At noon the next day, the fleet returned to Jiangzhou Fucheng with smooth sailing.
The fleet docked at the new pier, Song Yang and others got off the ship, and Fang Zhe, Yu Ming and others also came to pick up the ship.
Fang Zhe came back at noon the day before yesterday. Song Yang was delayed in Yuzhang for a few days, but Fang Zhe and the others got home first.
"My lord, it's been a hard journey."
"Thank you for your hard work, everyone! Let's go and see the injured soldiers and the families of the fallen soldiers first."
Song Yang got off the boat and said with a serious face.
He had been thinking about it on the boat, so he went to take a look as soon as he got off the boat.
During this expedition to Hongzhou, the Renaissance Army also suffered casualties.
There were a total of 326 casualties, including 121 killed in action.
It was originally one hundred and seventeen, but there were four infected wounds on the way.
Dr. Lu tried his best, but unfortunately he still could not save his life.
Lu Jimin went to Liuyang with Xue Jing and Lin Yong. With the troops withdrawn from Liuyang, Lin Yong's injury was much better, so he asked Lu Jimin to return to Jiangzhou.
Lu Jimin walked from Liuyang to Jiangzhou and caught up with Yu Ming's brigade in Wuning, so he devoted himself to the medical work of the wounded soldiers.
"The main problem now is anti-infection. Injured soldiers are in such a hurry that everyone has to have their limbs amputated due to wound infection."
"It would be great if there was penicillin. It seems that when I have some free time, I will have to get the penicillin out."
"Yes, Your Majesty. This war is the largest casualty since the natural disaster. It also shows that our Jiangzhou's medical conditions cannot keep up. If we can really develop the kind of anti-infective drugs you mentioned, it will be very beneficial to the wounded."
It’s great news for me.”
After seeing the wounded soldiers, Song Yang felt depressed.
There were more than 200 injured, including more than 30 who were seriously injured. They were lying on the bed and living lifelessly, which made Song Yang feel heavy.
The desire for penicillin became even more urgent.
Lu Jimin often heard Song Yang mention the usefulness of penicillin, so he was looking forward to this magical drug.
"The matter of penicillin should be put on the agenda. I'll have people prepare things in a while, and we can learn more about how to test penicillin together."
"Yes, Your Majesty. I will definitely do my best to assist Your Majesty in developing penicillin!"
Although it was determined to develop penicillin, the biggest problem now was equipment.
Although there are some glass products in Daqian, most of them are just glass beads and the like, which can only be used as handicrafts.
There is not even a utensil like a cup.
Moreover, the glass produced by the existing glass process has many impurities and is brittle, making it impossible to manufacture test tube beakers.
Without these equipment, it would be even more difficult to trial-produce penicillin.
"There are glass craftsmen."
After paying condolences to the families of the fallen soldiers and implementing the due treatment, Song Yang immediately found Fang Zhe.
Fang Zhe shook his head. This thing was originally not in demand by the public, let alone now.
Before the natural disaster, there was not a single glass craftsman in Jiangzhou.
"Looks like I have to do it myself!"
"Does the prince want to make glass?" Shen Xiaowan said as she wiped her tears.
Just after getting off the ship, Song Yang went to the wounded barracks and the homes of the fallen soldiers.
Shen Dan and Shen Xiaowan also followed behind.
After reading so much, the girl also felt the same and cried.
It wasn't until everything was done and Song Yang and Fang Zhe discussed the glass issue that Shen Xiaowan finally calmed down.
"Yeah. I need to make some tools. Do you know glass?" Song Yang looked at Shen Xiaowan with red eyes and said.
"Of course I do. Not only do I know, I also know how to burn glass."
"Ah? You can burn glass!"
Shen Xiaowan's words made Song Yang happy. He didn't expect that Shen Xiaowan understood this.
"Understand a little. The Shen family is a family of merchants. They do whatever they want to make money. This includes valuable glass..."
Shen Xiaowan spoke eloquently, and Song Yang also knew why she knew how to burn glass.
It turns out that glass is a luxury product in Daqian, and the price of some exquisite glass jewelry even exceeds that of gemstones.
Therefore, the process of burning paper glass has always been kept secret.
In order to find out the source of glass, the Shen family also bought some glass themselves.
The texture of the glass is crisp and clear, and it is obviously not gold or jade.
In order to study how glass came from, the old man of the Shen family broke a glass bracelet worth a thousand taels with his own hands, and then threw it into a forging furnace to be burned.
He wanted to see if the glass was burned because he saw something like charcoal fragments inside the glass on the glass jewelry.
This firing really made a difference, and the glass was melted by him.
Not only that, after cooling, it changes into other shapes.
Although the texture is worse.
But the Shen family finally determined that the glass was made from a mineral that burned paper.
So they began to collect various ores to burn glass. As a result, until the natural disaster struck, they did not figure out what kind of ore the glass was extracted from.
Regarding the management and processing of glass, the Shen family is limited to buying defective cheap glass and processing and improving it themselves.
But even so, the Shen family is already leading the way in the glass manufacturing industry.
At least people know that glass is made by burning...
"Haha! Not bad! Very good! It would be great if you can understand a little bit, and it will save me the trouble of having to teach it all over again."
"Xiao Wan! How about you help me burn glass from now on?"
Song Yang laughed and looked at Shen Xiaowan.
