The luminous cup, as the name suggests, will shine in the moonlight in the night. There is a poem in the Tang Dynasty: the grape wine wine luminous cup, want to drink immediately. Drunk lying in the sand field Jun Mo laughed, the ancients came to fight a few people back. Jiuquan Luminous Cup is a famous specialty of Gansu Jiuquan. It is a valuable drinking utensil with a long history. On May 20, 2006, Jiuquan Luguang Cup was approved by the State Council to be included in the first batch of national intangible cultural heritage.

First, the characteristics of Jiuquan luminous cup The luminous cup does not shine, it needs external light to produce that strange effect. The Jiuquan Luminous Cup is made of fine Qilian Mountain jade. Its texture is natural, the cup is thin like paper, the light is like a mirror, the inside and the outside are smooth, the jade is transparent and bright, and it is used for its sake, sweet and sweet, and it will remain unchanged for a long time. It is in the moonlight, and there is a strange brilliance in the cup. The characteristics of the luminous cup are: high temperature resistance, cold resistance, hot wine not fried, cold wine not cracked, and the impact is not broken. For example, at night, facing the bright moonlight, pouring the wine into the cup, the cup suddenly shines, the brilliance is radiant, and it is refreshing and refreshing. Second, the production process of Jiuquan luminous cup The production of luminous cup has to go through more than 30 complicated processes, the process is complex, and the production is excellent. First of all, we must choose the materials, choose the good materials, and the superior materials can achieve the effect of the "wine pan luminous cup". According to the size of the wine glass, the material is cut into different shapes, made into a cylinder, and then cut into a blank according to a certain size. The blank is produced in five steps. The finished blank is cut and coarsely ground, and the initial shape of the luminous cup is formed. The initial type is produced through four processes, then the crucible, which requires five processes. After the completion of this process, the luminous cup is basically formed, and the remaining is 14 steps of fine grinding, punching, grinding, stretching, polishing, and ironing. Finally, it is polished with a ponytail net to form a crystal clear luminous cup. The wine glass is required to be as thin as paper, high, thick, thin, thick, and the surface is smooth and delicate. Third, the identification method of Jiuquan luminous cup 1, eye view: genuine luminous cup body smooth and translucent, natural texture, pure color, dark green or emerald green, no cracks and adhesion marks. Inferior luminous cups are dull, poorly transmissive, and have fine cracks or broken bond marks. 2, feel: the surface of the authentic luminous cup is smooth and delicate, with a soft jade texture, no scratches and processing marks. The inferior luminous cup has a rough surface, waxy stains, obvious scratches or processing marks. 3, grade difference: divided into boutique, excellent products, first-class products, qualified products. The higher the level, the stronger the brightness of the cup, the better the light transmission, the brighter the color, the higher the value. Fourth, the legend of the luminous cup It is said that in the seventh century BC, Zhou Muwang was in power. At that time, a small country in the Western Region gave gifts to the DPRK in order to seek peaceful coexistence. In the first year, the envoys went to Hajj with the local Hetian jade from Xinjiang. Zhou Muwang saw the jade, Longyan Joy, and hospitality to the Envoy and his entourage. In the second year, the envoys were concocted in the same way, and they chose the best jade to contribute. However, Zhou Muwang’s reaction was very cold. After returning to the country, he told the king about Zhou Muwang’s attitude and discussed how he could please Zhou Muwang’s favor. At this point, it was suggested that jade could be made into a wine vessel. Because Zhou Muwang likes to drink alcohol and make fine wines with fine jade, it should be a happy thing for Zhou Muwang. Sure enough, in the third year, Zhou Muwang was very happy when a crystal-clear, thin, flapped cup was placed in front of Zhou Muwang. Especially when the cup is full of red wine, under the moonlight, sparkling, it is beautiful. Zhou Muwang immediately ordered the awarding envoy. The Luminous Cup was born from then on, hence the name. V. Variety of Jiuquan luminous cups Traditional luminous cups have large, medium and small goblets, flat bottom cups, beer mugs, micro cups, and three-bubble jade bowls. There are more than 80 varieties of antique cups, such as Jue Cup, Feng Cup, Niu Tou, Yi, Shuangfeng Cup, Shuanglong Haicang Cup and Wine, Tea Set, Jade Carving Craft Pendant, which are treasures for tourism commemoration and gifts for relatives and friends.

Technical requirements for the quality of Jiuquan Luminous Cup 1. The cup is made of Jiuquan jade that is protected by the protection object. Second, the main raw materials (Jiuquan jade) requires the main mineral components of jade: serpentine (Mg, Fe, Ni) 3Si2O5 (OH) 4, the structure is tight, the Mohs hardness is not less than 4 degrees, the density is 2.57 (+0.23 , -0.13) g/cm3. Bright colors, mainly green, dark green, yellow green, etc., dense block, grease luster, translucent - transparent (1mm polished), no cracks, impurities, cotton, stone bars should not be greater than 0.5% of the bar volume. Third, the management system in accordance with the requirements of the Jiuquan luminous cup traceability protection system, establish a traceability system, the mining, transportation, processing, and sales of the raw materials of the luminous cup can be traceable. Fourth, the processing technology (a) process flow drill bar material → fixed length → open blank → head drill → two drills → fixed bottom → tie cup → cup → cup → head 砣 → two 砣 → three 砣 → clear bottom → pull Help → chute → rough grinding → topping cup → fine grinding → polishing → hot wax (2) key process requirements 1. Fixed length: the bar material is cut into jade according to the product size, and the jade blank size is required ≥ product size 5mm. 2. Drilling (head drill, two drills, bottoming): According to the specifications of the vessel, the drill bit is used for head drilling and second drilling, and the bottom of the jade is drilled and shaped. 3. Tie cup: According to the cup type, the excess part is cut off with the diamond powder slice, and it is required to cut eight pieces. The shape is well-proportioned and has an octagonal pyramid shape. 4. Cup: The cup is ground with a grinding wheel, which requires the cup to be flat, well-proportioned and without corners. 5. Milling cup: According to the specification of the vessel, the cup is ground by a grinding wheel, and the surface is required to be flat and without corners. (Applicable only to the production process of the high-seat cup) 6. 掏膛: 掏膛 掏膛 砣, 二砣, 三砣, 清底, 拉帮. The inside of the cup body is required to be flat, without angular edges, and the cup wall is thin and symmetrical, and the thickness is not less than 2 mm. 7. Tuobei: Flatten the cup and cup bottom, require the cup mouth and cup bottom to be flat, and the cup mouth is 90 degrees perpendicular to the cup body. 8. Fine grinding: Smoothing the inside and outside of the molded luminous cup with fine mortar, requiring smooth and smooth inside and outside of the luminous cup. 9. Polishing: Polishing the luminous cup with a polishing material requires light and lubrication inside and outside the cup. The cup is transparent or translucent with no trace of processing. V. Quality characteristics (1) Sensory characteristics 1. The belly is required to be evenly arranged, the thickness is uniform and flat, the cup mouth is smooth, the edge line is smooth, and the depth is consistent. 2. The color is pure, dark green or emerald green, and the pattern is natural. 3. It has strong finish, no processing marks, nourish and flatten, and the surface is soft and jade-like after polishing, and the hand feels smooth.
