The first thing to do in refining glass is high temperature, followed by raw materials and processes.

In the process of sugar extraction, Wu Nuandong has mastered the knack of high temperature, charcoal and a hearth with a nozzle are indispensable, with the development of science and technology at this time, don't expect any high-end technology, she alone can not meet the requirements. The so-called ancient law is the most time-saving and labor-saving to conform to the times.

It is very important to prevent heatstroke and dehydration and prevent scalding in a high temperature environment, Wu Nuandong repeatedly told his subordinates to pay attention to safety, and must arrange good manpower during the furnace period, a group of four, half a quarter of an hour for a round, two by two rest. One group can only take care of the hearth for two hours a day, and the shift system is implemented.

Wu Nuandong should first equip the raw materials in proportion, and then heat them at high temperature after they are put into the mixing barrel and stirred evenly.

Melting is a very complex physical and chemical reaction process, which is carried out in the furnace. There are two main types of melting kilns: one is the crucible kiln, where the frit is contained inside the crucible and heated outside the crucible. It doesn't meet Wu Nuandong's requirements, so he can only abandon it. The other is the pool kiln, where the frit is melted in the kiln pool, and the open flame is heated on the upper part of the glass liquid surface, and the temperature can reach more than 1,300 degrees.

"Girl, get out! It's so hot!" Wu Daxu was sweating profusely, his face was red, and there were seven people behind him, all of whom persuaded Wu Nuandong.

They were sturdy and adults, and they couldn't stay around the kiln for long, and even if they looked through the small hole that showed a little space, they could be smoked and roasted. In just a moment, the hairs on his body were roasted, which showed the power of the pond kiln.

"Don't get in the way, your martial arts are not as good as mine, go out!" Wu Nuandong waved his hand calmly, his forehead was slightly sweaty due to the burning heat, and his little face was pink, but he still refused to leave.

Wu Daxu and the others were secretly anxious, and naturally they didn't want to turn their backs on their masters and leave alone. After a while, the vest was wet and dry, dry and wet, and the whole person was like dehydration, with chapped lips and red eyes.

She heard the heavier breathing behind her, turned her head and frowned slightly to look at a few people disapprovingly, "Look at me, it's no different until now, look at you again!" If you fall, whoever will continue to make zuò glass for me, go out! If you really don't feel at ease, you can come in and have a look after a while. ”

A few people couldn't hold on, so in order not to cause trouble to their masters, they could only help each other and walked out. As soon as I go outside, the weather that usually feels hot and humid becomes fresh and cool, and I really know how to cherish the preciousness in front of me!

Wu Nuandong saw with her own eyes that the raw materials were gradually fossilized into water, this process is not seen by ordinary people, it is too hot, only she used her internal force and the aura in the jade mansion to resist the temperature that can roast people, so she persevered. When there were no more impurities in the molten glass, she used an hourglass to calculate the use, and after the temperature near the kiln slowly dropped, she called back her subordinates, placed the molten glass on the tin plate, and cooled it with ice water.

It seems simple, but it is actually very troublesome to operate. The molding step must be carried out within a certain temperature range. It is a cooling process that first transforms the glass from a viscous liquid to a plastic state and then to a brittle solid.

After that, it is time to determine the shape of the glass.

This step is still a bit far away for Wu Nuandong, and it took more than a month just to confirm the ingredient ratio and temperature control. For more than a month, she has been soaking in the pond kiln every day, which really makes the old man of the martial family feel painful, and several adults and two brothers at home will come to replace her as soon as they are free. There is nothing else to say, but no one can replace it, because to monitor the process and time of liquefaction at all times, as well as the problems that will arise, she must and only she can record and change it herself. Therefore, even if the adults are distressed, it will not help, so they can only take turns to come to Siping Village to accompany her.

Glass molding mainly relies on manual blowing, drawing, pressing and free forming methods. For example, free forming is the method used by today's glass masters. Wu Nuandong is not needed, the first three items are enough.

These also require effort, just blowing, it wastes a lot of liquid glass, Wu Nuandong hasn't said much! Wu Da Xu, who was in charge of blowing, first clenched his fists, and then gave his stupid mouth a fist, "It's all up to me, so much has been ruined!" ”

As soon as he said it, the other two subordinates didn't dare to get started lightly, no one was sure, and when they thought that these molten glass were smelted by their own girl's hard work, they suddenly looked at the molten glass with an expression like looking at a treasure, and they almost held it in the palm of their hands.

Wu Nuandong rubbed her temples, and she couldn't bear the continuous high-temperature work.

"Get it! I've summarized the secrets of high-temperature smelting, and I'll leave it to you completely later. ”

Hearing this, everyone gradually had some music in their hearts, and they really let it go.

Wu Nuandong took out the Xibo, cut it according to the size of the glass block, and pasted it on the glass surface, then poured mercury to dissolve the tin, and waited until the tin foil turned into a viscous silvery-white liquid that was tightly attached to the glass, and it became a mirror.

Wu Nuandong held the first mirror she made, and took the opportunity to melt a piece of silver to make the lace and handle of the mirror, even if it was slightly rough, it really reflected her reflection, and they succeeded!

When the horn of success sounded in every corner of the factory, the people were indulgent and shouted, and the old man who was waiting outside hurriedly rushed in, picked up Wu Nuandong to check her safety first, and saw that she was beaming and in good spirits, so he shifted his attention to the mirror.

The same woman, the two aunts and sister-in-law Zhou took the first step to discover the difference and importance of the mirror, and they were reluctant to put it down when they picked it up.

Fortunately, Wu Nuandong had the foresight to make four pieces, otherwise it would be really difficult to divide.

"Nuan Nuan, this is good, this is a woman can't do without it!" The aunt's eyes flashed, as if she had fallen into the eyes of money. It feels like Wu Xingzhou is like her son rather than the second aunt's. When the two of them mentioned making money, they had one expression.

Wu Nuandong smiled with relief, just the mirror, she used three and a half months, which lasted a long time, but she recorded the whole process of making glass, and it was not so complicated and cumbersome in the future. Pay attention to strict time control and protect your own safety.

At present, she plans to make three things, glasses, transparent windows and mirrors, and none of the others will be produced, with these three things alone, there will be enough profits, she is not greedy, and it is good to slowly grow the martial family.

The four mirrors were divided by three women, and Wu Nuandong naturally had no opinion, and it was prepared for them. The last one was for her to give to the female master.

Knowing that Wu Nuandong was busy making new gadgets, even if she was unhappy, Tan Ling endured it, who let herself find a little disciple who was not doing her job, but when she really saw the clearly visible mirror, she realized that her little disciple was not not doing his job, but a genius demon who jumped out of nowhere, and such convenient things were all drummed out by her, what else could she not do!
