Vol 3 Chapter 40: Ceramic pipe network

, The fastest update to the latest chapter of the original wizard!
As for the water pipe network specific to residential houses, Ace learned the lessons of previous Rome and instead of using metals such as lead for water pipes, he planned to fire ceramic pipes, and then use the magic of turning mud to stone for secondary hardening.
The world's ceramic skills have been passed down for a long time. What is lacking is only the glazing skills. The key to firing ceramics is glazing, and the key to glazing is glaze.
The function of the glaze is to apply the vitreous layer on the ceramic blank and melt at high temperature.
This kind of vitreous layer is the key to ceramics. With the vitreous layer, the ceramics become clean, hygienic, waterproof, beautiful, and the strength will increase, and the water from the water distribution tower can be supplied to every household in a safe and hygienic manner. .
Although Ace has seen quartz and limestone in this world, no quartz and limestone have been found near the valley, so he plans to replace it with an ancient glaze.
This kind of glaze is the plant ash that can be seen everywhere, that is, the residue after burning plants. It is light in weight and alkaline. It is often used for composting and can also be used to make porcelain.
The method of making ceramics is not complicated. It mainly consists of four steps: blanking, drying, glazing and firing. After Ace taught Betty the general method, he deployed hundreds of ordinary residents and more than 30 apprentices. Give it to her and stop worrying about it.
Ace returned to his tower and set out to study the interesting topic of magic hand-rubbed flintlocks and brass cannons. He already had a preliminary idea on how to arm mortals.
In the early stage, mortals were armed with the mature gunpowder weapons of the previous life, and then the strength of mortals without magical talents could be improved by a method similar to virtue runes.
Let the armed and promoted mortals be responsible for basic defense, offensive, and security work, so as to liberate wizards from these tasks and better conduct learning and research.
After Betty received the task, she was very serious. She had many discussions with Dana and determined that the diversion canal project would stop near the west wall of Yeguang City. They would build four huge water towers outside the wall, and then use Urn City to surround the water towers. stand up.
The project in the city is to use a network of stone pipes to divert the water from the four water towers to the forty water distribution towers in the city, and then transport it to each household through a ceramic piped water system.
Under Betty's leadership, all the apprentice wizards in the city began to build stone water diversion and drainage channels using secondary chemical mud as stone. As time passed, the water diversion and drainage network of Yeguang City was gradually improved.
In the open space to the northeast of Yeguang City, a group of mortals were firing ceramic tubes, while Lou Silu and several other wizard apprentices cast a spell on the side to reinforce and harden the ceramic tubes.
In a short while, they finished strengthening and hardening the fired ceramic tube, and a few people chatted together.
"How many social practice points do you have?" a young apprentice asked Lou Silu.
"About five hundred," Lou Silu replied.
"Envy you, I only have three hundred social practice points, just enough to enter the university. While there is nothing wrong, why don't we review the secondary rune literature together, ask each other questions and trace runes!" another apprentice said.
"Well, let me ask questions first. There are several kinds of secondary projectile runes, please write them silently."
Several apprentice wizards were tracing in the air together. Some painted very quickly, some scratched their heads and scratched their cheeks. The first-year secondary rune literature class was mainly memorized by rote. You must be familiar with it before you can use it skillfully in the future. Even improve and transform secondary runes.
In the process of construction and learning by the wizard apprentices, the number of hardened ceramic pipes has also increased rapidly, and the water supply pipe network covering the whole city is about to take shape.
While Betty and Dana led wizard apprentices to build water diversion and drainage systems, the research on Ace's magic hand rubbing flintlock gun was also advancing rapidly.
Ace once made magic glycerin, which is a powerful yellow powder of an unstable magic material version. This magic glycerin is more effective than glycerin made from ordinary materials. Ace speculates that magic power plays a role.
For the gunpowder used by mortals, he believes that there must be a certain generation gap in technology, and wizards must master more advanced gunpowder, so he is not prepared to use yellow gunpowder.
Ace plans to use classic black powder, nitrous oxide, charcoal and sulfur in a ratio of 7:1.5:1, and then after soaking, compacting, drying, mashing, and sieving, it is the best granular black powder.
The black powder is powerful enough to fight against ordinary low-level monsters, and the effect is just right for mortal soldiers.
In fact, it is more than that. For many apprentice wizards, it is also a good choice to directly use black powder as a casting material to enhance the explosive power of fire elemental spells.
The flint gun uses the flint impact on the hammer to produce sparks and ignite the gunpowder. What is needed here is to make a spring, which is not difficult for wizards. Making a bronze spring plate is for proficient in fire element spells and has past memories. It's not difficult for Ace.
The spiral spring was quickly made. The difficulty in making a flintlock gun lies in the barrel, which can be quickly made of steel barrels with excellent materials.
For apprentices who use magic, there is almost no problem. Ace easily creates a flame with a temperature of more than 1500 Baidu and melts the iron into iron juice. At this time, use pig iron blocks to stir the iron juice to make it The combined carbon and air produce high-quality steel.
The three hundred steel bars made by Ace using magic, chanting spells, fixed them on the ground.
He used the magic crystal shaping spell to create a large number of magic crystal drill bits, incorporating his own inherent magic power, making the drill bits extremely sharp and strong.
Accompanied by the rhythm of magic, the magic crystal drill bit directly drilled through the steel rod and formed the famous spiral rifle, also called the windmill line. Most of the flintlock guns in the past were smooth muskets, that is, there was no rifling.
The history of rifling appeared very early ~EbookFREE.me~ but the rifled gun bullet was difficult to load and the rate of fire was extremely slow, so it was not taken seriously by the army.
But the role of rifling is extremely good. Although a musket without rifling has a faster rate of fire, it has poor accuracy and a small shooting range.
Rifling can be said to be the soul of the barrel. The function of rifling is to give the warhead the ability to rotate, so that the warhead can still maintain a predetermined direction after it is out of the barrel.
With rifling, the penetration, accuracy and shooting distance of the musket can be greatly improved. It can be said that every rifled flintlock has the potential to become a sniper rifle.
In the previous life, until the invention of the Miner bomb, the problem of the practicability of the rifled gun was solved in one sentence. A large number of old-fashioned smoothbore flintlocks were converted into rifled flintlocks.
Naturally, Ace will not repeat this process. He has directly passed the stage of the musket, using magic to directly make a steel pipe with spiral windmill lines, and overtaking with magical curves. The material and craftsmanship are far beyond the ordinary. Gunpowder weapons, this is very magical and very scientific!
As for the craftsmanship of Miner bombs, it is more of a kind of creativity. The main problem with rifled guns is that the front-loaded bullets are difficult to maintain the air-tightness of the barrel, and the power is greatly reduced.
