The ancient technique of glass blowing to make large glassware has become outdated.

Large-scale glassware is mainly die-casting, and the molten glass subjected to such processing also contains a variety of additives, so that the glass does not crack during the die-casting process.

Making glass is a difficult technical task, and Lurik did not dare to expect Clavason's skills, let alone his own theories. Now his biggest advantage over the craftsmen under him is that he has mastered innate knowledge. With knowledge, what is left is constant trial and error in order to achieve one's goals at the current level of technology.

As a result, Lilia struggled to make as many as twenty glasses made by Barra, and they became raw materials. The girl has some regrets. She originally planned to make a batch of glassware and deliver it to her family. She is so young that she has a small brain, knowing that her products can quickly bring a considerable amount of income to the people in her hometown.

Although it is a pity, at present, apart from these ready-made finished glassware, there are too few surplus raw materials, and it is a waste of time to mine and mix raw materials.

Rurik was grateful for Lilia's sacrifice.

However, Lilia regrets it, she would be very happy if she could help her future brother-in-law who is quite handsome.

There is a saying that Rurik was loyal to washing himself. Since soap began to be widely used, his self-washing has become more frequent. How can a clean boy and a sixteen-year-old girl not like him? Besides, this child is already a family member.

In addition, Lilia also wanted to witness a new miracle.

Twenty cups melted into a thick mass of molten glass. Because of the addition of lead oxide, its plasticity became stronger. The huge clay crucible was originally used for burning bronze water, but now it is occupied by molten glass.

In order to process this, the blacksmith's work was completely suspended.

Kravasson personally supervised the melting of the glass. Seeing that the time was right, he shouted: "It's going to begin. Kawei, get ready!"

Immediately afterwards, Clavason, wearing thick leather gloves, hooked the reddish cauldron with huge tongs. He carried the bucket of extremely hot things and hurried to the die-casting machine.

Lilia, who was wearing a leather apron, was all watching. Also surprised were Rurik, and two close buddies Kanuf and Fisk who insisted on coming here to watch the excitement.

Even Rurik has never seen such a scene. He has a theoretical basis in this regard, and everything except for this can only be supplemented by his brain.

What now? The bronze mortar preheated by Kawei was poured into a large amount of molten glass by Cravason.

Kawei, who was quick-eyed and quick-hand, seized the time. When his father removed the almost empty crucible, he grabbed the huge lever with his entire body and pressed it down with all his strength.

The hard shipbuilding oak lever drew an arc in the space, a set of wooden mechanical structure, which transformed it into the vertical force of the bronze punch.

Even if the bronze mortar has been preheated, the hot molten glass is still rapidly cooling down. Kawei didn't waste much time. He pressed the steel rod with his whole body strength, and the punch was completely immersed in the glass liquid, so that a lot of the viscous glass liquid had overflowed and even fell to the ground. The next thing was to wait.

Due to the principle of thermal expansion and contraction, Rurik did not wait long. The glass had cooled to the point that it lost its bright red heat, and it had become transparent throughout, that is, its heat was sufficient to quickly blanch a piece of meat.

Until it had cooled to the point where the craftsman wearing leather gloves could touch it, Kawei carefully put the hot bronze mortar down. It was also due to the anti-adhesion toner that was applied in advance. The glassware was taken out very easily.

In order to prevent it from cracking after cooling, the glassware was deliberately designed with thicker walls. It still needs some annealing treatment to completely eliminate the stress that causes cracking. Until then, Kravasson still has to further process it.

Twenty ordinary glasses were melted, and Rurik had initially completed the first large glassware.

He needed two large containers, and Lilia had to continue to make sacrifices.

However, these sacrifices are worth it.

Next to the stove, Kravasson heated the large glassware locally. The glassware began to heat up again, and this time it was Clavasson who stretched the mouth of its bottle to create a strange shape in accordance with Rurik's request.

