"Huh? This is?" Zhu Qinfeng's ship had not yet docked, but this guy sent someone to send a small gift to Zhengliang in advance. When Zhengliang returned to Anyue City and saw such a small gift, he was surprised.

This turned out to be a small glass ball.

When he saw this small glass ball, Zhengliang couldn't help but secretly slapped himself. He had always forgotten about glass. This is a good thing to make money. Glass is not fully popular in the East, so glass has always been regarded as a luxury, especially in Ming Dynasty. Glass with a slightly larger area will be purchased by officials, businessmen and wealthy gentry. Moreover, Zhengliang can also sell glass to local Japanese and even North Korea and other places.

The method of making glass is not complicated. You only need quartz sand, soda ash, feldspar and limestone, which can be made by melting at high temperatures and then crushing them flat. Recently, in order to speed up the production of bricks and prepare for the construction of ceramic workshops, the Luo family happened to introduce the well-developed porcelain kiln technology of the Ming Dynasty, which can reach the corresponding temperature. The details of it. As long as the craftsmen carefully study it, they can actually be invented and created.

There are some masons in the territory who have made porcelain in the Ming Dynasty before. They are very experienced in mastering the temperature of porcelain kilns. It is not difficult for this porcelain kiln to reach the temperature of melted glass.

He did it as soon as he said it. Zhengliang immediately found relevant craftsmen and explained to them the specific method of making glass. Because many of these craftsmen have heard of glass for the first time, Zhengliang had to explain the specific method of using each process, every step, and even every piece of utensil. He even needed to give guidance on the spot.

In the following days, Zhengliang stayed with these craftsmen. In order to ensure the smooth manufacturing of glass, Zhengliang also organized these craftsmen to practice several times, until their gestures were very skilled and their cooperation with each other was tacit. Only in the end did they start to make real manufacturing.

Fifteen days later, when all the materials were ready, a porcelain kiln that was temporarily built to produce glass was finally built in the workshop canyon.

When Zhengliang personally announced the start, a raging fire immediately ignited in the porcelain kiln. The craftsmen put the raw materials into the container one by one according to Zhengliang's previous training order. After continuous burning and forging, the glass solution of the first furnace was finally released.

On the open space outside the porcelain kiln were placed. After the glass solution came out of the kiln, several big men shouted horns and poured the hot glass liquid in the furnace onto the iron table. Then several craftsmen dragged thick cast iron round sticks and grinded them back and forth. Soon after the glass was flattened, they formed a large piece of the same as the tabletop, and a flat glass was formed.

Of course, although the flattened glass is very large, the side length is exactly one meter, but it is not smooth. It still needs to be polished. At this time, several craftsmen came over and placed the large flat glass on a table covered with thick felt and sprinkled a layer of fine sand. Then put another flat glass plate, and by pushing and pulling the glass on it, the fine sand smoothed the two pieces of glass.

However, this work seems simple, but it requires five or six craftsmen to work for more than one day. And this is not enough. The surface of the glass treated in this way has countless patterns left by fine sand, which needs to be further polished. The craftsmen use an extremely fine ore powder and water to rub back and forth with small wooden boards wrapped with wool felt for hundreds of thousands of times. Because it is purely handmade, the output cannot be very large.

What’s even more depressing is that the first piece of glass made in the end is really bad. It can be said that from the outside, it is just a strange product and has nothing to do with the appearance of glass in consciousness.

Zhengliang had already expected such a result. Zhengliang was not in a hurry anyway, so he just let these craftsmen study it slowly.

After putting down the glass, Zhengliang began to be busy with another thing. That is the manufacturing problem of Climate Eye (that is, telescope).

The idea of ​​making clairvoyance is caused by the creation of glass. The application of clairvoyance in land and military and maritime navigation is really important. Moreover, clairvoyance is even simpler than glass.

The main raw material for making clairvoyance is lenses. Lenses can be made of crystal stone, quartz, topaz, amethyst mills and other things. Ready-made lenses can also be purchased in the West and the Ming Dynasty.

Of course, this is just a trial product of the Roche family. In my memory, the first Western clairvoy (teleoscope) was invented by Hanslippershey, the owner of an optician in a Dutch town in the early 17th century. In order to check the quality of the grinded lens, he arranged a convex lens and a concave lens in a line. Looking through the lens, he found that the church tower spire in the distance seemed to be getting bigger and closer, so he accidentally discovered the secret of the telescope. In 1608, he applied for a patent for the telescope he made and followed the requirements of the authorities, and built a binocular. It is said that dozens of glasses in the town claimed to have invented the telescope, but Lippey was generally believed to be the inventor of the telescope.

The Ming Dynasty only recorded the Climate Eye (teleoscope) during the revelation of the Ming Dynasty (1605-1627). So the Luo family is now really crossing the river by feeling the stones, as the first family to study Climate Eye production.

Whether it is glass or clairvoyance, these half-baked craftsmen under the Luo family need to study it slowly, so Zhengliang also began to focus on other things in the territory.

First of all, the ones who came into Masara's eyewitness were the battle report about the Ouchi Yoshitaka Army in Izumo. It was already early April. According to the latest information, the Ouchi coalition finally suffered a defeat.

It was November last year when Masayoro retreated from the battlefield to the qianhou and Aoi army finally slowly attacked the outskirts of Tomota Castle in Yueshan. Yoshitaka Ouchi was stationed at Sandaowu Peak, but the Dauchi army, which had lost its spirit, made extremely slow progress. It was not until February this year that Yoshitaka took another step forward and moved its formation to the slightly forward Kyoraki Mountain. In fact, at this moment, the defeat of the Dauchi Army was decided. Not only did Haruki not move the New Palace Party in his hands, but he also kept drawing new forces from Boqi and Bei.

, ready to launch a counterattack. Sure enough, the Ouchi Army suffered repeated setbacks after that: Maori Mori, Naito Hirohiro attacked Sugatani, and was defeated by the Nishu Yukikiya army; Hiroshige Hiroshi, Hiroshita, and Tokura Temple, were defeated by the Nishu Kuroshi. In April, Maori Mori led the eldest son of the Chu Formation, Mori Takamoto attacked Shinoyaguchi, and left a shadow on Takamoto's first formation and was defeated by the New Palace Party. Takamoto escaped under the desperate guards of his retainers, and when he came back, he sighed, "It's a life-long Shura Field."

After receiving the latest news that the Danai Lianjun was frustrated again, Masara knew that it was not long before Onai Yoshitaka's defeat in Izumo and many things had to be planned in advance. So Masara quickly issued several targeted orders. After the order was issued, Masarara thought about it again and confirmed that there were no omissions, Masarara breathed a sigh of relief.

Then Zhengliang finally saw the news that the few people he invited also came to the Luo family. So a meeting about the future development of the Luo family was held in Anyuecheng.
Chapter completed!
