"Father." Gao Yang walked slowly, "Father, my daughter will do a magic trick." ”

"Magic? What is magic. Li Er put down the Rubik's Cube in his hand, and so far he could only put together one side of the Rubik's Cube.

Gao Yang stepped forward and took out a penny, "Father, you see this is a penny." ”

"Hmm." Li Er nodded.

Gao Yang clasped his hands together and shook a penny in front of Li Er, and opened his palm, "Father, how many pennies do you think it is now?" ”

"Huh?" Li Er's eyes widened.

"Hehehehe...... Gao Yang smirked, "My daughter will change her father again." ”

With his hands folded and shook again, the money in his palm became Sanwen, and in the face of Li Er's puzzled and ghostly gaze, Gao Yang smiled and explained, "This is magic, a kind of trick, it's amazing." ”

Hearing the trick, Li Er let out a sigh of relief, "Why did you come to curry favor with me today, did you want to leave the palace again?" ”

"My daughter hasn't been out of the palace for a few days." Gao Yang pouted, "My daughter wants to go out of the palace to see the imperial sister." ”

"Haven't you ever been out of the palace for the big wedding of the green sparrow? You still have to stay in the palace these days, and talk to me again when spring begins next year. Li Er returned to his serious appearance.

"Humph! That's why the queen mother looks at it tightly and can't leave the queen's sight! Gao Yang pouted and left, sitting outside the Lizheng Palace, thinking about what else could make his father happy to lift his grounding, if Gu Qing was here, he must have a way, Seeing a few palace maids sweeping the fallen leaves, Gao Yang stepped forward, "Hey, a few of you." ”

"Your Highness the Princess."

"Her Royal Highness the Princess......"

Several palace maids saluted, and Gao Yang raised his chin and said to them, "Do you leave the palace on weekdays?" ”

"The slaves and maids don't go out of the palace on weekdays, they let the palace servants go out to buy things." The palace maid replied.

"Chamberlain?" Gao Yang had a plan in his heart, "It's okay, you go ahead and sweep the floor." ”

Changle received the words brought out by the palace people, Gao Yang wanted Gu Qing to help find a way to lift the grounding, and couldn't help but smile bitterly in his heart, this wayward sister really couldn't help her, what would his father think if he let his father know that Gu Qing helped Gao Yang find a way to lift the grounding.

In his heart, he still said to Gu Qing about this matter and his own thoughts, "Gao Yang just ran out of ideas for a while, you still don't take it to heart, if your father knows......"

"I understand." Gu Qing nodded and said, his body unconsciously approached Changle, "Changle...... You say we ......"

Just as Gu Qing was about to say something, Sun Simiao passed by and coughed vigorously twice.

The interest was swept away by this old man, Gu Qing got up helplessly, "The matter of finding a teacher for the old man must be put on the agenda!" Staring at yourself all day long. ”

Changle sneered, "Go back quickly, Wu Mei is busy there." ”

When Gu Qing returned home, he saw that Wu Mei was settling accounts, most of the students in Guozijian were from rich and noble families, and many students still paid money to attend classes.

pressed Wu Mei's shoulder, "Madam is fortunate." ”

"It's not hard." Wu Mei said, her body felt wrong again, and Gu Qing's hands began to be dishonest again.

"Don't do this, husband!" Wu Mei pushed Gu Qing out of the door, "The concubine can't do the accounts." ”

Back in his small room, Gu Qing began to think about how to make glaze again, and there was a chemical equation written on the wooden board on the side, finding alternatives from raw materials, limestone, quartz sand, alkali ......

Soda ash is too difficult to refine, so you can only use one with poor purity.

The earliest glass in history was fired, Gu Qing took a small stool at home and waited for the glass to be fired, and after waking up from a nap, the glass of the stove had some color, until the fire of the stove was automatically extinguished.

Gu Qing took out the glass with iron tongs, and the joy in his heart Although the light transmission was much worse, it was already usable, and the color was better than the previous times, and it was really a problem with the raw materials.

"Rich! Get rich! Gu Qing laughed.

The earliest record of glaze firing is in the first year of Kaiyuan, and there are still more than 100 years to go...... Today's glaze is mainly a by-product of the tribute and refining of bronzes from Persia and the Western Regions.

Rubbing his hands excitedly, Gu Qing made many models to burn the glass into various shapes, Liuli's wrists, Liuli's bowls, and Liuli's toys......

It was already late at night, and Wu Mei came to Gu Qing's small room, "Husband, it's not early." ”

With a kiss on Wu Mei's face, Gu Qing smiled and said, "Girl, our family is going to make a fortune." ”

Wu Mei's face was flushed by this kiss, and she was at a loss, "Concubine...... The concubine went to bring her husband some food. ”

Gu Qing didn't sleep all night excitedly, he had been tinkering with the production of glass, it was bleak autumn outside, and the room was in full swing.

On the second day, Gu Qing let the horse pull a cart of Liuli and slowly walked to Chang'an, Yang Sheng came over with his subordinates, "These are all good skills, they can protect you in business." ”

"Good!" Gu Qing took out two glass rings from his arms, "This one is for you to make a wedding gift." ”

"This is ......" Yang Sheng looked at the glass ring and didn't dare to accept it, "This is too precious." ”

"Not precious, not precious at all! I fired it myself. Gu Qing said, "I don't know if it fits the size of the two of you's fingers." ”

"Is this on your finger?" Yang Sheng put his fingers on it, some of the sizes were not suitable just enough to fit his thumb, "You can even fire glass?" ”

"It took a lot of brains." Gu Qing said with a smile.

Yang Sheng looked at the wooden cart pulled by the horse, covered it with a heavy cloth, "The glass on your cart is all glass?" ”

"That's it!" Gu Qing said happily.

"This ......," Yang Sheng gasped, "I'll call some more people." ”

Coming to the east city of Chang'an City, Gu Qing sat on the wooden cart and watched the flow of people coming and going, proud in his heart, lifted the heavy cloth head, and shouted: "Don't miss it when you pass by, sell glass!" Crystal clear glass! ”

Glass! When the people on the streets of Chang'an heard the news, they stopped and looked back, and the people in the audience were stunned, it was really a cart of glass.

The glass has always been owned in the palace, and even the glass in the market is sky-high, and there is a car of glass here!

Gu Qing smiled proudly, how is it? Blind your dog's eyes!

A few people dressed as small servants immediately walked out of the crowd, "Dare to ask this little brother, how to sell these glasses." ”

"The highest price wins!" Gu Qing said, "These glasses are sold one by one, and each one is the one with the highest price!" ”

"The one with the highest price wins." Someone began to hesitate.

There was no shortage of small servants of some powerful people in Chang'an on the streets of Chang'an, and the news immediately spread to all the mansions in Chang'an.

Li Tai was drinking the roasted tea he had just brewed, and he was surprised when he heard the report, "He really made the glass?" ”
