More than 3,000 years ago, a European Phoenician merchant ship loaded with crystalline mineral "natural soda" sailed on the Beluce River off the Mediterranean coast. As the sea ebb, merchant ships stranded.
So the crew have boarded the beach. Some seafarers also carried cauldrons, moved firewood, and used a few "natural soda" brackets to start cooking on the beach.
After the crew had finished their meals, the tide began to rise. When they were ready to pick it up and continue their voyage on board the ship, someone suddenly shouted: "Come and see, there are some bright, glittering things on the sand below the pot!
The crew brought these shimmering things to the boat and studied them carefully. They found that some of these shiny crystals stuck with quartz sand and melted natural soda. Originally, these flashing things were the natural soda they used to make the pot during cooking, and the crystals that were produced by the chemical reaction of the quartz sand on the beach under the influence of flame were the earliest glass. Later, the Phoenicians combined quartz sand with natural soda and melted in a special stove to make glass balls, which made the Phoenicians make a fortune.
Around the fourth century, the Romans began to apply glass to windows and doors. By 1291, Italy's glassmaking technology has been very well developed.
"China's glass manufacturing technology must not leak out, all the glass-making artisans are concentrated together to produce glass!"
In this way, Italian glass craftsmen were sent to an isolated island to produce glass, and they were not allowed to leave the island for the rest of their lives.
In 1688, a man named Naf invented the process of making large pieces of glass, from which time the glass became an ordinary item.
The glass we are using is made of quartz sand, soda ash, feldspar and limestone at high temperatures.
Melt in the cooling process gradually increased viscosity obtained from the non-crystalline solid material. Sexually brittle and transparent. Quartz glass, silicate glass, soda-lime glass, fluoride glass. Usually refers to silicate glass, quartz sand, soda ash, feldspar and limestone as raw materials, after mixing, high temperature melting, homogenization, processing and forming, and then obtained by annealing. Widely used in construction, household, medical, chemical, electronics, instrumentation, nuclear engineering and other fields.
