Product Description

Reputation depends on quality, quality comes from Hard!

Alumina Ceramics:

Alumina pottery is usually made of clay. The temperature of firing pottery is generally between 900 and 1050 ° C. If the temperature is too high, the pottery will be burnt and deformed. The texture of the pottery of the pottery is relatively loose, and there are many pores, so it has strong water absorption. The surface of ordinary pottery is unglazed, even with glaze, it is low temperature glaze.

The history of China's firing pottery is about 10,000 years. In the primitive society, pottery was first made into a certain shape by hand kneading. Later, it was developed to knead the clay into the same thickness of clay sticks. Then, the clay sticks were shaped into a certain shape, and the inside and outside were smoothed by hand . By the time of the patrilineal society, the rotation method appeared. After entering the feudal society, the molding method was invented, that is, the clay was filled into the mold and the full shape of the utensil was taken out. It has been speculated that the most primitive method of firing was the pile-and-fire method, where dried terracotta slabs were burned in open firewood. Six to seven thousand years ago, pottery was fired in pottery kiln.

Archeologists of cultural relics divide pottery into red, gray, pottery, white, painted, black and glazed pottery according to the color of pottery.

Red pottery is the most common type of pottery in primitive society. Its color is like red brick. This is when the kiln is fully supplied with gas to form an oxidizing atmosphere, so that the iron in the clay is converted into trivalent iron, and it appears red.
