Beans are bowl-shaped lighting tools, and lamps are bowl-shaped lighting tools, but there is a small pointed cone at the bottom of the bowl called Zhi Ding. This small change has become the dividing line between beans and lights.
During the Warring States period, the earliest candles began to appear. But the candles at that time were different from the candles now, and their shapes were not very regular, so it was difficult to support and stand. The wise ancients made a sharp cone at the bottom of the bean, and put an irregular candle on this sharp cone, so that the candle could stand steadily.
From bean to lamp, it is not an overnight process, but a gradual process. This disc is probably the prototype of lamps in the Warring States period, and the pointed cone indicates that it was used for lighting at that time. The appearance of Zhi Ding officially opened the history of lamps, and since then, the history of lamps has changed from beans to lamps.
Where there is light, there is human civilization. Tens of thousands of years ago, human beings knew to use the fire of nature to keep out the cold, barbecue and light. More than 3000 years ago, humans began to carry candles with simple lamps and write the history of civilization. From rough stone lamps to bronze lamps, ceramic lamps to modern electric lamps, the historical changes of lamps are deeply branded with the times and are also the epitome of social economy and culture.
Lamps and lanterns from bamboo, wood, iron, copper, jade, silver to ceramics reflect the evolution and development of texture.
