The worldly talent, kind nature, and the golden mandarin duck who dares to act together are full of the aura of youthful children. Looking at it, he is lively and vigorous: "Mr. Cong, why are you always coming and going? The old lady wants to talk to you. If you have free time, go to Rongqingtang, the West Road, and sit down."

"As soon as I come back, I will most likely pay my respects to my ancestors. Sister Yuanyang is so good at telling jokes. I, Jia Cong, are just a concubine's son, and I dare not sit in front of my ancestors often. There is nothing to talk about." Jia Cong turned around and said.

The courtyard between the huge inner and outer ceremonial gates seemed increasingly lonely because of its vastness. The living people were still a little dull under this rigid building. Jin Yuanyang bit her lips, which were originally made of lip makeup, as if she was sighing in her heart, sighing in the past, and the beauty of memories was mixed with desolation, and she said softly: "Last year, Xinsi to Renwu, Master Cong's filial piety day was about half. When the day suddenly became angry, he became old in an instant. Even if the filial piety period was not yet satisfied, there were some things that the old lady might want to arrange to ask about."

"For example, what should the three ladies live for life? Should the family be divided or merged? What impact will Cong's career have on the clan?"

Jia Cong took a deep breath: "Sister Yuanyang is too complicated, even if I sometimes think so complicated. What I can predict is that the variables are too great. It is because of the unknown fortune and misfortune. Therefore, there are more people in this world who enjoy timely. There are also laughter, life and death in the clan, let alone the ups and downs of officialdom, and the morning is not safe. They have to shout thunder, rain, dew, all of which are the kindness of the king? But no matter what, I have to do my best to clear away the so-called fog. I still remember the two sentences of "Zengguang Xianwen" compiled by me: Children and grandchildren have their own blessings, don't be a horse and cow for their children and grandchildren. The old lady is worried or not, Yuanyang, don't you think, can she still give the three ladies happiness, happiness and happiness?"

Yuanyang couldn't say anything wrong with Jia Cong's words. Even Jia Cong called her name directly, she didn't dare to say anything, but thought it was like this. You should know that she went to Jia Lian's house, Jia Lian was also polite to her. She thought about it and took out the spirit of her partnership with Wang Xifeng when Liu Laolao entered the Grand View Garden and smiled: "You shouldn't say what's there or not. Just say when will you come and pay your respects? Or will you go later?"

"I'm sorry, I'm very busy now." Jia Cong said embarrassedly, but he didn't know if he was embarrassed to pretend.

"What are you busy with?"

"You should have heard of it. If you don't know, that's best." Jia Cong said: "As for the current expenses, it won't last for a few years, right?"

"No wonder my wife asked Qian Hua and the others to get a share of the matters in the field. Mr. Cong, your sister, although you are thrifty in your house, you can do your best to deal with the court, and you can pay some money. The savings are not enough, unless the officials from other local governors continue to give you big gifts, but in this way, Mr. Cong is very dangerous in the officialdom... My grandmother, the third girl of Ping'erzhu, and your grandmother have roughly calculated the accounts. The money has been paid in more than a hundred years in recent years.

But if you have more money shops, shops and factories, including the above mentioned models, there are still many more money shops, shops and factories. If you want money in the palace, you only need tens of thousands or tens of thousands of yuan. It’s not that you only have one eunuch, but it’s not okay to support it. This is also one of your ways to protect your life and official positions. "Yuanyang knew that Jia Cong was a wise man, and he also knew that he was also a wise man: "So, when it comes to stable savings, one is an old lady, and the other is you... my mother. Of course, the old lady doesn’t have much source of income, but she goes out a lot."

"Thank you." Jia Cong looked at her red eyes and said sincerely.

"What do you thank me?" Yuanyang's oval face was full of doubts and wonders. She considered Jia Cong's difficulties, just as when Wang Xifeng was in charge of the family, she went to visit him. However, she didn't know that Jia Cong had already walked out of the Waiyi Gate at this time. Yuanyang was melancholy and melancholy for a moment, and didn't know why. But when she thought that she had already left Jia She's devil's clutch for life, she finally felt relieved.

