Pottery is an appliance made of clay or clay by kneading and firing. Pottery has a long history, in the Neolithic age has seen a simple rough pottery. In ancient times, pottery was used as a daily necessities, and now it is generally collected as a handicraft. The invention of pottery is the beginning of man's first use of chemical changes to change the nature, and one of the signs of the development of human society from the Paleolithic age to the Neolithic age. It is generally believed that the earliest pottery was made by hand and burned in a bonfire. The firing time is short, but the highest temperature of the fire can be very high, about 900 ℃. The pottery was found in Jiatai mound in 6000 years ago. And it's fast. Clay mixed with sand, gravel, broken shells or broken pottery can be used to make bonfire ceramics, because they provide an open body so that water and other volatile components can easily leave. The coarser particles in the clay also play a role in limiting the internal shrinkage of the ceramic body when it is cooled. This process is carried out at a slow speed and reduces the possibility of thermal stress and fracture.
In the early days, the pottery made by bonfire was mainly round bottomed, which was intended to avoid sharp corners that could easily break. The earliest purposeful kilns were cave kilns or ditch kilns, which dug a hole in the ground and then paved it with fuel. The holes in the ground provide the best insulation for better control of the firing process. The pottery is well preserved and has a high value of cultural and historical collection.
