The role of lime is not only used to build a house, but also the same as pure alkali. It is one of the basic industrial raw materials. The application scope is very wide.
It can even be used as a medicine.
Therefore, the area of the Xihewan lime plant is very large, and there are three lime kiln.
In the northwest corner of the limestone factory, there is a small workshop, and there are not many workers, there are only six.
However, this small workshop is the most tight defensive place in the Changshegou Industrial Zone.
Six workers are also selected by Xiaoyu Jing, who can absolutely trust.
Here is Jinfeng's glass laboratory, which is built in a stove that is specifically used to burn glass.
After Jin Feng came in, the two workers looked at the ground with excitement.
There are several green crystals on the ground, which is about the same as that of the big fist. The small ones are only as large as walnuts.
"Sir, look, we burned out!"
A worker pointed at the crystal block and said excitedly: "This thing is too beautiful!"
The crystal block is glass, but the workers couldn't get it in the mold, and it became a ball to fall on the ground.
And because there are many impurities and the color is not pure, there is a very heavy green color, and the transparency is also very low.
Jin Feng glanced at the stove and found that there were still a lot of glass liquid. He took a hollow iron tube that had been prepared for a long time.
"stop!"
Jin Feng knew that the Princess Nine was chased, so she had to put down the iron pipe, ran to the door, and led the nine princesses and Qing Mulan.
But except Qin'er and Amei, the other guards were blocked by Jin Feng.
"Such a large piece of Liu Li Shuiyu!"
As soon as the Princess Nine came in, she saw the glass regiment condensed into a group on the ground.
"Do you know this thing?" Jin Feng frowned.
In the history of previous lives, the glass was originally made by the ancient Egyptians, but I do n’t know why because of the reason, it did not spread.
It was the Phoenicians who carried forward the glass. They accidentally made the glass and then made a lot of money.
For a long time, the glass is a very expensive luxury product, known as water jade.
Because of its rarity, the value of glass in ancient times is far beyond the gold and most natural gems.
There are historical records that during the Tang Dynasty, there were several glass beads in Hu Shang and purchased a expensive house in the prosperous Changan.
In Jinfeng's plan, glass is a very important product.
If the operation is properly operated, the income brings is not weaker than soap and black knife.
The reason why there is such a great confidence is because Jin Feng sent someone to investigate. Dakang has no glass at present.
But Princess Nine recognized it at a glance, and it was obviously seen.
"Knowing, the messenger of the country in the past few years came to Dakang, and there were a few pieces of Liushuishuishu in the gift to the father. The father emperor liked it.
"Princess Nine answered.
"What are the water and jade products they bring?"
"Without these big, the biggest one is only as big as the pigeon eggs, and the color is very turbid. There are not these beautiful looks. There are still many holes in it, but it must be slightly rounded.
"Princess Nine answered.
When he heard Princess Jiu said that, Jin Feng was relieved.
The color is turbid and bubbles, indicating that the technology of making glass for the other party is still in a very backward stage.
In fact, the development of glass has stalled for a long time. For hundreds of years, everyone thinks that the glass is originally green, and there will be no other colors.
It was later discovered that the reason why the glass was green was because the raw materials contained a small amount of iron.
If you change the raw materials, you can make glass of other colors.
As for the processing method, it is also very simple. Cooling the glass liquid into large and small beads can be worth a lot of money. There is no need to further process it.
The glass has been used as a gem for thousands of years, and then there is a large piece of glass.
And Jin Feng not only knows how to make the glass color, but also how to make exquisite glassware and large pieces of glass.
However, Jin Feng did not relax his vigilance because of this.
The development of glass in previous lives was slow because when the manufacturing technology was transmitted to the Italians, the Italians carried out the blockbuster and detained the glass on a small island. They could not leave for life.
This move prevented the technical leakage, and there would be no competitors.
No one competes, there is no motivation for progress.
Later, the technology spread, and quickly developed rapidly, and various glass products emerged endlessly.
Glass also quickly changed from luxury goods to ordinary goods.
Jin Feng now has the most advanced manufacturing technology, and naturally you must make a sum.
Knowing and knowing that he could fight all the battle, Jin Feng inquired: "Did the messenger of the country say where they got from?"
"Said," Princess Nine replied, "It said it was robbed from a group of red -haired pirates.
"
"Red Mao Pirates?" Jin Feng narrowed slightly.
There are few people with red hair in Asia, and the biggest maybe the biggest of the red -haired pirate is white people from Europe.
Before Jin Feng passed through, the host was just a scholar in the mountain. He had never seen any world.
Dawang's various industries are very backward, so Jin Feng feels that this world is still in a very backward era.
But now that Europeans have come to the country, at least it shows that European development should be better than Dakang, at least the shipbuilding industry is definitely better than Dakang.
I don't know if Europeans have found the Americas.
Thinking about things in his heart, Jin Feng didn't stop in his hand. He reached into the stove with the iron pipe.
The material to make glass is sand. After high temperature melting, the sand becomes a viscous liquid similar to the sparse sugar.
This is the glass fluid.
I picked a small group with an iron pipe, but the result did not wait for Jin Feng to blow, and the glass liquid fell to the ground.
Jin Feng was not discouraged, and stretched the iron pipe in and picked up again.
With the last lesson, this time Jin Feng put the glass liquid at the entrance of the stove for a while, and it was cooled a little before taking it out.
This time the glass fluid did not drop, Jin Feng quickly put his mouth to the other end of the iron pipe to blow air.
The ductility of the glass liquid is very high, similar to the balloon. Under normal circumstances, this group will not break as big as basketball.
But I didn't know why because of the reason, Jin Feng had blowing it twice, and the glass fluid suddenly exploded.
Fortunately, Jin Feng wore a hood to protect it, but a worker was too close, a small piece collapsed on the back, and was hotly jumped up.
Jin Feng didn't give up, threw off the failure glass fluid, and picked another group.
The result still failed.
Once, twice ...
After more than a dozen consecutive experiments, Jin Feng's cheeks were exhausted, but it was not successful at one time.
Either dripping directly, or if it is over -cooling, it can't be blowing at all, or it is blown up when it blows.
At this time, there were cool and molding glass on the ground. The workers were far away from Jin Feng, for fear of being burned again.
