Do you know the history of glass

glass was initially solidified from acidic rocks ejected from volcanoes. About 3700 BC, the ancient Egyptians had made glass decorations and simple glassware. At that time, there was only colored glass. About 1000 BC, China made colorless glass. In the 12th century, commercial glass appeared and began to become industrial materials. In the 18th century, optical glass was made to meet the needs of developing telescopes. In 1873, Belgium first produced flat glass. In 1906, the United States produced a flat glass lead-in machine. Since then, with the industrialization and large-scale production of glass, glasses with various uses and properties have come out one after another. In modern times, glass has become an important material in the fields of daily life, production and science and technology

more than 3000 years ago, a European Phoenician merchant ship, loaded with crystalline mineral "natural soda", sailed on the berus River along the Mediterranean coast. Due to the ebb tide of the sea, the merchant ship ran aground

so the crew boarded the beach one after another. Some crew members also brought cauldrons and firewood, and used a few pieces of "natural soda" as the support of the cauldron to cook rice on the beach

the tide began to rise after the crew had finished their meal. When they were about to pack up and board the ship to continue sailing, Suddenly someone shouted loudly to reduce environmental pollution: "Come and see, there are some bright and glittering things on the sand under the pot

the crew took these glittering things to the ship and studied them carefully. They found that there were some quartz sand and melted natural soda on these glittering things. It turned out that the installation wizard would begin to copy the installation files to the hard disk; these glittering things were the natural Su that they used to make the support of the pot when cooking Under the action of flame, the crystal produced by chemical reaction with quartz sand on the beach is the earliest glass. Later, the Phoenicians mixed quartz sand with natural soda, and then melted it in a special stove to make glass balls, which made the Phoenicians a fortune

about the 4th century, the Romans began to apply glass to doors and windows. By 1291, Italian glass manufacturing technology had been very developed

"China's glass manufacturing technology must not be leaked out. All glass makers are gathered together to produce glass. 1

in this way, Italian glass artisans are sent to an isolated island to produce glass, and they are not allowed to leave the island in their life.

in 1688, a man named naff invented the process of making large pieces of glass, and from then on, glass has become ordinary objects.

we The glass used now is made of quartz sand, soda ash, feldspar and limestone through high temperature

an amorphous solid material obtained by gradually increasing the viscosity of the melt during cooling. It is brittle and transparent. There are quartz glass, silicate glass, sodium calcium glass, fluoride glass, etc. It usually refers to silicate glass, which is made of quartz sand, soda ash, feldspar and limestone. After mixing, high-temperature melting and homogenization, it is processed and formed, and then annealed with high-speed computing ability. It is widely used in construction, daily use, medical treatment, chemistry, electronics, instrumentation, nuclear engineering and other fields
