Speaking of which, Owen was trying glassblowing for the first time.Before the temperature cools down and the glass transforms into a brittle solid, the liquid glass is blown into its desired shape.After that, the molded glass is knocked off the blowpipe and then put into the annealing kiln for annealing, which is to eliminate the phenomenon of cold explosion.Glass is subjected to intense temperature changes and shape changes during the molding process, which can leave thermal stresses inside the glass.This thermal stress can reduce the strength and thermal stability of the glass.If it is cooled directly at room temperature, it is likely to break up on its own during the cooling process or during subsequent storage, transportation and use, which is the phenomenon of cold explosion.Annealing is to keep warm or slowly cool down for a period of time in a certain temperature range to eliminate or reduce the thermal stress in the glass to the allowable value.Only after these steps can the final glass product be obtained.Originally thought that the blowing process would be easy, Owen still underestimated the skill after all.The glass bubbles he blew out were asymmetrical, crooked, and the walls were unevenly thick.No matter how Owen adjusted, in the end, the glass still fixed its shape, and obtained a failed product, and even the next annealing process could be avoided.This failed work looks like some kind of indescribable filth excreted from the human body.Looking at the glasswork he blew out, Owen fell silent, it seems that this glassblowing technique still requires a certain amount of skill.Perhaps you should start by making a glass mold with Geeta, which will be easier to blow into the mold.Don't be too arrogant and try to blow without mold as soon as you come up.Fanny leaned over to take a look, forced a calm face, and said, "Well, my lord, I believe you, glass is indeed made of sand. ”"Poof!
Hahaha-" She couldn't help but laugh after all, "but what kind of look are you blowing, it's too funny!"
Hahaha-" Seeing this, Marpel on the side frowned and retorted unhappily: "Fanny, what do you know, this is a work of art!"
Owen-sama did it on purpose!
”She said this because she remembered that she had seen a strangely shaped glass object auctioned as a work of art at auction, and finally sold for a very high price by a wealthy man.Alright, Marpel, thank you for defending me so much, Owen was touched in his heart."
Ahem!"
Owen faked a cough, "Fanny, wait a minute, please re-melt it, do you remember the mana output at that time?"
”"Of course I do."
Fanny nodded.Owen knocked the product off the blowpipe and put it back into the crucible in the kiln, and then handed it to Fanny.Since there is no mold, Owen is not going to continue to challenge moldless blowing, it is a waste of time, he is going to find someone who is good at glassblowing.When Owen remelted the glass at home and planned to make it into experimental equipment, he asked someone to help blow it.The guy only tried it once, and soon found the doorway, easily blew out the desired shape, and made it into qualified experimental equipment.It was also that time that gave Owen the serious illusion that glassblowing seemed easy to learn.With Marpel with him, Owen hurried to the machine room.Upon learning that the lord was coming, Geeta hurriedly stopped what she was doing and came over to greet her."
My lord, what do you want this time?""
I'm looking for someone to borrow from you.""
I'm going to borrow someone again."
Hearing this, Geeta looked embarrassed and reached out to grab her messy hair."
Huh?
Don't you have enough people here?
”Owen said, "Didn't I ask you to take in a few more apprentices?"
”Geeta explained: "There are several new apprentices, but they are not skilled enough, and most of the people you want to borrow are apprentices who have been with me for a long time, and when they leave, the work on my side will slow down." ”Not long ago, he borrowed two apprentices to operate the machine that made warheads and shells, which has already had a certain impact on Geeta."
Ah, this ......"
Owen thought for a while, but still said: "Geeta, the new task on my side is still very important, you can give the new apprentices more opportunities to train, it doesn't matter if you slow down, when they are proficient, the speed will naturally come up." ”"Alas—" Geeta sighed helplessly, "well, my lord, who are you going to borrow this time?"
”"Rob.""
Please wait a minute."
With that, Geeta turned around and shouted inside, "Rob!
Come over to me!
”"Oh——!
I'm coming!
”A young man with freckles on either side of his cheek hurriedly trotted over.Seeing Owen, he bowed solemnly: "Hello, Lord Lord." ”"Rob."
Geeta patted Rob on the shoulder and admonished, "Lord Lord has an important task for you, you have to do it well." ”"Uh-huh."
Rob nodded like a chicken pecking rice, "I will." ”"Then come with me, Rob."
Owen urged.The three of them hurried back to the glass melting furnace.By this time, Fanny had remelted the failed piece made by Owen, and a uniform, bubble-free glass liquid had formed inside the crucible."
Your lord, you're finally back, come and have a look, okay?"
Fanny said urgently.Owen glanced over, nodded and said, "It's okay." ”Hearing this, Fanny retracted her magic with confidence and stepped aside.Owen picked up the hollow iron pipe, handed it to Rob, and said, "I'll leave it to you, Rob." ”Taking the iron pipe, Rob saw the glass liquid in the kiln and suddenly said, "Oh!
It turned out that they were looking for me to blow glass, that simple. ”As in the previous operation, the iron pipe is inserted into the crucible to pick up the material, and then the spoon is rolled.Before he started blowing, Rob turned his head to look at Owen and asked, "Excuse me, my lord, what do you want to make the glass look like?"
”"Then the flask."
Owen responded."
Okay."
Nodding his head, Rob took a deep breath and began to blow at the other end of the iron pipe, turning while blowing, the speed of rotation was very smooth, and the thickness of the glass bubble blown out was uniform, and it was still a perfect spherical shape.Immediately afterwards, he continued to rotate the iron pipe at a constant speed, quickly squeezed out the shape of a bottleneck with the iron clamp at the tail, and then let the end of the bottleneck quickly dip some water, so that the glass at the end quickly cooled, and then immediately knocked it off, pinching out the shape of a bottle mouth.Then use an iron clamp to clamp the bottle mouth, slowly lengthen the neck of the bottle, and the shape of the flat-bottomed flask is basically determined.Finally, the flat-bottomed flask is knocked off the blowpipe, the bottom of the flask is pressed on the rolling plate, and it is flattened and placed in the annealing kiln for annealing.This set of movements is carried out in one go without the slightest pause.This lord is backed by a tech tycoon
