So no one is urging them these days, and although many people are anxious to go to sea, everyone knows in their hearts that this is making glass, not the kind of labor-intensive bricks and cement.

Even if it is a sugar factory made a while ago, in terms of technical content, it is a big difference from this project, as for the expensive equipment, not to mention, the glass factory project is related to the strategic layout of the entire crossing group to go to sea trade, and each participant feels that he has a great responsibility on his shoulders.

And the onlookers were also infected, and during this time, everyone had a feeling of walking on thin ice.

From mid-April to late May, all the staff of the chemical team and the mechanical group, plus Zhou Ruiyuechu and a few people who came to support them in shifts, went back and forth between the karst cave and the glass factory at two o'clock every day, studying the equipment and discussing the technology, and they even had no intention of watching the lively dam construction site, because most of them had to stay up until after 12 o'clock in the evening every day.

In late May, the equipment installation and commissioning was finally coming to an end, and finally, Mr. Zhao, Mr. Wang Gongluo, Boss Luo and other bigwigs decided to start trial production on the 22nd.

At half past nine o'clock in the morning, the trial production of the glass factory finally began, as before, whenever a new project was put into operation, all the traversers had to go to the site to visit (surround) the scene, this time not only all the traversers were present, even the young children came.

However, the children's focus is not on the factory, but on the road, and this is the second time in their lives that the children are traveling by train, and the children are either laughing or screaming in the wagons.

Fortunately, because of their previous experience, the children did not cry or be so frightened that they curled up and hid in the corner without saying a word.

This is completely different from the situation a few months ago, when the children first arrived at the Red Wharf, they were first distempered by the ruthless washing of the women, and then they were taken on the train.

At this time, everyone found that the members of the mechanical group of the chemical group were all in a circle, their faces were a little haggard, and they looked like they were sleep-deprived.

But we can also understand, people who engage in technology will be like this when they encounter pressure, speaking of work, everyone is hard, but mental work is different from doing physical work, the latter is tired, can eat and sleep, and can recover in a few days, the former is tired, can't sleep and can't eat, and if you don't solve the problem, it is impossible to recover both physically and mentally.

At nine o'clock in the afternoon, after a tense inspection, after more than two years of crossing, the most important trial production so far finally began in front of all the traversers.

The tension even spread to the onlookers, who for a while quietly watched as they ran around in front of everyone with a serious face, and at this time the crowd was so rare that no one even laughed loudly, for fear of disturbing the work of others.

For glass production, the quartz sand on this island is one of the few high-purity glass raw materials in the world, and the sand material is almost not subject to mineral processing, and a small amount of borax is produced in the nearby wetlands, where the halide borax is not as high-quality as that produced on the nearby islands, but it can also be used, so it has been prepared for a long time.

As for limestone, that's even more readily available.

Therefore, the whole batching process is relatively simple, just for the convenience of melting, there are some requirements for the size of the particles, so these raw materials are carefully mixed and poured into the furnace after only a few sieves.

As the coal dust mixed with gutter oil was ignited by the high-pressure gas stove, the temperature in the flame furnace rose rapidly, at this time, Mr. Zhao and the others were a little nervous, their eyes were glued to the thermometer, after all, the flame furnace was Anna's "innovative" design, and they didn't know how much the final temperature of this furnace could reach.

Finally, Mr. Zhao and a group of people showed a look of relief on their sweaty faces, Qiao Xiaomu and Gui Xianning next to them also seemed to breathe a sigh of relief, and Boss Luo, who was standing not far away, turned around and said to the onlookers who were looking bewildered nearby:

"Eight hundred and ninety degrees."

However, the reaction of the onlookers was: "......"

But judging from Boss Luo's relieved expression, the bewildered faces of the onlookers did not affect Boss Luo's mood at all, and at this time, Wang Xue stood far away in the women's pile and whispered to the female companions next to him:

"The temperature is a little higher than expected, which is a crucial step, and it is related to the temperature that the molten glass in the subsequent melting furnace can reach, thanks to Anna, the performance and structure of this special flame furnace that he provided us with are very good......

At the same time, Gui Xianning, who was operating on the side of the flame stove, was also introducing the situation to the people around him, saying that because this process was different from the traditional process, it was different from what was written in the textbook, so everyone was not sure about it, and it was normal to be a little nervous.

Everyone nodded frequently after listening, and finally someone began to respond with some words of encouragement that were not salty or light.

So in the mutual communication of everyone, time gradually passed, at this time Mr. Zhao through a very small observation hole, saw that a small amount of 100 kilograms of quartz sand in the flame furnace began to appear from the top, some have gradually sunk, with the expansion of the melting range, Mr. Zhao decisively opened the bottom of the furnace, so that the semi-molten raw materials flow into the electric melting furnace below.

As Boss Luo calmly closed the electric switch, the electric lights of the entire glass factory flickered, which indicated that the big tiger that ate electricity, the melting furnace, began to work.

The melting furnace heated up rapidly, and at this time, Mr. Zhao and others took turns to observe the thermocouples, and the buzzing sound inside the furnace lasted for half an hour, and Mr. Zhao shouted excitedly:

"1100 degrees!"

"Great......"

The members of the chemical team and the mechanical team gathered around the fireside couldn't help but applaud and cheer.

"This is a momentous moment of decisive significance!"

"There's hope......

At this time, the science and engineering men around Mr. Zhao began to discuss enthusiastically, and judging from their expressions, they were obviously relieved from some kind of burden, and several bigwigs almost all exhaled in unison.

Although the surrounding melon-eating crowd still looked confused, they were obviously also infected by some emotions, and everyone's faces were less serious, accompanied by a few baby cries not far away, and the atmosphere of the entire production site was suddenly much more relaxed.

Because the purity of the raw material is very high, if this temperature is reached after melting, then the transparency of the molten glass after cooling should be guaranteed.

An hour later, Mr. Zhao excitedly announced to the people around him that the temperature inside the furnace had reached a record 1,300 degrees! Then Lang Sheng told the onlookers that the furnace will be opened soon!

In a few moments, the furnace door was hooked open, and as the surrounding people watched excitedly and in amazement, lava-like, golden-yellow glass slowly flowed out of the furnace.

Zhou Rui and Yue Chu served as temporary furnace operators, and they saw that the two of them cooperated with each other, one with pliers and one with latte scissors, and when they went up to cut and connect, they quickly introduced a ball of molten liquid into the steel die prepared in advance.

While the temperature was still ready to shape, another mold was quickly fastened, and then the assistant next to him took it away with large iron pliers and put it into a large iron cabinet like an incubator.

There is an electric annealing furnace where the glass is gradually cooled and the thermal stress is relieved.

Zhou Rui and Yue Chu took a few partners to operate continuously, until the annealing furnace was full of steel film, and the raw materials in the melting furnace were basically exhausted.

All that's left is a nervous wait.
