Pottery): Pottery, which is a utensil made by kneading clay or terracotta into shapes and firing them. Pottery has a long history, and simple and rough pottery was first seen in the Neolithic period. Pottery was used as a daily commodity in ancient times and is now generally collected as a handicraft. The invention of pottery is the beginning of the earliest use of chemical changes to change natural properties, and is one of the symbols of the development of human society from the Paleolithic to the Neolithic period.
Porcelain): Porcelain is made of porcelain stone, kaolin, quartz stone, mullite, etc., and the exterior is coated with vitreous glaze or painted objects. The forming of porcelain should be fired at high temperature (about 1280 °C ~ 1400 °C) in the kiln, and the glaze color on the surface of the porcelain will undergo various chemical changes due to the difference in temperature, which is a treasure displayed by Chinese civilization. China is the homeland of porcelain, and porcelain was an important creation of the ancient working people. Xie Zhaoxuan recorded in "Five Miscellaneous Tricks": "Today's common saying that kiln ware is called a magnet instrument, and the kiln in Cizhou has the most, so it extends its name, such as silver is called Miti, ink is called chyme, and so on." "At that time, the "magnetic" kiln that appeared was caused by the largest production of Cizhou kiln. This is the earliest historical source found to use the name porcelain.
