One of Dehua porcelain varieties

Bone China is commonly used in dishes, and most people only know blue and white porcelain and bone China commonly used in dishes. There are many different kinds of porcelain. What's the difference between suet jade porcelain and bone porcelain?

Then, let's take a look at this issue of Dehua porcelain!

Sheep fat jade porcelain, that is, Dehua kiln white porcelain, is not only different from the northern white kiln of Tang and Song Dynasties, but also different from Jingdezhen blue and white porcelain. The porcelain clay produced near Dehua Kiln is soft in texture, low in iron content and high in potassium content. The vessels made of this raw material are white and moist in glaze, like coagulated fat, such as beautiful jade. In the sun, it is translucent lard-like, looming pink or milky white, so it is called "sheep fat jade".

Commonly known as "ivory white", it was called "the pearl of porcelain altar" by the French after being sold to Europe. The texture and luster are similar to the best of nephrite-white jade sheep fat porcelain. The firing of suet jade porcelain is very difficult and the process is complicated. Usually, only one finished product can be produced by firing multiple pieces, and the qualification rate of large-scale finished products is lower.

Almost harsh manufacturing technology and extremely low yield show the scarcity and preciousness of the best suet jade porcelain. It not only symbolizes the gentleman's moral character of "benevolence, righteousness, wisdom, courage and purity", but also symbolizes the secular feelings of "beauty, preciousness, auspiciousness, gentleness and tranquility". In the powerful Tang Dynasty, it was famous all over the world as a tribute. In the Qing Dynasty, suet jade porcelain reached its peak and became the most brilliant point in the history of China ceramics.

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. The two basic characteristics of bone China are the fundamental basis for distinguishing bone China from other porcelains. Feature 1: the content of bone charcoal is above 36% (national standard); Feature 2: secondary firing (plain firing and glaze firing).

Porcelain is delicate and transparent, with beautiful and elegant shape, moist and jade-like color surface and colorful flower surface. Calcium oxide is mainly used to make bone China. The floral decoration and glaze of bone China are integrated, and lead and cadmium are not harmful to human body. Can be called "celadon", long-term use is beneficial to human health.
