The first shipment of natural latex was not very large, and Owen decided to use half the amount to prototype a batch of erasers.Prepare all the raw materials and equipment you need.Sulfur, in particular, is a very important vulcanizing agent.Vulcanized rubber made of raw rubber through vulcanization has excellent properties such as high strength, high elasticity, high wear resistance and corrosion resistance.The unvulcanized rubber becomes soft when heated, hardens and brittles when cold, is not easy to form, easy to wear, soluble in various organic solvents, and is very easy to age and rot.Natural latex is poured into a rectangular mold, acid is added to it, and it is allowed to solidify to make raw rubber.The raw rubber is then taken to a boiler to be heated and baked to soften, and then cut and broken into small pieces, so that the raw rubber and other raw materials can be mixed more easily.Next, the raw rubber can be calendered.This is where the calender will be used, and Owen has already given the task of having Geeta and the carpenter work together to build a human calender.The most important components of this manual calender are two polished and polished rollers, which can be driven by manual hand-cranking.The raw rubber is fed into the calender and the two rollers are repeatedly rolled over and over again, so that it changes from a highly elastic state to a plastic state.During the calendering process, the ground pumice powder is added evenly, which can make the rubber coarse and harder.Other raw materials such as vegetable oil and sulfur are also added to the mix, and then constantly rolled to allow the raw rubber to mix with them.By the way, if rust (mainly iron oxide) is added to the rubber, the rubber can be colored and turned pink, which can be sold to the wealthy as a high-end commodity.During the calendering process, if the raw rubber cools down, it is brought back to the boiler to heat and soften, and then continue calendering.It has to be said that manual rolling can be a heavy physical work.Even though Owen had called in a few of his guards to take turns to hand calender, they were still tired and sweaty and out of breath.Marpel watched curiously and went up to try it out.It didn't take long for her to appear flushed on her cheeks with exhaustion, and the Qi bangs on her forehead were also stuck with sweat.This is not good, it seems that Owen has underestimated the processing technology of rubber, and it is really difficult to use human labor to calender raw rubber, so he has to ask Geeta to build a steam-powered calender.Until then, lizardmen can be allowed to hand calender, they are much stronger than humans in terms of physical strength anyway.After confirming that the raw rubber and raw materials are well mixed, the rubber in a plastic state is loaded into a mold, and then covered and compacted, and wait for it to set.Finally, the shaped rubber is taken out and neatly cut with a knife to cut into many small rectangular pieces, each of which is a qualified eraser.Once the finished product was made, Owen picked up a random piece and experimented with it, not only to easily wipe the pencil handwriting off the paper, but also to erase eraser shavings.In this way, the residue of the handwriting will not remain on the eraser, so you will not get dirty during use.Owen then distributed the erasers to city halls, schools, and other places where there was a lot of pencil writing in need.As for eraser products that you plan to sell to the Twins, you can wait for the next batch of natural latex to arrive.The remaining half of the natural latex is made into rubber gloves by Owen.Due to the limitations of the current technology, the rubber gloves made are thicker, but also better than without any protection, and these gloves are all sent to the laboratory.…… Castle, in the office."
A letter from Duke Eddie?"
Owen couldn't help but frown, feeling a little strange.He hadn't even gone to Duke Eddie to settle the account last winter, but the other party found him first, is there any conspiracy?"
Yes."
Clive carefully handed the letter to the table.After a pause, he spoke again: "Lord Marquis, I have heard a rumor recently, and I have been hesitating to tell you?"
”"Oh?
What's been rumored lately?
You say. ”"About that rumor......"
Clive put on a look of wanting to say something, and finally said it ruthlessly."
Lord Marquis, it is rumored that you have the blood of the royal family of Wales and are the illegitimate son of His Majesty the Old King.""
Huh?"
Owen looked incredulous, "Do you believe this rumor too?"
Clive. ”"I didn't believe it at first."
Clive hurriedly explained: "But it is rumored that you have the silver hair of the royal family of Wales, and you have abundant magical powers, which is proof. ”Hearing this, Owen spread his hands, obviously not interested in this inexplicable rumor."
Alas, although silver-haired people are rare, they are not only silver-haired people from the royal family.Magical power doesn't mean anything, and there is a very low probability that there will be an abnormally large number of demonic powers among civilians. ”Fanny is a special example of how much magic she has, and her parents are very ordinary businessmen."
However, the people of the Eisen family have always been gray-haired, so why did you become silver-haired?"
Clive was confused.How to explain "you ......"?
Does it have to be explained by the genetic mutation that Winster told him?
But Clive didn't even know what genes were, so forget it."
I'm sorry, Lord Marquis."
Clive also thought that he had Owen, so he quickly apologized and found a reason for himself."
Perhaps, your hair color has something to do with your mother, and I shouldn't speculate too much."
In Owen's impression, his mother is not silver-haired!
Forget it, Owen didn't want to continue discussing this rumor, so he waved his hand to Clive: "You stand down." ”"Yes."
After Clive left, Owen reached out and touched his chin, deep in thought, who was spreading this rumor?
Are you trying to frame him?
I really couldn't figure it out, Owen shook his head, picked up the letter on the table and saw that the fire paint was indeed the family crest of the Eddie family.I don't know why Duke Eddie wrote to himself, so let's open it and take a look.Owen then opened the letter, unfolded the parchment, and read the letter."
What?!
You want me to go to the royal capital to have a magic fusion test with the third prince!
”Halfway through the letter, Owen was already surprised.In this way, I wonder if the rumors that Clive heard were spread by Duke Eddie."
What the hell!
It's really ...... that they want to use this method to frame me Eh, wait!
”Owen thought about it carefully, Duke Eddie is not stupid, if he really cheats, it is a big crime to deceive the royal family.Moreover, why was the magic fusion test with the third prince and not the eldest prince?
It seems that the battle for the throne should be over, and it is the third prince who wins.Owen remembered that when Kuros came to visit him earlier, he mentioned that the Eastrise Fortress had chosen to support the Great Prince.Now that the eldest prince has failed, Duke Eddie's move is most likely to curry favor with the third prince.This lord is backed by a tech tycoon
