Knowledge-rich porcelain varieties of bone China

Recently, it has been found that bone China cups are very popular in the market. I am ignorant. I didn't know what bone China was, so I looked it up. I will share the results with you and tell you about bone China. What is bone China?

Bone China: referred to as bone China, also known as bone China, produced in Britain. It is generally believed that Josiah Spode (1755- 1827) was the first Englishman who successfully made bone China. Josia Spode directly mixed burnt bones with porcelain clay and mineral flux to become traditional hard porcelain raw materials, which was successfully tested in the early19th century. Later, he began to systematically study the formula for producing bone China. At the end of 182 1, the ratio of ashes to porcelain stone was "standardized". At that time, it was thought that porcelain with feldspar as flux and 46% ash was the best product.

The basic process 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. 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). 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 can be called bone China. On the other hand, the American standard is at least 25%. Characteristics of bone China

Bone China is exquisite in materials, fine in production and strict in standards, and requires extremely high indexes such as regularity, whiteness, transparency and thermal stability. Due to the complex process of high-grade bone porcelain, it is difficult to make ordinary daily-use porcelain, and its production technology is difficult to popularize.

Bone China is a high-grade British porcelain with a history of more than 300 years.

It is a symbol of power and status of palace treasures and aristocratic collections in history, and is favored by many buyers. Bone China, known as "porcelain", has gradually become a world ceramic treasure.

Varieties of bone China

New bone

NewBone china is generally called new bone. No one added the word China to the name of Canton Fair. It was originally an ordinary high-white porcelain, and the content of calcium oxide in the composition was slightly higher than that of ordinary porcelain, which had certain light transmittance. The clever manufacturer gave it a name of climbing the dragon and attaching the phoenix, called New Bone China. The main differences between it and bone China are as follows:
