China is one of the first countries in the world to invent and use glass. According to the Chinese Academy of Building Materials and other units, the study of the glass walls and other cultural relics of the "Warring States Period" unearthed, as early as the 3rd century BC, China has already produced glass products. The production of flat glass in China was founded in 1904. In the Qing Dynasty, Lin Songtang, Xu Dinglin, Gu Enyuan and others established factories in Wuchang, Hubei, Suqian, Shandong, and Boshan, Shandong, and produced flat glass by artificial blowing and flattening. In 1909, Boshan Glass Factory produced more than 4,200 weight boxes of flat glass. As a symbol of modern glass industry production, the use of slotted vertical lead-up method to produce flat glass began in 1924, Qinhuangdao Yaohua Glass Factory, which produced an annual output of 127,000 weight boxes. In the next 20 years, China's flat glass production and management is mainly in the hands of foreigners, and the flat glass industry is developing slowly. Until 1949, there were only three flat glass factories in Yaohuang, Dalian and Shenyang in Qinhuangdao, with an annual output of 910,000 weight boxes.
China's glass siliceous raw material mining was developed from the development of the flat glass industry in 1949 after the founding of the People's Republic of China. Before 1949, all local glass factories were buying raw materials for small-scale mining. The siliceous materials used in the three flat glass factories were imported from Southeast Asia or the Korean Peninsula. After 1949, the flat glass factory near the Qinhuangdao Jiguanshan, Benxi Xiaopingdingshan and other quartz sandstone ( quartzite ) mine, through simple geological work after mining, began to use rock-based siliceous materials. In the early 1950s, the building materials system geological team began to carry out formal systematic geological work on the glass siliceous raw material mine. The first exploration was the Fangshan quartzite mine in Dianchi, Henan and the Leizijie quartz sandstone mine in Xiangtan, Hunan. Fangshan Mine was built in 1958 as China's first glass siliceous raw material mine with an annual output of 300,000 tons of ore, as a raw material base for Luoyang Glass Factory.
For more than 40 years, the state has invested a large amount of geological exploration work on glass siliceous raw materials. The geological team of building materials, geology and minerals systems, closely combined with the needs of the development of the glass industry, comprehensively explored quartz sandstone mines, quartzite mines, vein quartz mines and quartz sand mines, and developed siliceous raw materials and minerals in many ways. Found and explored a large number of minerals, such as: Benxi in Liaoning, Fengyang in Anhui, Hanzhong in Shaanxi, Qufu in Shanxi, Datong in Qinghai, etc.; Quartzite in Hunchun, Xinjiang, Hami, Xinjiang; Hebei County, Zanhuang, Shandong Weinan, Cangshan, Zhejiang Changxing, Huzhou, Jiangsu Suzhou, Hunan Shimen, Zhangpu, Sichuan Qixian, Yunnan Kunming and other places of quartz sandstone mine; and Jilin Shuangliao, Liaoning Songwu, Inner Mongolia Tongliao, Quartz sand deposits in Jiangsu Suqian, Gansu Lanzhou, Jiangxi Hukou, Shandong Rongcheng, Fujian Dongshan, Guangdong Huidong, Guangxi Beihai, and Hainan Oriental. Many mines have been exploited and utilized one by one, “one factory, one mine”, “one mine and multiple plants” or “one plant and multiple mines” to supply the raw materials needed by the glass plant, meeting the needs of the rapid development of China's glass industry in the past 40 years. There are also a number of reserve mines that can be used for future construction. [next]
Rich mineral resources have provided favorable conditions for the Chinese glass industry to flourish in the past 40 years. From 1949 to the present, China's flat glass industry, through the continuous technological transformation of enterprises, a large number of capital construction projects have been completed and put into production, production scale has been continuously expanded, and the company's appearance has undergone fundamental changes. Its development characteristics are: development is mainly based on float process, float, vertical lead, flat pull, calendering, various molding processes coexist, product quality is high and low, to meet the needs of different grades, the total output continues to grow at a high speed. According to the results of the third national industrial census, at the end of 1995, China produced a total of 193 million weight boxes of flat glass production capacity of various processes, various scales and various equipment levels, with a production capacity of 15.94 million weight boxes, plus 1996-1997. The added float glass production capacity is 46.6 million weight boxes. At the end of 1997, the estimated production capacity was approximately 239 million weight boxes and the output was 170 million weight boxes, of which float glass production was 106 million weight boxes, accounting for approximately 60%. In addition, the variety of products used in many daily-use glass factories has increased year by year. In 1997, the total output of daily-use glass was about 7.3 million tons. The total amount of flat glass and daily-use glass is 850 to 9 million tons of silicon raw materials. It is estimated that the Chinese glass industry will continue to develop steadily in the future. With the increase in demand for high-quality flat glass and high-grade daily-use glass, it will inevitably promote the development of siliceous material mining and mineral processing and processing industries.
