Reputation depends on quality,  quality comes from Hard!


Alumina Ceramics:

Alumina ceramic refers to pottery with a layer of lime glaze on the surface. The main components of the glaze are silicon oxide, aluminum oxide, calcium oxide, sodium oxide, etc., which can be prepared by adding lime and clay, and it is in a glass state after melting. If some metal oxides such as copper oxide and cobalt oxide are added to the glaze, green and blue colors will appear after firing. The common Tang Sancai is glaze pottery.

Pottery is not a unique invention of China. Archaeological discoveries prove that many countries and regions in the world have invented pottery. However, China has made a big step forward on the basis of pottery--the earliest invention of porcelain, in human civilization. A glorious page was written in history.

Although porcelain and pottery are two different materials, there is a close relationship between the two. Porcelain could not have been invented separately without the experience of the invention of pottery and the continuous improvement of pottery making techniques. The invention of porcelain is our ancestors' long-term understanding of the performance of raw materials, summing up the firing technology, and accumulating rich experience in the long-term pottery making process, resulting in the change from quantitative to qualitative changes.
The firing temperature of pottery is generally lower than that of porcelain, the lowest can reach below 800 ℃, and the highest can reach about 1100 ℃. The firing temperature of porcelain is relatively high, most of which are above 1200 ° C, and some even reach about 1400 ° C.
