Crossing the Unknown Country

Chapter 278 Wang Xiaohu Makes Colored Glaze

Su He did not go home, but went directly to the teahouse. These days, she had asked the staff to find a carpenter to repaint the tables, chairs and benches, so that there would be no mottled marks. The walls were all freshly painted, and she also added a color to the white lime in a unique way, which was a very light yellow, using the paint that her master used to paint, which was very comfortable to look at.

She didn't dare to use dark colors, because the lighting here was too poor, and only bright colors could keep the room from getting dark at night. She replaced all the windows with oil paper, and used a translucent glass sheet in the middle. When she produced more in the future, she would replace all of them.

She had already found time to write down the method of making glass and gave it to Wang Xiaohu, asking him to find someone to make a trial. He promised that if it was made, he would let her use it first. There had always been colored glaze in this dynasty, but it was only in the hands of the aristocratic families, and the princes and nobles had to pay a lot of money to buy it.

Most of the colored glaze is used to make jewelry and ornaments, and it is not used to make window paper. The cost is too high and no one uses it. No one wants to do this. However, some people have made small screens, which are said to be very expensive and can only be used in the palace.

Wang Xiaohu was shocked when he saw the production method written by Su He. This little Su He really found a treasure. It turns out that alkali is the most important part of the process, and there is also the commonly used limestone, plus the sand. The more white and transparent good stones left after washing, the more transparent the glass will be. If you want color, you can add metal to change the color.

Things that were difficult for Su He to do were easy for Wang Xiaohu to do. What they lacked the most were people and places, but prescriptions. He took the prescription written by Su He to see General Wang An, who read Su He's writing carefully and laughed heartily.

After he finished laughing, he said, "Xiao Suhe is giving us a golden doll! Xiaohu, go find someone to try to make it according to the recipe, there shouldn't be any problem. Find a few blacksmiths and lime burners, they all know how to burn things."

It didn't take Wang Xiaohu and his team long to make the colored glaze, and they were now experimenting with making purer glass, because Su He had written that if they used some transparent quartz stones, they could make more transparent glass.

They had prepared some pressed colored glass, and Suhe Teahouse could just take it away whenever it was needed. They also planned to have Suhe Teahouse advertise for them, and Wang Xiaohu estimated that this would trigger a buying craze in the city.

They are organizing people to increase shipments. The cost is not high but the price is not low. He has seen the silver pouring in. This year, the brothers in the barracks will have a much better life. The general has silver, which means they can have more military rations.

Of course, Su He still had many drawings that she hadn't given them. There were too many things that Liuli could make. If she had it, Su He thought she could try to make a lamp. If a light bulb could be made, the battery would be easy to make. Even fruit could light up the light bulb, and she had solar energy.

She didn't bring her own solar cooker with her, and hid it in the basement. She spent a lot of money to make it, and although it doesn't seem expensive now, it is very practical and convenient for drinking hot water at home. Sometimes she also uses it to cook, but she can't cook too much.

Of course, light bulbs must use tungsten filaments. In this era, there should be tungsten ore, which should be called heavy stone. According to historical records, it was used in weapons and armor. Su He could only think about these things, and she had not yet figured out how to do them. This knowledge was just a general impression, and she had no concrete image in her mind.

Her impression of light bulbs is that when she was a child, if the light bulbs were not bright, if they were just broken, her father would take the light bulbs and turn them around to connect the tungsten filaments inside. As long as they could be connected, they could still be used for a while. This way, they could postpone buying light bulbs for a while and save money for the family.

She also took a discarded light bulb and looked at it. The tungsten filament inside was softly attached to the copper wire. It was fine if it broke and shook for a while, but it would not work if it broke too many times.

The main issue is how to make tungsten wire. Tungsten is as hard as diamond and has a melting point of over 3,400 degrees. It is very difficult to make. Tungsten is probably not something that ordinary people can get their hands on, and General Wang An probably has a hard time getting it either.