It will be processed into glass bottles, and in theory its walls can be processed very thin. Rurik couldn't expect the Cravassen family to master the superb craftsmanship in an instant. The thick walls of the two large bottles also made it possible for the bottles to be stretched further.

Because of the addition of a lot of lead oxide, the glass bottle is actually a little black.

It was originally a huge wide mouth, which was continuously processed by Clavasson, and finally, it turned into a narrow mouth bottle.

In other words, the two bottles became something like a "big-belly long-necked vase".

As the bottleneck was deliberately bent, and the annealing work was completed, the processing of the most critical equipment of the distiller was completed.

The two bottles were on the ground, Klavason was covered with sweat, and his old face was filled with the joy of success.

"Rurik, what should you do now? It seems that you just want to pour wine into the bottle?"

"correct."

"Where is the wine?" Clavasson asked, panting.

"I have discussed it with my father, and I have prepared a barrel of craft ale."

"That's okay, I thought I needed to buy wine in person. Then just pour the wine into the bottle, and then?"

The principles and techniques of distillation cannot be explained in a few words.

Rurik checked the two bottles as usual. In addition to feeling the level of an old friend, he secretly sighed that this guy might as well be a professional glassmaker. He is even more regretful. If Kravasson did not live in such an ancient and wild era, but lived more than a thousand years later, such a talent with strong hands-on ability must be an extremely theoretical and practical person. Excellent national-level engineer.

National engineer?

Cravason is indeed an engineer of the Ross clan.

In this way, the distillation flask and collection flask of the distiller are ready, and the "long neck" that has been deliberately bent is the key to the condensation of alcohol vapor.

A special copper tube was also made by Kravassen, which connects two bottles, and the gap between each other is filled with leather or linen.

It lasted until August 8th. On this day, Rurik was sure that the still he had requested was ready.

Moreover, Rurik did not come by himself on this day. Otto, the leader of the Ross tribe, also took his wine barrel and ran to Clavassen to observe the wonders.

Otto, he was completely moved by the explanation of his son dancing and dancing. After all, he heard that there is a "peerless wine from Valhalla" that can be enjoyed by himself who is still in the world, why not be moved?

Presumably this is the "wisdom of God" that the son gained.

The leader Otto drove over, and Clavasson had only respect for him, but never had any fear of him.

Lilia was different. She had seen the violent side of Leader Ross in her hometown after all, and she couldn't help being in awe.

But when she saw her father-in-law and husband, she could talk and laugh kindly with the leader, and her nervousness faded.

Otto put the wine barrel he was holding on the ground, habitually pulling his son to his side, rubbing Rurik's little head.

However, what shocked the senior leader most was the two large bottles connected by a copper pipe.

Otto! He had never thought that such a huge, completely transparent container that was obviously artificially carved could exist in the world. When he was excited, his hands could not help but actually pinch his son's small face, making Ric's whole body deformed.

"Rurik, this is your...your new baby? Made of pure crystal?"

"Dad... let go! My face is already..."

Otto hurriedly closed his hand. This time he immediately asked Clavasson, who was about to laugh, "My friend, you made these according to my son's request? It should be like this."

"Of course." Clavasson covered his heart with his right hand and bowed slightly, "Big Chief, this is a miracle brought by Rurik. I'm just a craftsman."

"Oh, you are humble."

"No." Kravasson shook his head: "If it weren't for Rurik, how do we see such a huge transparent container that is as clean as water?"

Started commercial mutual buzz again? Rurik was a little upset: "Blacksmith, don't talk nonsense. The good wine is here, let's start quickly."

"Good Le!" Clavasson approached Otto: "Liurik is determined to start, what shall we do next?"

"Let's start!" As the leader, Otto eagerly issued the most critical order.

The reason why crafted ale is crafted is that it has a higher alcohol content. In addition to continuous fermentation, local residents have unexpectedly found a unique way for higher alcohol content. .

