What is bone china?
Bone china (Bonechina): referred to as bone china, also known as bone china, production began in the United Kingdom, and academic circles generally believe that it was the first to successfully produce bone china. The porcelain Englishman was Josiah Spode (1755-1827). Josiah Spode directly mixed calcined bones with china clay and mineral flux to become a traditional hard porcelain raw material, and successfully experimented in the early 19th century. He then began systematic research on the formula for producing bone china. At the end of 1821, the proportion of bone ash and porcelain stone was "standardized". At that time, it was believed that the best porcelain was produced using feldspar as a flux and containing bone ash. products. The basic process is a kind of porcelain that uses animal bone charcoal, clay, feldspar and quartz as basic raw materials, and is fired twice through high-temperature biscuit firing and low-temperature glaze firing. The two basic characteristics of bone china are the essential basis for distinguishing bone china from other porcelain. Feature 1: The bone char content is above 36 (national standard); Feature 2: It is made through secondary firing (bisque firing, glaze firing). According to the bone china standards set by the United Kingdom, it must contain 30% tricalcium phosphate from animal bones, and the finished product must be translucent to be called bone china. The American standard is at least 25 percent.

New bone china is generally called NewBone. No one at the Canton Fair added the word "china" after its name. It is a kind of ordinary high-white porcelain. The content of calcium oxide in the composition is slightly higher than that of ordinary porcelain, and it has a certain degree of light transmittance. The savvy manufacturers gave it a name that resembles a dragon and a phoenix, called new bone china. Its main differences from bone china (bone china) are as follows:
1. The raw materials used are different, more than 40% of bone powder is added to bone china, and no bone powder is added to new bone china;
2. Bone china is fired twice, and new bone china is fired once;

In short, new bone china is not a new variety of bone china. , but just borrowed the name.
Low bone china
Low bone china is a newly developed type of porcelain, which is somewhat related to bone china. Generally speaking, porcelain containing 10% bone powder in raw materials can be called low bone china, while orthopedic bone china generally contains about 40% bone powder; it has the same transparency, thinness and smoothness as bone china, but the price is higher than bone china. Porcelain is much cheaper. Therefore, it was welcomed by all middle and low-end hotels as soon as it was launched. It has the following characteristics:

4. It has light transmittance and light texture. It is mainly suitable for table setting in the front hall of mid-range hotels, table setting and kitchen use in high-end hotels.
Although low bone china has most of the characteristics of bone china and is very popular, there are still differences between the two:
1. The difference in bone powder content: Generally, bone powder containing 10% can be called low bone china, while bone china needs to contain more than 30%.
2. High bone china requires two firings, while low bone china only needs one firing.
3. The glaze of high bone china needs to be glazed with a spray gun after the product is bisque fired, while the glaze of low bone china only requires that the entire clay body be immersed in the glaze and then taken out to dry.
The above is the relevant knowledge about bone china that I have introduced to you. I hope you will like it. You need to choose a dishwasher with a "porcelain and crystal" washing function.
