On Ningrong Street, Sun Fu took over the shop that originally belonged to Leng Zixing, but Jia Cong, who got it, was not interested.

The big family is a small court, there is an uninterrupted open and secret fight, the defeated will go out, roll up and leave, this is a common thing, Ningrong Street has a good geographical location for him, and not to mention the governance of the house and the visits of the women, how can he let it go?

At noon on this day, after the family members had cleared the craftsmen and workers, Jia Cong and the women all wore cotton jackets and came in to visit.

Shi Xiangyun and Xue Baoqin all rushed over, and Shi Xiangyun often came.

The storefront, which originally belonged to Leng Zixing and others, was established as a workshop, and the plaque "Glass Cellar" was inscribed, and Jia Cong didn't even call it a glass factory at all, this is his own glass cellar.

The women only dared to follow him and watch, most of them were curious, they saw that there were ten crucible furnaces here, and some of the crucible furnaces only had soda ash, limestone and quartz, or they could only distinguish under Jia Cong and Xue Baochai's explanation, Xue Baochai could dictate hundreds of painting pigments, many of which were minerals.

Some crucible furnaces have different proportions of soda ash, limestone, and quartz stone; Some crucible furnaces have borax or feldspar added to them, and Jia Cong explains which glass recipe is best to use.

Jia Xichun was surprised: "Each process has to be experimented and scrutinized for a long time, right?" ”

"Well, you can say that, so you can say." Jia Cong nodded and said: "The process is similar to that of making eight strands, they are all tested and polished step by step by collecting the experience of predecessors, and there are many glasses made by our ancestors, but they are not suitable for me, and some of them have been lost." I had to go up and down......"

He also collected the experience of future generations, of course, these are only known to himself, and it is inconvenient to say.

Jia Xichun smiled: "Brother Cong is too powerful!" No wonder Miaoyu is such a tall person, and he looks at you differently! ”

This time, it was Jia Cong's turn to be surprised: "Isn't she in the western suburbs of Baiyunguan?" Could it be that you often associate with her? ”

"Not really." Jia Yingchun explained: "Miaoyu was originally invited by my family to enter the Lucui Nunnery, and after the death of the eldest master, she also came to help with the practice, which could have been done often, and the fourth sister often played chess with her for some reason. ”

In the glass cellar, Jia Cong also designed an annealing channel, next to the fired glass, there were several bags of red ore extract, Xue Baochai scratched with a stick, and said, "Is this saltpeter?" You are not making gunpowder here, so why do you use it? ”

"Sister Bao, have you seen that the previous glass and glass are colorless and transparent?" Jia Cong asked.

Xue Baochai said: "It seems to be only available overseas, but it has never been seen in China." ”

"This is because my Shenzhou glass is colored, and in the hot glass water, there is iron in it, according to me...... Regardless of whether it is green or other colors, as long as it is colored, such glass is not suitable for testing equipment, telescopes, reading glasses, glasses, dressing mirrors, etc., to improve the lives of people in the world. Jia Cong said that what he said was the important role of optical glass, which not only changed life, but also changed art, such as cameras, optical drawings, etc., as well as military aspects, which is why he spared no effort to make glass.

"I see...... the girls said in unison, Shi Xiangyun said: "Then how does Brother Cong know this?" ”

"I'm knowledgeable." Jia Cong shrugged his shoulders, we can't say that we are crossing, right? Crossing will not point to black technology, are we embarrassed to cross over?

Lin Daiyu's eyes sparkled: "How long will it take to produce a few sets of glasses?" ”

"It's coming, just wait a few days." Jia Cong replied, and then the craftsmen came in to work, and the women were inconvenient to stay, so they could only retreat inside to read the account books and the like, talk about the housekeeper's affairs, poetry and book knitting, etc., and they were still unsatisfied, but compared to the previous stagnation in the boudoir, they are now "a big step" as Armstrong said.

Then Jia Cong carefully supervised the work, and there was a very important step, which was to remove the bubbles in the glass, Jia Cong called Christopher and Mattheis over, and said: "After the glass is fired, it needs to be clarified, and a clarifying agent is added, such as table salt." However, when the clarifier is exposed to heat, it will form large bubbles, and its upward process will bring out small bubbles, so the bubbles are difficult to remove. ”

"So, stirring the molten glass before it cools can overcome this difficulty, and do you Tessie do the same? Has it ever leaked out? ”

"Not bad." Mattheis said, "Your Excellency, it is true that it is constantly stirring. ”

Christopher said: "Eventually, it will leak out, like we are now, it's just a matter of time." ”

Jia Cong: "......"

