Chapter 467

Hearing Xu Leng's words, Bai Xiaohei didn't talk nonsense. He turned to the bellows and held out his hand to grasp the pull rod of the bellows. At the next moment, Bai Xiaohei pulled the pull rod out and then pushed it in again. A strong wind blew out at the air outlet of the bellows, and the fire in the smelting furnace suddenly flourished under the wind.

While Bai Xiaohei began to pull the bellows, Xu Leng had walked to the basin with star sand, and then raised his hand and grabbed it.

Holding the star sand, Xu Leng came to the furnace, and then sprinkled the star sand with water in his hand directly into a small metal pot at the top of the smelting furnace.

When the star sand stained with water came into contact with the fiery red pot, it made a hissing sound, and the water was evaporated instantly. At high temperature, the particles of star sand began to expand rapidly, and the volume was about twice as large as before.

However, in addition to the increase in volume, the star sand shows no signs of melting, and a layer of transparent crystal like crystals appears on the surface of the star sand at high temperature.

While pulling the bellows, Bai Xiaohei looked at the star sand in the small iron pot on the smelting furnace. After five days, he followed Xu Leng to make glass lenses. Bai Xiaohei also had some understanding of glass casting. Star sand is different from ordinary glass sand. The melting point of this mineral sand is very high, According to Xu Leng, the star sand below 1000 degrees will not show any signs of melting, and with the increase of temperature, there will be a special energy called star power inside the star sand, which will form a special protective layer on the surface of the star sand. Unless the protective layer is exhausted, the star sand will not be melted.

Seeing the crystal like special crystal on the surface of star sand, white Xiaohei also knows that this is the key to heating. White Xiaohei continues to hold the bellows with one hand and takes a bamboo tube off the shelf on one side with the other hand.

After taking the bamboo tube, Bai Xiaohei bit off the plug sealing the bamboo tube with his teeth, and then shook his hand so violently to sprinkle the combustion supporting liquid contained in the bamboo tube directly into the furnace of the smelting furnace.

When the combustion supporting liquid came into contact with the burning coal, the flame in the smelting furnace suddenly became violent, and Bai Xiaohei took advantage of this opportunity to speed up the speed of pulling the bellows. For a time, the fire in the smelting furnace was blazing, and the temperature began to rise instantly, not to mention the temperature in the furnace, even the external temperature began to rise significantly, The whole room is as hot as a steamer.

With the temperature rising again, the layer of crystals on the surface of Stardust began to melt like ice and snow. After these crystals disappeared completely, the Stardust with no movement inside finally began to melt.

Star sand is different from ordinary glass sand. After melting, ordinary glass sand is a fire red liquid material, which is similar to magma. Although star sand is also liquid after melting, its color is silver white, and there is a faint pure white smoke floating on it. The smoke condenses and forms a special vortex above the melted star sand.

When all the star sands melted, some silver liquids appeared at the bottom of the melting pot. These liquids were particularly beautiful, and even reflected other colors in the light of the fire. Looking at those melted star sands, white little black eyes even showed a trace of intoxication. Such beautiful things are really worth seeing.

Xu Leng took a deep breath after seeing the star sand melt. The hot air made his trachea and lungs feel hot, but he didn't care. As a glassmaker, his favorite was this hot and slightly irritating air, and only this air could calm him down completely.

After repeated breathing for several times, Xu Leng's mood gradually stabilized. Then Xu Leng reached out and took a small box from one side of the table. The small box was made of model soil and rare earth. A groove has been pulled out in the middle, and its shape is the shape of the hexagonal lens required by white, small and black.

With one hand dragging the mold, Xu Leng grabbed the long handle iron spoon with the other hand, took some directly from the molten star sand liquid and poured it into the mold. However, this time, Xu Leng did not fill the mold directly as he did a few days ago, but poured about half.

When the molten star sand occupied almost half of the mold, Xu Leng stopped pouring, then put down the long handle iron spoon at a very fast speed and picked up the carving knife from the tool table. At this moment, Xu Leng's eyes completely changed and showed an extremely focused look in his eyes.

Slowly raised the carving knife in his hand. Xu Leng didn't act immediately, but stared at the glass sand melt gradually cooling in the mold. With the passage of time, the melt gradually began to solidify and become a semi-solid state. At this time, Xu Leng finally moved the carving knife in his hand and saw him holding the mold box in his left hand, The right hand began to carve on the semi solidified star sand like lightning, and there was no mud and water in each knife.

A moment later, Xu Leng had stopped his action, and a hexagonal hollow carving had appeared on the cross section of the semi solidified star sand melt. Because it had been semi solidified, the notch remained on it so clearly.

Slowly exhale, Xu Leng puts the mold on the workbench, then reaches out to pick up another mold, injects half of the melt as before, and carves the same hollow pattern on it in the semi solidified state.

After all this, Xu Leng turned to Bai Xiaohei, and then showed a smile he hadn't seen in five days: "Xiaohei, I will succeed this time."

Hearing Xu Leng's words, Bai Xiaohei showed a trace of doubt. From Xu Leng's previous actions, he judged that Xu Leng could not directly make hollow patterns in the finished six glass lenses, so he chose to make them in two parts, and then put the two half glass lenses together. Naturally, it is complete, but there is a disadvantage in doing so, That is, after the two glass lenses are combined, there will be a joint in the middle. You should know that this lens is used as the energy core of the soul energy gun. The light transmittance must be good. If there is a joint, there will be an opaque cross-section. How can it be transparent?

However, even if his heart was full of doubts, Bai Xiaohei didn't ask because he believed in Xu Leng. After getting along with him these days, he found that Xu Leng was a very serious person, especially in glass casting. As long as he was in charge of the work, he didn't need the employer to tell him anything, This guy will do it with the highest requirements. Maybe this is the so-called craftsman spirit?

Sure enough, what Bai Xiaohei expected, Xu Leng obviously thought out a countermeasure. After the two half lenses were completely cooled, Xu Leng took them out of the mold and butted the two lenses together. Although they were made separately, the two lenses were perfectly matched after butting, and there was no deviation even in the hollow pattern in the center, If there were not traces of seams in the middle, we could even say that we could not find any problems.

What Xu Leng has to do next is to join the two lenses and remove the refractive surface at the joint. I have to admit that Xu Leng's title as a legendary glassmaker is definitely not in vain. Under the stunned gaze of Bai Xiaohei, Xu Leng used a special skill called remelting and refining to heat and cool the glass lenses repeatedly, In the process of repeated heating and cooling, the joint points in the lens gradually began to integrate, and finally completely integrated. From the outside, it can't be seen that the lens is connected with two half lenses.

Holding the nearly perfect hexagonal lens, Xu Leng's expression on his face was completely relieved. Then Xu Leng handed the lens to Bai Xiaohei and said with a smile: "Xiaohei, I finally live up to my trust. This lens has become!"
