Carefree Prince In Tang Dynasty

The cleaned sand is pushed into the furnace, first dried at a relatively low temperature, and then the ingredients are also sent into the furnace, heated up to melt, and finally cooled to shape. This is the general procedure for firing glass.

Knowing this, at least the glass can be guaranteed to be fired, and the quality is definitely not inferior to the one Wu Zhen just held. However, there is still a long way to go before Li Xin wants to burn out the glass that can be used as a microscope lens.

First, these glasses must be colorless. This requires that impurities be fully removed during the forging process, and no metal ions can be mixed in the formed glass, otherwise different colors will appear due to different metal ions.

Second, these glasses must be transparent. On the basis of fully removing impurities, the temperature control should also be perfect. Otherwise, the burned glass will be full of large and small air bubbles. It is not beautiful enough to be used as a cup, let alone used as a microscope.

Wu Zhen was very thankful that he threw away that piece of colored glaze without hesitation. Because after only a few hours, he really saw a pile of colorful colored glaze being continuously produced from the furnace.

Sure enough, the prince will not lie. Even if it is a treasure like Liuli, as long as he says he can make it for you and pile it up in front of you, then it can really be piled up into a hill.

Wu Zhen was in speechless shock, but Li Xin was still very dissatisfied with the glass, shaking his head constantly with a rather disappointed expression. Every time the glass came out of the furnace, he just took a look, then shook his head and waved his hands, asking someone to pour it out.

Seeing these precious colored glazes being smashed and discarded in front of him, Wu Zhen felt a little pain for no reason—although he witnessed the whole process of turning the worthless sand into colored glazes, he still subconsciously felt that colored glazes were quite precious.

Li Xin stayed at the metallurgical base for three days. Obviously, it was just burning glass that he was fairly familiar with, but he often encountered unexpected difficulties during the experiment. Fortunately, he succeeded in the end, and burned out a large piece of pure, transparent and bubble-free glass.

"It finally worked." He breathed a long sigh of relief, and said to the experimenter who was busy recording the data, "Have you written down the temperature, the ratio and so on?"

The experimenter nodded.

"Okay, burn it again according to this condition, and see if it can be successful." Li Xin said.

While a group of experimenters were busy again, Wu Zhen was already squatting beside the two-foot-long glass block, staring dumbfounded.

"Such flawless colored glass" Wu Zhen couldn't help reaching out to touch it, the cold touch made him feel his heart beating faster for no reason.

In the past few days, seeing the prince repeatedly spoiling those excellent-looking colored glazes, Wu Zhen was already numb. However, seeing such a perfect and large colored glaze with his own eyes, he still couldn't help being a little shocked.

Seeing Wu Zhen's unpromising appearance, Li Xin shook his head amusedly. He knew that Wu Zhen needed time to get used to Liuli, or the fact that glass was not a treasure at all.

"What... go and help me find some craftsmen who can carve gemstones." Li Xin ordered Wu Zhen, "The higher the craftsmanship, the better. The reward can be more, I need it urgently."

Hearing this, Wu Zhen came back to his senses, and hurriedly stood up and replied, "Yes!"