According to traditional Nordic brewing techniques, oats or rye can generally produce ale with five alcohol levels. If you want to make a higher alcohol content, there is an effective but demanding method.

Northern Europe is often very cold in winter, even if it is adjacent to the Baltic Sea, it is possible for the temperature to drop to minus 20 degrees at night in winter.

Some families who are indulging in winemaking accidentally put the wooden barrels for storing wine outdoors, but when they were about to drink, they found a block of ice in the barrels.

There is no smell of alcohol at this ice tuft, it is like a piece of ice, and it does not come with the snow that can be seen everywhere.

People drank the uniced part and felt the obvious spicy taste.

Because the freezing point of alcohol is much lower than that of water, it has become the earliest antifreeze that humans can touch and use.

Even if it's just a fifth-degree ale, because of the presence of alcohol, its overall freezing point has dropped a lot. Even if it freezes, the water inside freezes first, and the result is that the alcohol is passively concentrated.

One way to make craft ale is to freeze, so as to passively achieve concentrated alcohol, but the technical conditions to operate this are really harsh.

Anyway, they are trying to get rid of the water in the wine. How can the freezing method have the distillation method to enjoy the fun?

In fact, it is just that the proven distillation technology has not spread to Northern Europe. Now the times have changed!

The first distiller for distilling wine in Northern Europe was born, and it will soon be put into production. Its debut is amazing, because the core body of this set of stills is still two large glass bottles!

Rurik even believes that these two glass bottles are the largest glassware in the human world in this time and space.

Otto personally poured the cloudy and yellow ale into the first glass bottle through a funnel.

The so-called "large glass bottle", the actual volume is not large, only about four liters. To make such a glass bottle in a trivial way, is it guilty of the twenty glasses Lilia has worked so hard to make? The problem is that the glass processing technology is immature, and the wall of the bottle must be very thick. It has been annealed, and Rurik doesn't worry about it cracking.

The distillation process is still guided by Rurik himself.

On the sandy ground inside the blacksmith's shop, a brand new small stove was constructed assault.

The stones built a platform on which the glass bottle containing the ale was placed, and the slow-burning charcoal block was placed under the bottle.

Currently, the bottle full of ale is open, and this is what Rurik deliberately did.

The early distillation equipment was like this, but no one would use glass containers for distillation. In fact, it's not that they don't want to do this, it's just that they just use the traditional technique of glass blowing, and they can't make a glass bottle with a volume of up to four liters. Besides, the craft of glass blowing has been lost in Western Europe, and only Eastern Rome still retains it.

Distilling ordinary ale to produce high-purity alcohol is really a time-consuming and laborious process, of which temperature control is the most terrible.

If there is a reliable thermometer, Rurik feels that his work will go smoothly.

Naihe himself does not have such a magical device, but he still has his own advantage-knowledge.

"The evaporation temperature of methanol is low, about 75C? At this temperature, I touched my hand a little. The evaporation temperature of ethanol is higher. The only thing I can determine is the evaporation temperature of water..."

Methanol is too toxic, so soil burning is not good for distillation. If you drink too much methanol, you can burn too much soil. I'm afraid it won't kill people. It can be said that fake wine is harmful.

Rurik had already thought of a routine, he had already begun to try.

The burning charcoal began to heat the large bottle filled with ale. Through the basically transparent glass wall, everyone could see the changes in the internal substance.

As soon as [] is opened, the bottle is simply heated.

Its narrow, curved bottleneck is always open, and as the heating continues, the smithy is full of wine!

"Ah! I never thought of this before. If I just smelled this scent, I would be very happy." Otto said with emotion, if it weren't for the intoxicating aroma of wine, who would be so loyal to drinking ale?

Rurik was calm, his big eyes kept observing the situation at the mouth of the bottle, and even the changes in the ale in the bottle.

Until the wine in the bottle began to bubble.

Clavasson has been looking at his back for a long time, isn't he talking about good distillation? It seems that Rurik is still simply cooking wine.

