. Generally speaking, porcelain containing 25% bone powder in raw materials can be called bone China, and internationally recognized bone powder content is above 40%. The best bone China generally contains 5 1% of high-quality bovine bone powder. Among them, bone powder accounts for more than 40%, and the color of the appliance is milky white, which belongs to high-grade bone porcelain. Only a few domestic manufacturers in Tangshan and Zibo produce and export.
After grouting, molding, gypsum mold dehydration, one-time firing, glaze firing, decal paper baking and other processes, it has become a porcelain with high whiteness, high transparency and fine porcelain quality. In the firing process of bone China, the requirements for its regularity, whiteness, transparency, thermal stability and other physical and chemical indicators are extremely high, resulting in a high rejection rate. Because of its exquisite materials, fine production and strict standards, its value is higher than other porcelain types. The unique firing process and the addition of bone carbon have eliminated the impurities in porcelain mud. Bone porcelain is whiter, more delicate, transparent, lighter, with fewer defects and thinner than ordinary porcelain. It has a special sense of cleanliness visually, and its strength is higher than that of ordinary porcelain and twice that of daily-use porcelain. The higher the content of bone powder, the lower the clay content, and the easier it is to burn and crack in the production process. It requires higher technology in molding, which increases the difficulty of firing, so it is more precious.
Someone has done such an experiment, putting four bone China cups under a Rolls-Royce wheel. These four crystal cups are enough to support the weight of the RV!
High-grade porcelain includes bone porcelain, shell porcelain and pearl china. Because of the high cost of shell porcelain and pearl china, there is almost no industrial production, so bone porcelain is recognized as the most high-grade porcelain in the world.

Among them, bone powder accounts for more than 40%, and the color of the appliance is milky white, which belongs to high-grade bone porcelain. More than 40% of the top European standard bone China tableware costs several thousand yuan. There are not many brands exporting high-quality bone China, such as Wedgewood, which has a history of more than 200 years abroad, and ZWZ Home, which has a long history in China, are all bone China products with bone powder content above 45%. Only a few domestic manufacturers in Tangshan and Zibo produce and export.

At present, bone China is generally a chemical formula, because there are not so many animal bone powders available.
Someone has done such an experiment, putting four bone China cups under a Rolls-Royce wheel. These four crystal cups are enough to support the weight of the RV!
High-grade porcelain includes bone porcelain, shell porcelain and pearl china. Because of the high cost of shell porcelain and pearl china, there is almost no industrial production, so bone porcelain is recognized as the most high-grade porcelain in the world.
Many people think that blue and white are exquisite and have bone China. In fact, the blue and white exquisite is very easy to burn out in the firing process, because it is carved holes in the blank as raw materials for bone China.
The source of bone China:
The English name of Bone China is "bone China", which is a porcelain with high whiteness, good transparency, fine porcelain and smooth glaze made by mixing animal ashes into ceramic raw materials. It is known as "as thin as paper, as white as jade, as bright as a mirror and as bright as a parallel".
Bone China was first produced in England. At first, its basic formula was six parts of ashes and four parts of porcelain stone. Later, it gradually developed into fifty parts of ashes, twenty-five parts of porcelain stone and twenty-five parts of clay. Until today, it has been considered as the standard formula in Britain.
Bone China is considered to be the highest grade porcelain variety in the world. According to international standards, bone China contains more than 25% of the ashes of herbivores, which is an environmentally friendly green consumer product. Compared with ordinary ceramics, the unique firing process and bone carbon content make bone China appear whiter, more delicate, more transparent and lighter. Ceramics originated in China, but bone China originated in England. It used to be a long-term special porcelain for the British royal family, and it was beautiful. Even now, bone China is a symbol of the owner's identity and status. Because cow bone powder can increase the hardness and transparency of porcelain, bone porcelain can be thinner than ordinary porcelain. Put the cup in a bright place to observe. Bone China products with fine composition, light transmission and no impurities are the first choice. Bone China, like ceramics, is graded, usually depending on the texture of the material, manufacturing technology and painting design. The higher the number of bone China, the more difficult it is to make and the more expensive the finished product is.
