657. Chapter 657 The silver mirror three thousand years ago
To make glass, if you want to be more precise, you need to use soda ash, sandstone, limestone, dolomite, thenardite, and feldspar in a certain proportion and melt them at high temperature.
There are some things here that are not found in the mine. After all, the mine is not a treasure chest. You can get whatever you want.
Haitang could only settle for the next best thing, using only quartz sand and natural soda to synthesize the simplest and roughest glass. Even so, he believed that the effect of making a silver mirror would be hundreds of times better than a bronze mirror.
Haitang didn't learn this from books, but read it in idle books.
She remembered this little story:
According to modern chronology, it should be more than 3,000 years ago.
A European Phoenician merchant ship was loaded with the crystal mineral "natural soda" and sailed on the Belous River on the Mediterranean coast. Due to the low tide of the sea, the merchant ship ran aground.
So the crew members boarded the beach one after another. Some crew members also carried a large pot, brought in firewood, and used a few pieces of "natural soda" as a support for the large pot to cook on the beach.
After the crew finished their meal, the tide began to rise.
When they were about to pack up and board the ship to continue sailing, someone suddenly shouted: "Come and look, everyone, there are some crystal bright and sparkling things on the sand under the pot!"
The crew brought these shining objects to the ship for careful study.
They found that these shiny things had some quartz sand and melted natural soda stuck to them.
It turned out that these shiny things were the natural soda they used to make pot supports when cooking. Under the action of flames, the crystals were produced by a chemical reaction with the quartz sand on the beach. This was the earliest glass.
Later, the Phoenicians mixed quartz sand and natural soda together, and then melted them in a special furnace to make glass balls, which made the Phoenicians make a fortune.
Now, Bai Haitang has to follow the same method. As for the special furnace, a porcelain furnace will do. Fortunately, Datong got himself kaolin and feldspar from Shuilian Mountain, and the kiln Haitang who fired the porcelain furnace was made according to Shuilian Mountain's method.
After collecting everything, drying what needed to be dried, mashing what needed to be mashed, and processing what needed to be done, the crabapples began to pound in the room of the dye house.
Everything was as expected. Within a few days, not only was the porcelain furnace fired, but the natural soda and quartz sand melted by it did form a special crystal. It was not as clear and transparent as glass, but slightly turbid.
Through it, it does not affect the ability to see things outside the glass...
Begonia stroked it, glass, glass, it’s such a good thing, I made glass...
A feeling of emotion surged in my heart. Originally, producing glass was not a big deal, but these were all done with raw materials without conditions, environment, and tools, with only Haitang alone.
This is what makes Bai Haitang the most excited and excited, as if a chemist has discovered something new...
When firing the porcelain stove, Haitang also burned several warming basins and porcelain basins, preparing to give a few to Lamei's family and her own family, as well as her neighbor Aunt Li, whose milk Tiantian relied on before weaning.
, how can we forget this kindness?
Holding the glass, Begonia came to the sun. Through the warm sunshine of early winter, it felt even more intimate...
Lamei watched Haitang jump and jump, but she was in a daze. She didn't know how the thing in her hand made Sister Haitang so happy.