He couldn't help frowning and asked, "Is it time? Rurik, when can the other bottle be used?"

"hold on."

"When will you wait?" Otto asked impatiently.

Rurik looked at the people around him. They had no idea about distilled spirits, so they had no choice but to be a spectator. He saw the heated bottle again. The bottom of the bottle had been blackened by charcoal fire. Looking at the wine inside, the bubbles were really increasing.

The room at this moment is already full of wine, and when he put his nose close to the twisty but open bottle mouth, all he smelled was intoxicating fragrance.

The wall of the bottle is already full of breath, and this intentionally made curved bottle mouth, which is deliberately bent into a very small chamber for storing liquid. Rurik glanced intently, and there seemed to be a little liquid stored in this chamber.

He put his index finger into the bottle mouth, a continuous enthusiasm gushing out. I have to say that the gas is really hot and humid. It seems that as long as you put your finger for a while, a lot of water will be attached to the fingertip. It's just that the heat is really strong, and if the finger is placed for a longer time, it will be a terrible burn.

His fingertips touched the chamber, and his fingers hurriedly scratched the inside of the bottleneck.

Then, take out your fingers and **** with your mouth.

The moment his tongue touched his fingers, his whole expression completely changed.

"Rurik, what are you doing?!" Otto keenly noticed the change in his son's expression, and the whole person fell into a state of tension.

"Is there something abnormal again?" Cravason also asked.

Rurik didn't speak for a while, he changed another finger, and continued to poke into the bottleneck, scratching the moist "ha" and then licking it from the tip of his tongue.

After two consecutive attempts, he felt that the spicy sensation in his mouth was not an illusion.

It's wine! And it is obviously spicy.

There is also that narrow chamber, and the little things stored in it are simply high-quality liquor!

Unexpectedly, I succeeded in my first experiment based on the theory I possessed? !

More than that! Rurik felt that he allowed the bottle to keep pouring out of alcohol. The bad methanol in the ale had already evaporated, and even his actions were full. As the ale with huge water content became more and more bubbles, the whole bottle of ale Getting closer to the boiling point, the alcohol he needed was actually evaporating quickly.

Because of his hesitation, part of the precious alcohol has filled the entire room. Everyone was full of praise for the strong aroma of wine far beyond the past, and even Kawei's mother who was in the living room sewing leather was also attracted as a spectator.

Rurik stomped his feet vigorously and commanded loudly, "It's now, let's put the stopper on. The rest of the time is to wait for the copper pipe to condense! And charcoal, continue with the flask."

After Rurik finished speaking, he himself put the cork with the copper tube into the tortuous bottle.

In this way, the heated bottle was sealed, and in order to ensure its tightness, Rurik also stuffed a piece of soft leather. After this operation, the more heat-generating alcohol vapor was mixed with part of the water vapor, and the mixed vapor entered the copper pipe with excellent heat dissipation ~www.mtlnovel.com~ and began to quickly condense.

The good heat dissipation and heat absorption of copper tube also make it an important construction of air conditioner. It may not be the best condenser, but it is undoubtedly the most cost-effective. After a thousand years, people will need it more and more in order to cooperate with the condensate to save their lives in the hot summer.

The condensation process of the mixed steam of alcohol and water in the copper tube is almost instantaneous. No, when the distillation flask assembly is completed in Rurik's hands, the exit of the copper tube is already ticking with crystal water droplets. ".

Is it really a drop of water?

of course not. Rurik had already felt the magical pungent body sensation just now, it seemed that it was not the delicate body of his own body at all, which made his tolerance to such pungent stimuli poorly.

The source of the pungency is alcohol, and its spiciness gives Rurik the same feeling as before.

Vividly speaking, it's like taking a sip of a 72 wine head wine, which is more powerful than the feeling of Erguotou!

Maybe, I should collect this steamy liquor, and then light a fire. As long as it can burn, that is true success.
