The luminous cup of grape wine reminds you immediately if you want to drink Pipa. Don't laugh when you are lying drunk on the battlefield. How many people have fought in ancient times.
This song "Liangzhou Ci" not only brings us a sense of heroism, but also leaves us with a question: What is the luminous cup?
It is said that King Mu of Zhou went to a grand gathering in Yaochi at the invitation of the Queen Mother of the West. During the banquet, the Queen Mother of the West gave him a sparkling green wine glass, which was called the "Night-Light Always Full Cup". King Mu of Zhou could not put it down as if he had found a treasure. From then on, the "Luminous Cup" became famous throughout the ages. So, is a luminous cup the kind of cup that glows in the dark by itself?
Actually, this is not the case. There are several luminous mineral materials in the world: fluorite, apatite, scheelite, and diamond. There are two types of fluorite luminescence: fluorescence and phosphorescence. Fluorescence can still emit light temporarily after the light source is removed, while phosphorescence is an internal energy luminescence that can continue to emit light without an external light source. Luminescent pearls made of phosphorus-containing fluorite fall into this category.
But the luminous cup is neither fluorescent nor phosphorescent. It is carved and finely ground from pure natural Qilian Mountain jade with excellent texture. The luminous cup has a thin wall. When the cup is filled with wine, it reflects the moonlight. The moonlight shines through the cup wall and shines with the color of the wine. It emits a strange brilliance with the help of external light energy, hence the name "luminous cup".
The jade material used to make luminous cups can be divided into black jade, jasper, white jade, etc. according to color. The ink one is as black as lacquer; the blue one is as green as emerald; the white one is like suet. The color is elegant, the texture is delicate, the coolness of the snow-capped mountains is revealed in the warmth, and the crystal is shining with the light of wealth.
The production process of luminous cups is complicated, requiring 28 steps before and after. Currently, more than 30 shapes have been developed. The decoration of the luminous cup is naturally formed. It has stable physical properties, is heat and cold resistant, does not crack or explode. When the wine is put into the cup, the color and taste will be more mellow. In 2006, the luminous cup sculpture was included in the first batch of national intangible cultural heritage lists.