"Ah? Burning glass? This civilian girl may not be able to do it." Shen Xiaowan said with a bitter face.
She came here to study business, but she didn't study it, and she was about to become a coolie as soon as she arrived in Jiangzhou.
"Sigh. It's not like I'm asking you to do it yourself. You just need to give instructions to the workers. In a few days when the autumn harvest is no longer busy, I will arrange manpower for you. It's such a happy decision!"
Song Yang is very happy. With a semi-knowledgeable helper to help him, he can relax a lot.
"But... I'm not very good at it, and we don't have glass raw materials now." Shen Xiaowan refused. She didn't want to make any glass.
"Why not? There are plenty of raw materials!" Song Yang laughed.
"Ah? Your Majesty knows the raw materials of glass!"
This time it was Shen Xiaowan's turn to be surprised. The Shen family had not figured out what the raw material of glass was for more than 20 years, but they didn't expect Song Yang to know.
Song Yang was talking about raw materials, not glass, so Shen Xiaowan was sure that Song Yang knew the raw materials for making glass.
"Of course I know. I will teach you in the next few days. Then you will be responsible for watching the workers burn glass."
Song Yang nodded confidently.
"Sister, the prince has said so, just agree to it."
Shen Dan, who was silent for a long time, said softly.
When Song Yang mentioned asking Shen Xiaowan to make glass just now, Shen Dan didn't want his sister to do such rough work.
In the eyes of the Shen family, making glass is just a menial job, just like smelting steel. Isn't working with a stove and ore considered a menial job?
But Song Yang actually said that he knew what the raw material of glass was, and Shen Dan suddenly became uneasy.
He was only twenty-two years old, and the Shen family had been exploring the secrets of glass for twenty years, and even asked King Hongzhou to help find out information from the court.
But there was still no clue, not even the court knew how the glass was made.
Therefore, Shen Dan is eager to know the secret of glass.
The family's pursuit, which has lasted twenty years, finally has an answer.
So he also changed his mind and wanted his sister to learn how to make glass.
In this way, the Shen family's twenty years of hard work have not been in vain.
Of course Shen Xiaowan thought the same way. She had seen her grandfather's persistence since she was a child.
"Your Majesty, Xiaowan is willing to learn and help you make glass." Shen Xiaowan nodded in agreement.
"Hahaha! Okay! Another big event has happened! Let's go home. I might as well tell you how glass is made today." Song Yang laughed.
When I got home, Sister Tong Qian had been waiting for a long time.
The girl already knew when Song Yang came back, and she had already prepared delicious food for him.
But when Song Yang appeared in front of her, Tong Qian became angry and alert as never before.
Song Yang brought a woman home for the first time.
And she is so beautiful and dignified.
She looks like a lady.
"Xiaoqian. This is Miss Shen Xiaowan."
"Xiao Wan, this is Tong Qian."
After introducing the two girls, Song Yang chatted with Shen Xiaowan about glass.
Song Yang explained how glass is made and what raw materials are used.
Shen Xiaowan was so shocked that she could fit a big apple into her mouth.
"Sand? You mean the raw material of glass is sand? The kind of sand on the riverside?"
Shen Dan was also confused and said in shock: "How can this... be sand!"
My family used many kinds of minerals in their experiments, but they never thought about sand.
In fact, the Shen family's test products also contained quartz stone, but there was a problem with their refining method. Quartz stone in blocks was not so easy to burn.
That was the closest they got to the reality of glass, but unfortunately it ended in failure.
That's why they were so shocked when Song Yang suggested that sand was the main material of glass.
"Of course, it's sand. But not all sand can burn glass. Barite, feldspar, and quartz sand are needed, which are relatively common. For example, there is a piece of sand to the east of Jiangzhou Fucheng that is made of quartz. sand."
Song Yang smiled and explained that in addition to ore, there are also additives such as barium carbonate, limestone, soda ash, borax, boric acid, etc.
Only by combining these things can we produce high-quality glass products.
With Song Yang's explanation, the Shen brothers and sisters have opened a new window, and their understanding of glass has also reached a new level.
"Don't worry, Your Majesty! I will swear to keep this secret in my humble position!"
After listening to Song Yang's story, Shen Dan solemnly clasped his fists and said.
"Haha, I believe you when I tell you this. Besides, this thing won't last for many years. Sooner or later it will become popular." Song Yang said with a smile.
Song Yang is imparting knowledge on chemistry in the room to the students, and will also talk about the production of glass in the future.
Song Yang doesn't intend to hold anything back and will tell everyone.
Only when everyone's knowledge improves can society develop faster.
This conversation lasted an hour, and the Shen Dan brothers and sisters still felt incredible when they left.
It is simply unimaginable that that tiny amount of sand can burn glass.
Song Yang said that after the autumn harvest in a few days, he would burn a furnace of glass himself and lead Shen Xiaowan to conduct an experiment.
The Shen Dan brothers and sisters also looked forward to this experiment.
"Your Majesty, Xiaoqian also wants to learn how to burn glass." As soon as Shen Dan and his sister left, Tong Qian walked into Song Yang's arms and said.
"Huh? Why do you want to learn this?" Song Yang asked curiously.
"I just want to learn!" Tong Qian said with a pout.
"Okay, okay! If you want to learn, just learn. Then you and Shen Xiaowan will make glass."