Characteristics of Erguci:
1 Beauty of appearance: Porcelain is delicate and transparent, with beautiful and elegant shape, jade-like color and colorful flowers.
High-grade: produced in Britain, it has long been a special porcelain for the British royal family and nobles. It is the only recognized high-grade porcelain in the world at present, which has dual values of use and art, is a symbol of rights and status, and is known as the king of porcelain.
3. Health products: animal bone charcoal is mainly used to make bone China, and the flower decoration and glaze of bone China are integrated, which does no harm to human body ... >; & gt
Question 5: What's the difference between a chemically made bone China bowl and a real bone China? The so-called chemical manufacturing of bone China refers to the bone China products generated by artificial chemical reaction of bone powder components, and the finished products do not contain animal natural bone powder, so it is called new bone China. Here is a detailed introduction to the differences between new bone China and bone China:
Animal bone meal
Animal bone meal is the product of vertebrate bones after degreasing and calcination. Its main component is hydroxyapatite, and a small amount of calcium fluoride, calcium carbonate, magnesium phosphate and so on. Bone meal used in production is made from the bones of cattle, sheep, pigs and other animals by cooking and degreasing at 900- 1000℃, then calcining at 900- 1300℃, fine grinding with a ball mill, washing with water or acid, removing iron and drying.
Synthetic bone meal
There are many synthetic methods of bone meal. At present, the most widely used method in China is Zibo's method. Its preparation method is that calcium hydroxide and phosphoric acid are neutralized and then calcined at 1280- 1300℃ to form a synthetic raw material containing animal bone meal components.
13 the difference between new bone China and bone China;
Origin: Bone China was successfully developed by Tangshan No.1 Porcelain Factory and Tangshan Ceramic Research Institute. The main producing area of new bone China is Zibo, Shandong Province, which was developed by Shandong Silicate Research and Design Institute.
Composition: The content of bone powder in bone China refers to the content of chemical substance "tricalcium phosphate".
Tricalcium phosphate in bone China is a natural bone powder in animal ashes, mainly bovine bone powder in Qinghai and Inner Mongolia, and calf bone powder of 2-4 years old is the best;
Tricalcium phosphate in new bone China is artificially synthesized. Its preparation method is that calcium hydroxide and phosphoric acid are neutralized and then calcined at 1280- 1300℃ to form a synthetic raw material containing animal bone meal components.
3. Bone powder: more than 40% bone powder is added to bone China; There is no bone powder added in the new bone China.
4. Production: Bone China is fired twice, with high-temperature plain firing and low-temperature glaze firing.
New bone China is fired at one time and glazed at low temperature.
5. Lead: The lead content of bone China is generally higher than that of new bone China, because bone China uses frit glaze in the secondary low-temperature glaze firing, and the frit is divided into lead-containing frit and lead-free frit. The lead content of new bone China is low.
Sixth, color: the color of bone China is natural milky white, commonly known as small yellow; The higher the content of bone meal, the more ivory it tends to be, and the lower the content of bone meal, the more yellow it becomes. The new bone China is made of a synthetic chemical raw material and some whitening agent.
Seven. Voice: Bone China collided with a draw, making a crisp "clang" and echoing. The longer the echo time, the more obvious the characteristics of bone China (the experimental effect of bone China bowl is more obvious); When the new bone China collided with other porcelain, it made a dull "ding" sound, and there was basically no response.
Eight, weight: bone China is the lightest; New bone China followed closely; White porcelain is the heaviest.
Nine, fetal quality: bone China fetal quality is thin; The fetal quality of new bone China is thicker.
X. appearance: the second firing regularity of bone China is high, and the glaze is bright; The first firing of new bone China is relatively the second.
