The English name of bone china is bone china. It is the only kind of porcelain invented by foreign countries in history. It was invented by the British in 1794. It is a kind of porcelain which is made of animal bone charcoal, clay, feldspar and quartz as basic raw materials, and is fired twice by high-temperature biscuit firing and low-temperature glaze firing.

 

The Chinese historical book "Tao Ji" said that this kind of porcelain is "thin as paper, white as jade, bright as a mirror, and sound like a chime". The European saying is: "Thinner than paper, whiter than milk, more transparent than glass" (literal translation).

 

It is said that when it was first developed, this kind of porcelain was invaluable in Europe. A piece of china can even be exchanged for an army. What is even more amazing is that this kind of porcelain can be made into lamps, but it has a more fantastic effect than glass lamps.

 

Its light and transparent texture has been popular for hundreds of years, and today it has become a special tableware for high-end banquets such as state banquets, royal family banquets, and celebrity banquets.

The raw materials of Chinese porcelain are mainly kaolin, porcelain stone and a small amount of lime. The raw materials of bone china are added with 30-45% bone powder, and the porcelain after adding bone powder can be made thinner, so the bone china is crystal clear under the light, delicate and light, and has a good feel and look.

 

Why is bone china a noble in porcelain? The main reasons are as follows:

 

raw materials

 

Bone china uses animal bone charcoal, clay, feldspar and quartz as the basic raw materials. The British believe that 2-4-year-old calf bone is the best bone china, and cow bone is the best raw material.

craft

 

With good raw materials, good craftsmanship is even more needed, otherwise it will be ruined.

 

When the bone meal content reaches a certain proportion, the quality of the porcelain will be greatly improved, which is mainly reflected in the gloss and luster of the utensils. However, if the content exceeds a certain proportion, the composition of clay will be relatively reduced, the porcelain will become too soft, and it will be easier to crack during the production process. Higher technology is required in forming, which increases the difficulty of firing, so more precious.

firing

 

(1) The formed bone china is sintered at a high temperature of 1250°C. During the sintering process, due to the very large shrinkage rate of the bone china, the finished product will shrink by 20% after kiln firing (generally, the porcelain shrinks by 7%), so the shape is easily deformed. Plates, bowls, etc. must be placed on special bowls to cook for a long time.

 

(2) After that, check the shape, curvature and size. After grinding the surface, spray the glaze with a sprayer, and enter the kiln for glaze firing at 1150 °C.

coloring

 

The general coloring method is to paste transfer paper on the white finished product and bake it at 820°C. Manual coloring is time-consuming, but the texture of the picture is more flexible.

Ordinary porcelain products will be corroded by acid and alkali in daily use, and trace metals will overflow, which will affect human health over time. The bone china does not contain lead and cadmium. The in-glaze color and under-glaze color bone china is not only free of lead and cadmium overflow, but also the flower surface is not easy to wear and fall off. It is suitable for dishwashers, disinfection cabinets, and steamers. It is well-deserved. Green and healthy ceramics.

The reason why bone china is expensive is inseparable from its raw materials and craftsmanship. When choosing bone china, you must be careful to identify, here are a few ways to identify bone china~

 

Identification of bone china

 

The color of bone china

 

Bone china has a natural milky white color because it contains bone powder, and this feature cannot be imitated by any other porcelain species.

 

The main types of porcelain on the market today, such as white porcelain, shell porcelain, and pearl porcelain, are all pure white, and that pure white can be described as blue-white. Secondly, it is also bone china, and the degree of yellowing can tell the level of bone powder content in the bone china itself. For bone china, the content of bone powder is an important technical index to distinguish the grade of bone china. The yellow is very obvious.