"Then we'll make a lot of money before it leaks out, and secondly, we have the money, the talent, and the technology, and we're more experienced, so we can stay ahead of the curve." Jia Cong is categorical.

The two foreigners were silent after going down, and they were obviously aware that Jia Cong had sent musketeers to secretly spy on their foreigners' movements, and the two of them talked while leading the craftsmen to stir, "In this case, it will be difficult for us to go back." ”

Mattheis said, "You Portugal may have been taken over by the Queen of England, and we may be the same in the Netherlands." Don't forget, Henry VIII of England and Mary, the daughter of Catherine, ascended to the throne of your Iberia, and Mary was married to Philip II of Spain, and after her death the bells rang in London. However, the person born to Mary's half-sister, Henry VIII, and Queen Catherine's maid-in-waiting, Anne, ascended to the throne, and she was Elizabeth I. ”

"As you say, but I will not forget the mission of the kingdom, just as our men were the first to reach Arabia, and the voyage and opening up represent death."

"Then don't you consider choosing another master, as the Orientals say, good birds choose trees to perch." Matthewis.

"Your Excellency can go by yourself."

After vigorous stirring, Jia Cong ordered to start using a teether to mold the glass.

The molder is made of pig iron and coated with a layer of charcoal powder blended with tung oil to prevent the mold from sticking to the glass.

The molten glass is cooled through the annealing channel, and then poured into the casting mold, and the craftsman presses the molder, and the molten glass is formed.

The Zunhua Iron Factory is in Gyeonggi, and it is not difficult for Jia Cong to need some iron, so he passed through the original glaze factory, and the glaze factory in Nancheng was approved by the emperor, and he took a part of it from there.

After adding salt and stirring, the molded glass is basically free of bubbles.

Glasses with bubbles are not only unsightly, difficult to promote in the middle and upper layers, but also prone to breakage.

Before, Jia Cong discussed with the ministers of the court and the central government in the Nancheng Liuli Factory, and most of them used the ancient method, but now, through the comparison of the different formulas of the ten crucible furnaces, each has its own advantages, and the effect of adding borax is better.

It turns out that the technical methods of the ancients were not all outdated.

The glass cellar on Ningrong Street was a great success, and the next thing was to promote and clean up the insiders and moles, but Jia Cong was not in a hurry, and before that, he gave a part to Ge Xuanli who was in charge of the Zunhua Iron Factory, and a part of it was handed over to the emperor.

Good things can't be treated badly to their own people, and some Jia Cong naturally gave a set to the girls and women in Daguanyuan, and finally gave it to the elders.

Lotus Champs, the west of the Grand View Garden, the open hall of the pool, facing the water on all sides, the left and right corridors, the shore across the water, the twists and turns of the bamboo bridge, the north and the Tubi Villa are far away, and the east is open to the Cave Jingxi Pavilion.

Jia Cong and they drank in a glass here, and everyone saw that the glass was crystal clear, and they all felt that it was full of freshness and had a different kind of beauty.

Xue Baochai's apricot eyes were in a trance: "We can indeed try to promote it in the official family, once it becomes a fashion, how can there be no money." ”

Jia Cong suddenly remembered those funny things in the Wei and Jin dynasties, "applying powder to He Lang", and the collective drug, and it was poison, which formed the Wei and Jin dynasties to a certain extent, although he was not poisonous, but the fashion was popular, and it was brought up by celebrities, literati and their officials since ancient times.

"Good wine, good glass." Shi Xiangyun sighed: "When I take it back to the two uncles to see, then they will believe me." ”

Jia Cong said: "If Sister Yun's family helps sell this product in the future, the reputation will always be better than arsenic vanamin." ”

Xue Baoqin, Sanchun, Li Kun, etc. all sighed, stunned and impressed by Jia Cong's invention and creation, of course, whether they can be sold and make a lot of money, this still needs to be tested by time and the market, and the most important thing is actually Jia Cong's subjective initiative, which has changed all this.

was playing and watching, Ying'er walked quickly to Jia Cong and Xue Baochai and said: "The Mei family came to discuss with Xue Erye, and the aunt said that it was not good to take care of it, but Cong Ye and grandma want to go back?" ”

Jia Cong Xue Baochai looked at Xue Baoqin's complexion, even if Xue Baoqin did not show much boredom and anger, but the slightly frowning brows and a little sad little eyes can make the couples who have experienced a lot of troubles in the world see that Xue Baoqin is at least not very satisfied with this kind of arranged marriage of his father.

She has traveled all over the three mountains and five mountains, overseas Zhuyi, if she is trapped in the boudoir in the second half of her life, it will be a tragedy, Jia Cong and Xue Baochai greeted each other and nodded, and they all agreed to go to the second room of the Xue family to have a look.
