"The stress of your glass is caused by heating. Let's first make a piece according to normal, measure the most stresses generated in those temperature segments, and then anneale them in this temperature segment."

Standing in front of the stove, Im told Jia to arrive.

Jia nodded and said that he understood that after preparing the raw materials, he had to start making glass. Suddenly, he thought of something and asked: "Teacher, how should I know what the current temperature is? There is no way to measure it like the length."

Im was stunned for a moment before he realized that he had not taught him how to measure temperature. Jiayi was so mature at ordinary times, and he thought he would have known it long ago.

"I forgot, I will teach you the magic of measuring temperature first. This magic is actually a ruler. By sensing the temperature through mental power, and then changing through magic, the temperature can be identified."

"Isn't that the magic double-opening? I want to maintain the 'Master's Touch' and the temperature measurement magic at the same time. Can it work?" Jiayi was not very confident.

When he had just learned the touch of the mage, he tried double casting, but the two tentacles could only do one thing at the same time. The kind of soldiers he played Warcraft, could only control one line of troops, and could not even control heroes and soldiers separately. So even a simple computer, he never won, and later he never played again. He only played dota maps, and had to be the imba version...

"You will know after you learn it, it's very simple." Im was full of confidence in Jiayi.

But Jiayi also felt a sense of crisis. Every mage can be said to be one in a thousand or one in a thousand. They are no worse than Jiayi, a time traveler. The only difference is probably that they have not experienced the influence of the Internet tide, have seen various routines, and have also been a 16-year study career.

If you cannot develop some relatively high-end skills and improve your competitiveness, don’t say you can win the white and rich beauty, and reach the peak of your life. It’s good to not be eliminated.

"Don't be proud, you are not the protagonist." Jiayi warned himself.

This magic for measuring temperature is called temperature perception, and it cannot even be considered a magic. Strictly speaking, it is an application of mental power. Mental power is very sensitive, and as the temperature changes, mental power will also change subtly. However, this change is very weak unless the temperature changes very violently.

Temperature perception amplifies this change and quantifies this change and directly feeds it back to the mage.

Jiayi learned this magic that day. As long as he meets the mental power and can use it proficiently, it is still easy to learn.

The form of this magic in my mind was particularly like NDA, with many rune spirals intertwined together. Jiayi put a wisp of mental power through the rune and reached the cup in front of him. He instantly felt that the rune had feedback back a quantitative temperature. This feeling was completely different from a thermometer. He clearly didn't see anything, and there was no virtual thermometer in his mind, but he completely understood the temperature of the cup.

This magic not only amplifies the temperature change, but also quantifies it mainly. It also uses the boiling temperature of ice water mixture and water to indicate the temperature limit, just like Celsius.

After Jiayi learned temperature sensing, he did not rush to test the stress relief of the glass. Im and himself thought they should be familiar with it and be more proficient in it.

After learning this magic, it was like carrying a thermometer with you, and it was an all-round thermometer, which could measure the temperature of anything. Jiayi felt that he was curious about the temperature of everything. No matter what he saw, he would throw a temperature sense over and measure the temperature.

He still remembered that his brother once bought a thermometer, a thermometer, a mercury one. At that time, the gray dictionary was raging, and everyone was very nervous. The reading of the thermometer was skilled. At that time, he only saw that the doctor had used it and did not know that he needed to find the right angle to read it correctly. After he used the thermometer to measure his body temperature, he could not see the specific value. He thought the thermometer was broken, or the temperature in his body was not obvious enough, so he did not measure it. Then, he took a corn that had just been out of the pot, put the thermometer on it to measure, and then it exploded.

After his brother taught him how to read, he saw that the temperature was 42 and reached the peak...

The next day, after Im and Kaichi made a new preparation, they began to make glass again.

Jiayi first molten the raw materials to make a glass liquid, and then he took out the liquid glass and molded it into a flat plate. At this time, Im began to sense the stress changes of the glass.

Every time the temperature drops, the stress in the glass changes. Im recorded in detail the change of stress at each temperature. The stress does not change linearly with the temperature change. When the glass first starts to condense, the most residual stress remains. As the temperature drops, when it reaches about 550 degrees, the most stress accumulates. After this temperature point, the glass temperature continues to drop. Although the stress also increases, it will gradually fade when the glass completely cools.

After repeating it twice in a row, Im recorded the stress changes in the glass and gave it to Jiayi: "This is the stress change table in the glass. According to this record, it is possible not to use magic. When the glass solidifies, you maintain this temperature for a period of time, so that the temperatures inside and outside the glass are consistent, and it is enough to keep the heat in half a standard. After the insulation is completed, you are slowly lowering the temperature. With the current size of glass, it should be able to slowly reduce it by about 10 degrees every half a quarter of an hour, which should ensure that most of the stress residues are removed."

Jiayi asked: "Why can you do without magic?"

"As long as your temperature drops slowly enough, you are not afraid of wasting time. When annealing, you are afraid that the temperature changes too quickly, so it doesn't matter if you are slower."

With magic, you can only control the nodes of temperature changes and make annealing more efficient. It would be convenient to use magic to directly eliminate stress, but unfortunately Im didn't learn it.

With Im's advice, Jiayi can finally make a suitable glass. But first, he wants to ask Im to build a new furnace specifically for annealing.

Because the temperature needs to be slowly lowered during annealing, the original furnace is not suitable. Heating a high-temperature furnace can be done, but controlling the temperature to slowly decrease is a bit difficult. Moreover, if you anneale directly inside, then every piece of glass is made, it will be too wasteful.

But it takes time to build a new stove. In fact, Im has no spare time recently. He has been busy with purifying the magic circle. It is already a thankful thing to be able to take time to help Jiayi deal with the stress problem. First, he has been too busy recently and needs a break and change his mind. Second, he really loves Jiayi.

But it is impossible for Im to put down what he has to do to build a furnace for Jiayi. The mage is all self-centered, and even Jiayi himself will not put other people's affairs ahead of him.