Xi。 Light transmittance: bone China has good light transmittance; The new bone China has the second light transmittance.
12. Ceramics: Bone powder contained in bone China has low viscosity, so it is more difficult to fire complex ceramics than other ceramics.
Thirteen. Price: Generally speaking, the price of new bone China is higher than that of bone China, but it is more the result of horse racing in Tian Ji.
Because tricalcium phosphate in new bone China is artificially synthesized and can be produced mechanically, and tricalcium phosphate in bone China is a natural component in animal ashes, animals cannot be produced mechanically, and tricalcium phosphate in animal bone powder cannot be produced quantitatively, so the cost of grafting bone China is higher than that of new bone China. Secondly, because bone China contains bone powder, its viscosity is very low, so the manufacturing process is more difficult and the cost is higher than that of new bone China.
Summary: the same porcelain, but different varieties, and each has its own market, because it belongs to different varieties, there is no comparability.
Question 6: Variety and classification of bone China Detailed explanation and identification of bone China;
Bone China is considered to be the highest grade porcelain variety in the world. According to international standards, bone China contains more than 25% of the ashes of herbivores, which is an environmentally friendly green consumer product. Compared with ordinary ceramics, the unique firing process and bone carbon content make bone China appear whiter, more delicate, more transparent and lighter. Ceramics originated in China, but bone China originated in England. It used to be a long-term special porcelain for the British royal family, and it was beautiful. Even now, bone China is a symbol of the owner's identity and status. Because cow bone powder can increase the hardness and transparency of porcelain, bone porcelain can be thinner than ordinary porcelain. Put the cup in a bright place to observe. Bone China products with fine composition, light transmission and no impurities are the first choice. Bone China, like ceramics, is graded, usually depending on the texture of the material, manufacturing technology and painting design. The higher the number of bone China, the more difficult it is to make and the more expensive the finished product is. Bone China has many outstanding advantages: delicate texture, milky white, translucent under the light, and the most valuable thing is that it is much lighter than ordinary ceramics. In addition, gorgeous decoration makes bone China tableware complete. Each set has a poetic name, such as "Centennial Harmony", "Moonlight on the Lotus Pond" and "Elegant Rhyme in Clear Autumn", and the pattern of each set carries an expression. Light weight, strong light transmittance and soft color are all top grades. When you choose, the color turns yellow under the light, and there is a crisp sound when you knock. )
Bone China price:
Compared with our usual dishes, the price of brand-name bone China products is much higher. A porcelain bowl is about 260 yuan, and a saucer matching the bowl is about 300 yuan. A complete set of tableware for six people usually includes: a 9-inch flat plate for cold spelling; Four 7-inch flat plates for cold dishes; Four 7-inch soup plates with hot dishes; A big soup basin, two fish plates, six rice bowls, etc. A set costs about 5000 yuan or more. Of course, when buying, you can buy one by one and choose the dishes, cups and plates you need, so you don't have to stick to the whole set. White or set tableware with elegant patterns is the family's favorite.
Bone China maintenance:
Be sure to wash it by hand, not in the dishwasher. If you really don't want to wash by hand, choose a dishwasher with "porcelain crystal" washing function.
Don't put it in the microwave oven to heat it, or it will corrode Phnom Penh.
The PH value of emulsion must be between11-11.5.
When washing with clean water, the water temperature shall not exceed 80℃.
Do not immerse the hot cup directly in cold water, lest the temperature change too fast and damage the porcelain.
If there are scratches, you can polish them with toothpaste.
If there are tea stains, you can clean them with lemon juice or vinegar.
Question 7: What does bone China mean in ceramics? That is, bone powder porcelain is usually cow bone. This kind of porcelain is thin and beautiful in color.
The bone China in Tangshan, China is good. Or Tangshan bone China has mastered the technology because of export. This firing method was invented in England.
Question 8: The difference between bone China and ceramics The so-called bone China is a kind of ceramics. It was invented by the British in the18th century. It is named after adding about 30% of the ashes of herbivores (usually bovine bone powder) to its clay, and it is an environmentally friendly green consumer product.
