Differences between Bone Porcelain and Ordinary Porcelain

Ceramic Mug    From:Xinxiang Ceramic Mug Manufacturers     2019-3-11
From Ceramic Mug Manufacturer,Bone China, the English name of bone china, was invented by the British in 1794 and is recognized as the highest-grade porcelain in the world. Bone China is made by adding herbivorous animal bone powder to the clay and firing it twice with high temperature vegetarian firing and low temperature glaze firing. It is known as thin as paper, white as jade, bright as a mirror, and sound like a gown. Its color and luster become natural milky white unique to natural bone powder. Bone porcelain has been the best of all ceramics since it came out 300 years ago. It has long been the exclusive ceramics of the British Royal and noble. It is the only recognized high-grade ceramics in the world. It has dual value of use and art. It is a symbol of rights and status and is known as the king of ceramics. Up to now, Bone China is still a symbol of the identity and status of the owner with its noble and gorgeous quality.

Bone China is produced only in Britain, China, Japan, Germany, Russia and Thailand because of its complex technology, exquisite materials, narrow firing range and great difficulty in production. Among them, Tangshan is the main producing area in China, and Zibo, Chaozhou and Jingdezhen are also produced in a small part. Among them, Tangshan's Haigrei, Longda and Red Rose have the best output (depending on export, reliable quality), and are well-known brands in China. Most of the others are small factories. Zibo, Shandong and Chaozhou, Guangdong are mainly natural bone meal replaced by synthetic materials developed by Zibo Silicate Research Institute. They contain a lot of chemical ingredients and have whiter porcelain, but they are harmful to human body. They are called new bone china in the industry. Jingdezhen mainly produces blue and white porcelain and vase ceramics, which do not produce bone china. Because the ten local ceramics factories have already gone bankrupt, they are now purchasing white embryos from Tangshan and doing manual processing. Most of them are manufactured by family workshops, so the quality can not be guaranteed.

Tangshan, known as the capital of porcelain in the north, is the birthplace and main production base of Bone China in China. Tangshan is the real porcelain capital of northern China. As early as 1964, it began the research and development of Bone China and succeeded in 1973. It is the first one in China. It fills the gap in the production of high-grade porcelain in China and opens a new era for the development of bone china. Today, more than 80% of the domestic and export products of Bone China come from Tangshan, which shows the strength of its bone china industry. As a result, Tangshan has won the reputation of the Northern Porcelain Capital, and has also become the fixed host of China's Ceramic Exposition.

In the firing process of bone china, the physical and chemical indexes such as regularity, whiteness, transparency, thermal stability and so on are required to be very high, so the reject rate is very high. Because of exquisite materials, fine production and strict standards, the value is higher than other kinds of ceramics. With the unique firing process and the addition of bone carbon, the impurities in the clay are eliminated. Bone porcelain appears to be more white, delicate, transparent, lightweight, with few defects. It is thinner than ordinary porcelain, and has a special sense of visual cleanliness. Its strength is twice as high as that of ordinary porcelain. The higher the content of bone meal, the lower the composition of clay, the easier it is to crack in the process of making, the higher the technology is needed in forming, which increases the difficulty of firing, so it is more precious.

Animal bone charcoal is the main choice for making bone china. Bone porcelain decoration and glaze melt into one, without harmful lead and cadmium to human body. At the same time, because Tangshan Bone China has always been mainly exported, and because of the basic guarantee of European and American society, the safety requirements of utensils directly used by human body are very high, so the bone porcelain produced by big factories such as Tangshan Haigrey, Longda and Red Rose are truly green and environmental protection porcelain.

Bone China mug is the world's recognized top-grade porcelain, but why are some bone china tableware cheaper than high-white porcelain? Because these very cheap are synthetic new bone china, which does not add natural bone meal, but natural bone meal replaced by synthetic material developed by Zibo Silicate Research Institute, which contains a large number of chemical ingredients, harmful to human body, which is called new bone in the industry. Porcelain.

New Bone China cup is originally a kind of ordinary high-white porcelain. The content of calcium oxide in its composition is slightly higher than that of ordinary porcelain. It has a certain transmittance. Smart manufacturers have given it the name of Panlong Fufeng, which is called New Bone Porcelain. Its main difference from Bone China is as follows:

1. Different raw materials were used. More than 40% bone powder was added to bone china and no bone powder was added to new bone china.

Bone China was fired many times and new bone china was fired once.

3. Bone porcelain has softer whiteness, higher transparency, lighter porcelain and much better appearance than new bone porcelain.

6. The washing PH value must be between 11-11.5.

7. When washed with clean water, the water temperature does not exceed 80 degrees Celsius.

9. If there are scratches, you can use toothpaste to polish slightly.

10. If there is tea stain, it can be washed with lemon juice or vinegar.
