Traveling through the Prosperous Pastoral of Peasant Girls

Chapter 117 Telescope

After they arrived, all the people and craftsmen were divided into two parts, and a large house could be demolished once they entered and left the port. These parts were numbered by category, and the craftsmen assembled them step by step to form a complete house. up.It took only four days for the two houses to be relocated from Shark Island and assembled. The crew joked privately, "The young master has demolished the pirate's east wall and repaired his own west wall."

After relocating the twelve buildings, a large number of stones were prepared for the construction of the furnace when the foreign master arrived.At the same time, raw materials such as high-quality coal and soda ash were also shipped in a steady stream.

At the end of April, 16 foreign glass-making masters and their family members arrived at Liangshan Port. After resting in the inn for five days, Lu Run asked them to recommend one or two most experienced people to go to Yazui Port to guide the construction of the furnace.

When they were in the Raksha Kingdom, they only earned two gold coins a month for hard work, which was more than double the wages of ordinary workers.After the pirate dug them over, he promised to give each of them three gold coins a month.Zhang Sheng Luo Luo dug them over again and promised to give them four gold coins a month.In a letter to Lu Run, Jin Yan said: "If they do a good job and the glass they produce sells well, their wages will be raised to five gold coins a month in the future."

Everyone likes money, no matter if it is Chinese or foreigners, and if you have money, you will have the motivation to work. With Jin Yang sitting here, the progress of the project has been advanced a lot.

Jin Yan and two foreign masters studied their previous glass making technology. They used to use a crucible kiln. Eight crucibles can be heated together in the kiln. The crucibles are filled with quartz sand, limestone, feldspar, soda ash and boric acid. , After heating, it is poured out and flattened to become flat glass. In order to prevent the glass product from collapsing and shattering during the cooling process, such glass needs to be annealed.

This let Jin Yan know the reason why the glass is limited to a small area. They only know this method, not the molten pool method.The melting pool method is to put the raw material of the glass in a heating pool to melt, which can reach several square meters. The amount of glass solution melted in the pool is large. When the finished glass is produced, the vertical leading method and the flat pulling method are used. The best Glass is produced by the float process.From this, Jin Yan told them about the production of a melting pool kiln and the production method of float glass.

They are all old-fashioned people, and they don't agree with the method proposed by Jin Li at all, and insist on using the crucible method they are used to.Seeing that he couldn't agree with them, Jin Yan agreed with them to build a standard crucible kiln, and he and Liu Maoxiaosi designed a melting pool kiln for craftsmen to construct.

The molten pool furnace also reformed the blast device. In the past, the craftsmen used the manual blast device, that is, the blast nozzle made of animal skin, to heat the coal blast.Jin Yan reformed this device and made a hand-operated blower. When it was shaken, the wind was strong and even at a constant speed, which made Master Yang praise him.

While building the two melting furnaces, Jin Yan told Lu Run to organize raw materials such as soda ash and feldspar boric acid, and the blowers were also produced in Liangshan Port.In addition, it organizes metal tin used in steel and float glass.Steel is used to make tools. There are tools such as iron chains, iron hooks and iron pickles used in coal-burning stoves, and there are even more used in making glass. There are as many as ten types.

The blacksmith furnace also built one. After the craftsmen finished the work, there were six crew members who broke raw materials and a few logistics personnel, and the cargo ship transported them away in the dark, which went directly to the Jinfu Wharf in the capital.When the ship came back, it brought all the foreign masters and their families, and brought a lot of daily necessities. Lu Run used the express boat as a transportation ship, and went back and forth from Liangshan Port to Yazui Port every other day. If it is sunny, I have to go to Shark Island for a visit.Because there are three people left behind on Shark Island, who stay behind to guard against pirates, while mining quartz stone and picking the quartz sand on the beach.

After these foreign masters rested in Yazui Harbor for two days and got familiar with the environment, they started to light the fire.

Jin Yanliu Mao Xiaosi watched their glass making process for two days. There are many similarities between making flat glass and glazed crafts. The biggest difference lies in the use of raw materials, because thin glass is basically white, and thick glass bricks are a bit quiet. green.

Colored glass is different, you can manually intervene in its color, the raw material for making colored glaze is because of the colored glaze mother added by colored glaze stone, the ratio is only approximate, and it depends entirely on the mastery and calculation of the craftsman's mind.

Their foreign masters worked for three days and got a total of 340 sheets of flat glass. Although there is not much synthetic silver, this is something that is urgently needed. Regardless of the size of each sheet, it can be used on windows.Restaurants and shopping malls, as well as windows for those supporting facilities, are in huge demand.