The addition of ashes increases the hardness and transparency of porcelain, and its strength is higher than that of ordinary porcelain and twice that of daily-use porcelain. The unique firing process and the addition of bone carbon eliminate the impurities in the porcelain clay. Bone porcelain is whiter, more delicate, more transparent, lighter, less flawed and thinner than ordinary porcelain, and has a special sense of cleanliness visually. The higher the dosage of bone meal, the lower the clay composition, and the easier it is to burn and crack in the production process, which requires higher technology in molding and increases the difficulty of firing, so it is more precious.
The color of bone China is a natural milky white unique to natural bone powder. Generally speaking, porcelain containing 25% bone powder in raw materials can be called bone porcelain, but it is recognized that the best bone porcelain in the world generally contains 5 1% high-quality bovine bone powder. Among them, bone powder accounts for more than 40%, and the color of the appliance is milky white, which belongs to high-grade bone porcelain.
It is recommended to use ordinary porcelain every day. After all, bone China is expensive. General porcelain also has very good quality products. Sure, if you have money, suit yourself.
Question 9: What is bone China? Bone China? Bone China? What is bone China? Bone China is short for bone China. It is a kind of porcelain made of animal bone charcoal, clay, feldspar and timely as basic raw materials, which is fired twice by high-temperature plain firing and low-temperature glaze firing. The formation of bone China mainly depends on silica, alumina and calcium oxide. The higher the content of calcium oxide, the better the color. In nature, there are not many sources of calcium oxide, so animal bone meal is chosen as the source of calcium oxide. Bone China was invented by the British in 1794. It is named after adding the ashes of herbivores such as cattle and sheep to its clay (preferably bovine bone powder). Now bone China has become the focus of buying exquisite gifts in porcelain. Bone China is characterized by delicate and transparent porcelain, beautiful and generous shape, moist and bright color surface and colorful flower surface. Bone China was first born in England. For a long time, it has been a special porcelain for the British royal family and nobles. It is the only recognized advanced porcelain species in the world. It has the dual value of use and art, is a symbol of rights and status, and is known as the king of porcelain. The manufacturing process of bone China is complicated, and it needs to be fired twice. At present, only a few countries, such as Britain, China, Japanese, German, Russian and Thailand, produce bone China. The formation of bone China mainly depends on silica, alumina and calcium oxide. The higher the content of calcium oxide, the better the color. In nature, there are not many sources of calcium oxide, so animal bone meal is chosen as the source of calcium oxide. What is bone China? In fact, the so-called bone China is made of the ashes of herbivores (mainly Ca3(PO4)2), with high-quality kaolin, timely and other accessories, and glazed at 1280℃. Generally speaking, bone China can be called bone China when 25% bone powder is added to the raw materials, but it is recognized that the bone China with the best texture in the world today is bone powder content of 45%-5 1%, and cow bone is the best. The manufacturing process of bone China includes grouting, molding, gypsum mold dehydration, initial firing, glaze firing, decal paper baking and other processes. After high temperature firing, it becomes porcelain with high whiteness, high transparency and fine porcelain quality. In the firing process of bone China, the requirements for its integrity, whiteness, transparency, thermal stability and other physical and chemical indicators are extremely high, resulting in a high rejection rate. Because of its exquisite materials, fine production and strict standards, its value is higher than other porcelain types. The unique firing process and the addition of bone carbon have eliminated the impurities in porcelain mud. Bone porcelain is whiter, more delicate, transparent, lighter, with fewer defects and thinner than ordinary porcelain. It has a special sense of cleanliness visually, and its strength is higher than that of ordinary porcelain and twice that of daily-use porcelain. The higher the content of bone powder, the lower the clay content, and the easier it is to burn and crack in the production process. It requires higher technology in molding, which increases the difficulty of firing, so it is more precious.
