It turned out that the old man was the son of a person who originally worked here, and the person who burned the glass before was transferred by Yao Huo to do casting, and the people used to do that, but Yao Ran said that he wanted to burn the glass before he was arranged here. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

But the workload here is small, not to mention, and there is nothing to see in the things, but this is the work that Yao Ran has explained, and someone must guard it, so the previous people went back to work overtime to do high-paying jobs, and the old man was left alone on the side of glass firing, and the old man was bored sitting here, so he hugged the little grandson over.

"Patriarch, that I am, that one is here for that one, for that golden grassroots, so I am still not a worker in the blast furnace camp." The old man explained his origin in a hurry.

Yao Ran laughed when he heard this, and then said, "I can see it, it's okay, it's a good thing, it's just that this glass burner requires patience, you have to sit hard and endure the temperature." ”

Burning glass is different from cast iron, it is relatively slower, and the quilts before you can exert your strength are all molded upside down. The surface is uneven, with some bumps.

Because when Yao Ran pressed the glass at the beginning, he directly pressed it with grooves and smooth plates, and then made a whole fast large glass, and then cut and polished, although it would be damaged, or cracked during cutting, or there was a problem during grinding.

But glass has the same advantage as ironware, that is, it can be remelted and reused. There will be no loss, not to mention that it can be purified again.

The old man listened to Yao Ran's words, and quickly nodded, "This is very good, I feel that I can live a few more years, and I am very happy to see my little grandson grow up." ”

"The old man wants to live a long life and be blessed, and when the time comes, you have to find a wife for your grandson. I'll split your work, and you'll burn glass here in the future, and I'll teach you a way to make more interesting glass, and if you're done, I'll allow you to take apprentices here. What do you think? ”

The old man is allowed to take apprentices, which is double the salary, and many tasks can be done without having to do it himself, such as cleaning or raw material screening, and the work of washing can be handed over to the apprentices to do.

The old man himself only needs to do his own work, so that he has two jobs: taking apprentices and firing glass.

There are only a handful of people who can take apprentices in the blast furnace, and Yao Huo is the first student to take disciples in the Yao clan. Most of the remaining apprentices are skilled workers or teachers from schools.

Yao Ran turned out to be such an identity as an old man, of course the old man was excited, and then said excitedly, "I like this thing very much, so I studied it myself, so I burned it, the thing you said taught me again, I looked at it to see if I could learn it." ”

The old man trembled a little because he heard the good news. You must know that there are only so many official jobs in the blast furnace camp, and they are not recruited like external notices, but only recommended when needed.

Because there is no place for the blast furnace camp to supply the population, and many jobs require a technical foundation, such as the recent blast furnace camp has a lot of students. It's not that they are recruited, but they are selected directly from the school.

Therefore, such a job is of great significance to the old man, whether it is income or social status, it is a good recognition.

But this kind of work is because no one values it, and no one likes to do glass-burning work.

Existence is reasonable, and since Yao Ran let people set up this shed, it was not just to make so many glasses and the few cups he made when he left.

Fortunately, they did not evacuate everyone, but left an old man to guard them, and it turned out that this old man really liked the work of burning glass.

In this way, Yao Ran can be regarded as someone who has developed this branch of things, and the use of glass is an indispensable thing in future technology.

Whether it is a building or a means of transportation, or a variety of instruments and meters, experimental utensils, daily necessities, glass is an indispensable thing.

Therefore, Yao Ran can't just give up the progress here, although now Yao Ran can't invest too many resources to study here, because some things are unattainable, and when some specific materials are not discovered, it will naturally hinder the development of a certain technology.

But Yao Ran is also very helpless, because science and technology are not the product of a certain ability, but need the common development of the whole society.

The leapfrog level of science and technology, even if it exists, can only be a theoretical science, without experiments as evidence, and when there is no practical product landing, it can only be a doctrine or theory.

Yao Ran can directly use the retinal system to see the melting of the raw materials in the crucible, but Yao Ran has to tell the old man some simple methods, so that he can be regarded as teaching the old man how to burn glass.

So Yao Ran started, but the retinal system will directly give Yao Ran, the glass melt, the temperature after melting, and there is no way to directly give the old man a description, unless there is an industrial thermometer.

But not in terms of temperature and color, the control can be controlled in time. Control the furnace temperature, how high the flame is, and how long it will be fired.

Yao Ran called up the data in the retinal system and then said to the old man, "Look, you have to remember one thing, it is time!" ”

Speaking of time, Yao Ran was confused again, there is no thing to time, and people can't always count in front of the stove, there will always be fast and slow counting.

Glass time, as if there is something that can be timed. To the hourglass! You can use the hourglass to time, although there will be a slight error, but it will not have much impact, as long as the sand is well chosen.

Yao Ran used gauze to filter out some suitable sand, and then burned an hourglass with glass for the old man to use, and an hourglass was just the time it needed to be fired at a constant temperature. Moreover, if such an hourglass determines a time period, it is also a good tool in the absence of a mechanical watch, and it can also bring a market to the glassmaking industry.

As soon as he said it, Yao Ran took out the iron pipe he had just taken, took out the crucible he had just put in place with gloves and took out the stove, and then dug out a spoonful with a small crucible pliers. Then Yao Ran put this piece of glass on the end of the finger-thick iron pipe. Now it's time to start blowing glass.
