1171. Chapter 1171: 1171 Self-made glass in distress
First, Haitang mixed the fine powder raw materials for making glass according to a certain proportion. The mixing ratio did not need to be too precise, although Lao Bai had already brought a scale.
The typical glass ratio is about 65% quartz sand, 20% soda ash and 15% lime. Then Haitang puts the mixed materials in the ironware on the bag cover and puts the ironware
Buried among the charcoal blocks.
You can also use containers made of clay or graphite. Here, Lao Bai got iron. Blowing air from the bottom of the fire will help increase the temperature of the fire, but be careful. If the temperature of the fire is too high,
The utensils may melt with the glassware, so Lao Bai did one of the most important tasks, mastering the heat, and worked as a helper for Begonia for a long time. He has almost practiced it. This means that he has never eaten pork, but he has seen pigs run away.
.
After the glass is formed, use a long iron rod to take it out of the container. Because the glass is very viscous, Haitang uses the iron rod to pick it up and roll it up on the iron rod to take it out. Then move the glass to the furnace.
If you want to make glass with patterns on both sides of the mold preheated by fire, you need a mold divided into two halves, and press the upper part firmly against the soft glass.
Lao Bai watched this process happily.
It’s so fashionable to have glass windows!
After the glass was formed, Haitang allowed the mold and glass to cool slowly for a few hours, then covered the grill with the lid and let the fire slowly extinguish itself.
When Lao Bai held the glass, I felt so happy. Although it was a little small, I would like to make more pieces and put them together in the future. It would be better than the stiff paper. At least this one is transparent and can be exposed to the sun.
The sun promotes the synthesis of vitamin D!
Lao Bai showed off about the glass for quite some time.
He said that his daughter was a great chemist, which made Haitang blush for a while. She just knew some chemistry knowledge, could copy the gourd, and was thousands of miles away from chemists. She was called a person who could add new species to the periodic table of elements.
As a chemist in college, I am just a mediocre little character...
But in the eyes of a father, a daughter will always be great.
"Daughter, please give me some rope." One day, Lao Bai's demand became stronger and stronger.
"Isn't there a hemp rope? It's thick and thin and long and short. It's all in your house." Haitang said.
"The rope is not elastic and difficult to use. We are not pursuing the retro style. Now we are pursuing fashion. You can think of a way." Lao Bai gave the problem to Haitang.
Haitang thought for a moment, okay, it seems that out of his selfless love for her father, she did this for him.
"Then get the nylon rope early." Haitang said.
Lao Bai clapped his hands and applauded.
Helping Haitang prepare things is what he must do.
Haitang thought for a while and realized that this nylon rope is a kind of artificial synthetic fiber. It is actually the first artificial synthetic fiber invented by mankind. In 1938, the American DuPont Company, which was originally famous for the production of gunpowder, disclosed an idea that made a difference in the history of sock knitting.
Undoubtedly the most important invention, nylon.
Nylon was neither discovered by accident nor extracted from natural raw materials. It is a designed material with a purpose, based on an understanding of polymer chemistry and a strong desire to fill the market gap in the sock industry.