The quality of the glass is acceptable for Jin Yan. If it is made into a telescope, it only needs to be strict with the materials used for the glass.However, glass of the same thickness has to be cut and ground, and it would be too labor-intensive to grind it by hand.He plans to pour high-quality molten glass into a mold made of silver for preliminary shaping, and then grind it to save labor and effort.

He first made the clay into the general shape of a concave lens and a convex lens, then made a wooden transmission device driven by water flow, and then made a telescopic tube for a monocular.The transmission device is miniaturized. When the time comes, the blacksmith in Liangshan Port will scale it up. Adding the acceleration device will make it a mill.When the telescopic barrel of the telescope is made of silver by the silversmith, it will be strong and durable.

After squatting in Liangshan Port for five days, he finally prepared all these things.If the telescope is successfully produced, it will be sold at a higher price than quicksand paintings, because the army and ocean-going ships are the first choice for using this thing, no matter which country will spend a lot of money to buy it.

This time, Liu Mao and Xiaosi applied the technique of making glass to the process of making lenses. This is the first time that such a mold is used to make a blank.They poured a crucible of high-quality glass solution on the mold, pressed it into shape, and then annealed it.

After suppressing the convex lens and the concave lens for 20 yuan each, and then grinding and polishing with a water flow mill, the three of them worked hard all day to grind out two pieces, but the effect was not ideal after installing the telescope tube, the reason is that they were ground If the lens is irregular, the resulting image will be blurred and distorted.Jin Li knew that this was because the three of them were not familiar with the grinding process. If the manufactured telescope reached the level of ordinary telescopes, it would take time to explore.

Although the lenses were temporarily unqualified, Jin Li knew that they were inexperienced in making them, so he encouraged them instead.Also took out the convex lens lens, and used the lens to gather sunlight to ignite the firewood.The convex lens actually has such a magical effect, Liu Mao Xiaosi immediately followed suit.These days, the use of fire is still using the scythe and velvet as the kindling, and this is the first time I have seen such a convenient method of making fire.

It wasn't until ten days later that the molded lenses were pressed and hundreds of lenses were processed. Then under Jin Li's careful selection, a telescope with a multiple of eight was assembled, and the imaging effect of the viewed scenery was almost qualified.With the proficiency of several people's skills, the quality of the telescope gradually improved greatly, and later reached the output of one qualified product in two days.The important thing about these binoculars is not the quantity, it is the same as quicksand paintings, and they cannot be dumped overseas in large quantities, which will make people think that the binoculars are high-end goods.

With the current technological level, it can only produce single-lens telescopes. If it is to produce binoculars, it is not a difficult task after research, but the current situation is that it is temporarily unnecessary.In order to make a long-term plan, it is appropriate to use binoculars as a technical reserve.

Now, the importance of Yazui Port is on the agenda. First of all, it is to prevent pirates or people who want to dig out their nests. Jin Yan planned to command several crew members to build two observation points on the cliff at the exit of Yazui Port. Secret sentry, took the wisteria again to disguise it, if the ship passed outside the port, if you didn't pay attention, you wouldn't be able to find the high sentry position at all.

You can't see the sentry posts near the sea, and you can't tell them apart when you see them on the distant sea. In the shack, you can clearly see the extreme distances on both sides of Yazui Harbor. There are four shifts a day, and they are always under surveillance. On the surface of the sea outside Yazui Port, if there is any disturbance, the people on the sentry post can immediately let all the crew members block the port.

Jin Yan plans to call in a few more people to strengthen the defense of Yazui Port, and make sure that no strange ships are allowed to enter the port.They just made a plan, but they didn't have time to implement it. They just put a sentry there.

This morning, the fast boat arrived at Yazui Port, and Liu Tao and Wu'er came with the boat. Seeing that Jin Yan and Liu Mao Xiaosi hadn't gone back for so long, she came to have a look because she was worried.In fact, Jin Li also misses her very much, so Liu Mao grabs Liu Tao's hand first, and asks Liu Tao, but Jin Yang can't get in the way.

A crew member named Da Lei served as the captain of the clipper. When unloading the fresh meat and vegetables, he asked Jin Li if there was nothing he could do, so he drove the boat to Shark Island, and then returned directly to Liang from Shark Island. mountain port.

After they left, Liu Tao took charge of the kitchen and cooked a few dishes to reward them. After the meal, she inspected the telescope they made like a quality inspector.

When the evening approached, Da Lei and his clippers came back again.Regarding the return and return of Da Lei and the others that the sentry post said, Jin Yan also became puzzled, and climbed to the sentry post to watch. A fast boat was approaching from the direction of Shark Island. Judging by the speed, it seemed that someone was chasing behind, but he didn't see it. until another ship appeared behind it.
