More than 3,000 years ago, a European Phoenician merchant ship was loaded with crystal mineral "natural soda" and sailed on the Mediterranean coast of the Beirut River. Due to the ebb tide, the merchant ship was stranded. The crew then boarded the beach. Some crew members also brought large pots, moved firewood, and used a few "natural sodas" as a support for the cauldron to start the meal on the beach. After the crew finished eating, the tide began to rise. As they were preparing to pick up and embark on the boat to continue sailing, suddenly someone shouted: "We are all coming and seeing, there are some bright, sparkling things on the sand under the pot!" The crew took these glittering things to Carefully studied on board. They found that there was some quartz sand and melted natural soda on these shiny things. It turned out that these flashes of light are the natural sodas that they use as pot holders for cooking. They are the earliest glasses made by the chemical reaction of quartz sand on the beach under the effect of flames. Later, the Phoenicians pooled the quartz sand with the natural soda and then melted it in a special stove to make a glass ball, making the Phoenicians make a fortune. Around the 4th century, the Romans began to apply glass to doors and windows. By 1291, Italy's glass manufacturing technology has been very developed. “The glass manufacturing technology in our country must not be leaked out, and all the artisans who make the glass are brought together to produce glass!” In this way, the Italian glass craftsmen were sent to an isolated island to produce glass. They were in their lives. It is not allowed to leave this island. In 1688, a man named Naf invented the process of making large pieces of glass. Since then, glass has become a common item. The glass we use today is made from quartz sand, soda ash, feldspar and limestone at high temperatures. The non-crystalline solid material obtained by gradually increasing the viscosity of the melt during cooling. Brittle and transparent. There are quartz glass, silicate glass, soda lime glass, fluoride glass and so on. Usually refers to silicate glass, quartz sand, soda ash, feldspar and limestone as raw materials, after mixing, high-temperature melting, homogenization, processing forming, and then obtained by annealing. Widely used in construction, daily use, medical, chemical, electronics, instrumentation, nuclear engineering and other fields.