Jia Cong agreed to Feng Ziying's request and took him to visit the glass factory. Glass is a new name, and ancient glass contained glass. It was a poor Nancheng place, with old factory walls and soldiers on duty. It was very hot. It seemed that before you could walk in, you could feel the temperature of the crucible furnace hundreds of times. Carbonite (coal), quartz stone, realgar, orchid, etc. were occasionally transported in in large quantities.

"Glass, is this thing magical? Brother Zi Lishi, if I were to make glass, I would have tens of thousands of capable people in China. Why bother to invite foreigners?" Feng Ziying was disappointed and confused.

Jia Cong avoided answering, Shan Ziye extracted some historical materials and books, and asked Jia Cong to refer to them. Jia Cong nodded while reading, "Brother Feng Shi, what you said is not without reason. There were a large number of glass unearthed items in China, China, the Warring States Period, and the Western Han Dynasty."

Christopher, who was supervising, obviously did not believe it. The minor official of the Ministry of Works held up the unearthed objects. The still a bit unruly Dutch Matthewys and Portuguese Christopher looked around. The first person to speak was the British James: "I claim to be proficient in various disciplines. Can Lord Jia know the chemical composition in him?"

"His Excellency James, according to your popular chemical elements, our Warring States and Western Han Dynasty were lead-based glass, pbo-bao-sio, and later potassium-based glass. Baking my country's most important ore galena (pbs) can obtain lead oxide (pbo). By smelting lead oxide and quartz together, we can obtain glass (needs 900 degrees Celsius)."

As an expert, Yamakono nodded slightly, and the others listened quietly. Foreigners were a little worried. This vast Eastern country had glass hundreds of years ago in the Age of Jesus? Is this true God? Although this glass is not exactly the same as theirs, some glass unearthed from other eras have bubbles, green or blue.

"Anyone with some basic mineralogical knowledge knows that galena is often symbiotic with barite. Therefore, the lead oxide obtained by symbiotic ore through oxidation and roasting must contain barium oxide."

"The green and blue glass is because the ore used contains copper, which everyone should know."

The minor official from the Ministry of Works handed everyone a historical editor. Yamakono said: "Looking at the "Records of the Grand Historian? Biography of Merchants" and the excerpts of "Book of Sui", we can see that Jia Cong was not wrong. As for the chemical elements, I am still learning, so it should be the first in the court to Jia Cong."

"During the reign of Emperor Renzong of the Northern Song Dynasty, Li Jie was ordered to write the "Creation Methods", which clearly recorded the material formula for glass: three kilograms of yellow dan, three kilograms of copper powder, and one kilogram of Luohe stone."

When everyone listened to Xunshan Ziye's words and looked at the excerpted historical materials, Jia Cong continued: "Based on my own research and the hard work of the people and friends below, I think copper powder is used for coloring. Luohe stone is a very pure quartz stone, so I agree to use Luohe stone in Mentougou, Beijing (the silica content of Luohe stone in Mentougou, Beijing is more than 90%. Huang Dan, anyone who comes into contact with Taoist priests understands (pb         ??o4).

"After the Tang Dynasty, there were saltpeter, sulfur or borax (na2b4o7                                                                                                                                                                                                                                                  �

"The "Xuzizhi Tongjian Changbian" contains the fact that in Renwu, Emperor Shenzong of the Northern Song Dynasty, Jia Shiming offered a method to burn glazed tiles, which was very cost-effective. So the Song Dynasty court rewarded him with 500,000 yuan, and among the ingredients used by Jia Shiming, there was yellow elixir."

"Today, we can also use the nitro alum method, that is, frying saltpeter, alum [kalso4                                                                                                               

Jia Cong knew that the last method of glazing was more complicated because there was alumina in it. He whispered to Feng Ziying: "It is always right to communicate with each other. What we need is to bring their science and technology. We have technology, but lack science, so that technology will always die."

Just as foreigners were amazed, Shan Ziye flattered and said: "This year is also Renwu. I think the achievements of Master Jia Xueshi will not be lower than that of Jia Shiming of the Song Dynasty."

James, William, Matthew Ess, and Christopher looked at each other. What surprised them was not only the history of glazed glass in China, but also the "chemical elements" that seemed to be more reasonable than what they used. Could it be that Jia Cong was still a scientist?
