Four types of ceramic cups

1. Bone china (45%, 36%):

The basic craft is a kind of porcelain made of animal bone charcoal, clay, feldspar and quartz as the basic raw materials, which are fired twice by 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 china. Feature 1: The bone char content is more than 36% (national standard); Feature 2: It is made by secondary firing (bisque firing, glaze firing).

According to the bone china standard set by the United Kingdom, it contains 30% tricalcium phosphate from animal bones, and the finished product is light-transmitting, so it is called bone china. The American standard is at least 25 percent.

2.porcelain:

On the basis of the temperature of pottery making, adding fire and heating, the pottery becomes porcelain. The difference between pottery and porcelain lies in the difference of raw soil and temperature. The firing temperature of pottery is 800-1000 degrees, and the porcelain is fired at a temperature of 1300-1400 degrees with kaolin. )

There is also a kind of jade porcelain, which is made of mineral rocks and finely honed by modern nanotechnology. Different from traditional ceramics, in a general sense, jade porcelain refers to mineral porcelain, also known as mineral powder porcelain.

3. Enamel:

Seeing this, there must be many friends who feel nostalgic. In fact, enamel is an inorganic glass enamel that is coated on the surface of the metal substrate. Enameling on the metal surface can prevent the metal from rusting, so that the metal will not form an oxide layer on the surface when it is heated, and it can resist the erosion of various liquids.

Enamel products are not only safe and non-toxic, easy to wash and clean, but also have the strength of metal, the gorgeous appearance of enamel and the performance of chemical resistance. It can be widely used as eating utensils and washing utensils used in daily life, and under specific conditions, the enamel coating on the metal body shows excellent properties such as high hardness, high temperature resistance, wear resistance and insulation, so Enamel products have a wider range of uses

4. Ceramics:

Ceramics are materials and various products made of clay as the main raw material and various natural minerals through crushing, kneading, molding and calcining.

People call a kind of clay made of clay and fired at high temperature in a special kiln called ceramics, and its main raw materials are silicate minerals (such as clay, quartz, etc.) taken from nature. Ceramic is a general term for pottery and porcelain. The traditional concept of ceramics refers to all artificial industrial products that use inorganic non-metallic minerals such as clay as raw materials.
