Manufacturing technology of Houma Butterfly Cup

It takes a very complicated process to make such a beautiful cup. First of all, the selection of materials is very particular, and natural mineral jade is generally needed. After the material is selected, it must go through complicated processes such as cutting, grinding, finishing, polishing, sealing and assembly. This small cup must be tossed in your hand at least a hundred times. Because jade is cool, it is also affected by the climate in the production process, and it can only be cut and made when the weather is good. In the process of polishing, you can't do without water, and the feel is very important. A slight deviation will break the cup, which is a very delicate job.

After careful study and in-depth excavation, Zhou found that ancient artists used the ingenious optical principle of "the cup is full of butterflies, and the wine is dry and the butterflies are hidden". Regarding the principle, Zhou explained: "At the bottom of the cup, a butterfly is mounted on a thin spring. Butterflies tremble when the cup is slightly disturbed. In the center of the cup bottom, something similar to the convex lens is embedded. There is no wine in the cup, and the butterfly is not in the focus of the convex lens. When wine is poured into a cup, it acts as a concave lens. The convex lens and concave lens are combined into a compound convex lens. The butterfly falls in the focus of the compound convex lens, and the butterfly forms an enlarged virtual image through the compound convex lens, so that people can clearly see the enlarged butterfly. "

He selected the most beautiful butterfly from more than 10,000 kinds of butterflies in the world, and specially bought special materials from Hong Kong to make butterflies, which became the only wine set that could be developed and became a famous craft product at home and abroad.
