Glass is one of the oldest known materials. The earliest glass used by people is generally the natural glass that is formed when the volcanic eruption erupts and the hot magma ejects from the surface and rapidly condenses and hardens. In ancient Egypt and Mesopotamia, glass is well known. About 4,500 years ago, glass manufacturing technology was invented in Mesopotamia, mainly to make glass beads and other decorations. Around 1600 BC, Egypt had a formal glass handicraft industry, and the first batch produced glass beads and vases. However, due to the immature smelting process, the glass is still opaque, and it was not until 1300 BC that the glass could do a slightly transparent line. By the 17th and 18th centuries AD, the steam engine came out, and the machinery industry and the chemical industry have developed greatly. In particular, the technology of making soda ash by using salt as a raw material has been invented, which has greatly promoted the development of the glass industry. The regenerative pool furnace is used for glass melting and invented a semi-mechanical forming method. From 1880 to 1890, he invented the molding technology of the production of a small-mouth bottle by a blow-and-blow method. In 1900, the first bottle-making machine driven by an electric motor appeared. 1904~1905, United States M. J. Owens creates a fully automatic vacuum suction bottle machine. In 1915, the drip feeder was introduced, and the glass packaging entered a period of rapid development. In 1925, a determinant bottle-making machine appeared, producing a small-mouth bottle by blowing and blowing. In 1940, a large-mouth bottle was produced by a pressure-blowing method, and then the determinant bottle-making machine was continuously improved. In the 20th century, glass scientific research and production technology have developed extremely rapidly, and the glass industry has reached the level of mechanization and automation. In terms of production management and quality control, the use of electronic computers to carry out multi-station, centralized, real-time regulation and management of the entire production process. In recent years, glass bottles and tanks are developing towards thin wall lightweighting, gradually overcoming the shortcomings of glass bottles and cans in packaging applications, and making the glass bottle and can industry continue to develop, becoming an important part of the packaging industry.

    China's glass development has a long history. In ancient times, it was called glass, glaze, and glass. In modern times, it is also called material. It refers to the amorphous inorganic material obtained by cooling and solidifying the melt. It can be found from the remains of history that China has had glass ornaments in the 8th century BC. In the Western Zhou Dynasty more than 3,000 years ago, China's glass manufacturing technology reached a high level. In the Tang and Song Dynasties, there were hollow glass containers blown by blowpipes.

    Today, glass has become an indispensable product in modern people's daily life, production development, and scientific research. Its application range is expanding with the development of science and technology and the continuous improvement of people's living standards.
