After on-site testing and measurements, the effective range data of the Tiger Crouching Cannon was finally obtained.
The solid bullet is 350 meters, and the blooming bullet is 60 meters.
Song Yang is still very satisfied with this data.
Of course, there is room for improvement, such as more refined workmanship and more reasonable projectile adjustments.
These will have some impact on range and power.
In the end, Song Yang handed over all these improvements to Song Chengwang. Of course, the specific work was still done by Wang Jinshi and Wang Dabiao. His eldest nephew Song Chengwang was mainly responsible for testing the cannon.
Who made him the commander-in-chief of the Tiger Crouching Artillery Battalion?
The experiment was over, but the inspection team did not leave. They came to Jiangzhou to inspect a lot of things this time.
In the past few days, Fang Zhe has taken them to see the city construction, the construction of the Renaissance Army, as well as the schools, navy and Jiangbei defense system.
In addition, regarding the use of food stamps and other tickets, the inspection team also reached a consensus and decided to implement their own ticket systems when they return home.
Song Yang specifically asked Fang Zhe to tell everyone what needs to be paid attention to in the ticket system. This thing must be guaranteed by corresponding materials, otherwise once the credit collapses, the system will also collapse.
Therefore, the envoys have to stay to learn relevant theoretical knowledge and precautions in using tickets.
On December 15th, the first cement road in Jiangzhou New Town was completed and opened to traffic!
In fact, there is only one section, which is the passage from Xincheng Pier to Xincheng, about four miles in length.
The reason why this section is built first is because the roads in the city are undergoing basic reconstruction and paving.
Moreover, the roads in the city are frequently used, so building the roads in the city first will make it more troublesome for people to travel.
It is better to repair the road outside the city first, and then build the path inside the city after paving the way.
This will make it easier for people in the city to travel during the road construction period.
At the beginning of the hour, the auspicious moment arrived. Song Yang led Jiangzhou officials to hold a grand ribbon-cutting ceremony at the end of the cement road.
Thousands of people gathered to watch.
They all came to witness the completion of the cement road.
The envoys of the inspection team have been conquered by the effectiveness of cement.
In fact, the reception center where they stayed also had a concrete floor, and they already had a certain understanding of cement floors.
But when I saw the straight, hard and spotless cement road, I was still shocked.
"The whole road is paved with cement? How much cement does it take?"
"Would this thing be stronger when used to build a house?"
"The King of Jiangzhou has mastered so many divine objects!"
"Alas! I can't wait as much as the King of Jiangzhou!"
The envoys groped around on the concrete floor for a while, and their admiration for Song Yang rose to a new level.
The ribbon-cutting ceremony for Song Yang's traffic ended with the departure of a carriage of trucks bound for Xincheng Ferry.
The people burst into cheers.
We are full of expectations for the construction of cement pavement in the city.
…
Cement pavement construction has begun in the city, and the inspection team is still studying and conducting research in Jiangzhou.
Song Yang is still testing the truth through practice.
Song Yang has truth, and there is a lot of it.
For example, the formula of glass.
But the practical results are not ideal.
The day after the cement road was opened to traffic, Shen Xiaowan found Song Yang and reminded Song Yang that it was time to build glass.
Song Yang understood it, so he immediately had the kiln built.
Yes, he had indeed forgotten that there had been a lot of things going on recently, and the glass-burning matter had been delayed.
The kiln was completed in one day, and we took Tong Qian and Shen Xiaowan to the kiln test site.
The sand chosen is high-quality quartz sand. The quartz sand by the lake in the east is of very good quality and can be used as a test sample.
The glass materials Song Yang can find now are mainly quartz sand and limestone.
Some potash is also produced by spraying plant ash with water. Of course, potash is always a little less interesting than soda ash.
But at this stage, we can only get this kind of potassium alkali for use.
Fortunately, Song Yang's requirements were not high. He could only make glassware, and then he could start cultivating penicillin.
The record about ordinary glass in the Encyclopedia is:
na2co3sio2=na2sio3co2↑(condition: high temperature)
caco3sio2=casio3co2↑(condition: high temperature)
The final common glass composition obtained is: a melt of na2sio3, casio3, and sio2.
Once the materials are available, the preparation experiment officially begins.
Because he had no practical experience, Song Yang threw all the materials into the kiln.
Shen Xiaowan frowned as he looked at it. He felt that there might be something wrong with throwing the materials in so hastily.
However, Song Yang said that he could make glass, and Shen Xiaowan could only respond by observing and learning.
As the furnace temperature increases, the material gradually melts.
It soon turned into red mortar, and as the mortar continued to be fired, it became glass mud.
Through the kiln mouth, Shen Xiaowan also saw the red glass mud.
I couldn't help but exclaimed: "It's really done!"
Back then, he had seen his grandfather burning glass, and this is what the glass looked like in the kiln.
"Is this thing just glass? It doesn't look like it?" Tong Qian also looked in curiously.
She came from the palace, so of course she had seen glass products, but this red-hot glass was completely different from anything she had ever seen.
"It should turn into glass after it cools down." Shen Xiaowan explained.
Song Yang asked someone to put away the kiln flames and use an iron rod to pick out the glass mud.
Then place it on the iron plate prepared in advance.
A large ball of red glass mud immediately raised the surrounding temperature.
This time Song Yang was worried again. He didn't prepare an iron roller to press the glass, but the iron rod was too light.
He could only pick out some of the glass mud and flatten it with an iron rod.
This means that Song Yang's physique is extraordinary, otherwise he would not be able to press the glass clay with a thin iron rod.
As Song Yang pressed it, the glass mud became thinner and thinner, and the color became lighter and lighter.
After a while, the color of the glass mud faded, revealing a variety of colors.
That's right, it's colorful...
Yellow, red, blue, green, white...
The texture is clear and intricate.
"Wow! This glass is very beautiful!" Tong Qian exclaimed.
Shen Xiaowan was also interested, thinking that the things Song Yang baked were very beautiful, and at least they could be sold at a high price as handicrafts.
This kind of glass is actually considered a success for a businessman like Shen Xiaowan.
But for Song Yang, he wanted to use glass as a vessel, and this glass obviously did not meet the requirements.
Putting aside the color issue, the bubbles and various impurities in the glass alone tell you that this thing is definitely not strong.
Sure enough, after the glass cooled, Song Yang picked up the glass and applied a little force, and the glass broke into several pieces.
"These are good pieces. It would be great to polish them and make them into jewelry!"
"Yes, yes! These pieces are not bad. They will look great when rounded and worn as a bead necklace!"
"Yes, yes! This one looks good too!"
Tong Qian and Shen Xiaowan's focus was on the broken glass fragments.
Looking at Song Yang next to him, he had a black line on his forehead and was speechless.
I don’t want two girls to be involved in the work of burning glass anymore…
