After the prosperous Tang Dynasty

Hearing Xiao Yansui's footsteps, the beagle, who was running back and forth just now, slammed on the brakes, turned its head and wagged its tail, and came towards Xiao Yansui like a swoop.

With its current size, Xiao Yansui can no longer hold it up, but the beagle still seems to be engrossed in Xiao Yansui's lap when he first scratched his chin, squinting his eyes and snoozing comfortably. In his memories, he flew to Xiao Yansui's side with an exceptionally vigorous figure, and immediately rubbed against her arms vigorously.

Xiao Yansui squatted down, hugged the neck of the beagle that was rubbing against her body, and patted its head lightly.During the movement, the other three aborigine dogs, who were so tired from running around with the beagle and lying on the ground, followed, and circled around Xiao Yansui affectionately.

After Xiao Yansui rubbed each of the four fluffy dogs twice, she suddenly felt that maybe she should get another shepherd dog—the kind specially used to watch the four of them walk the dog by themselves .

After finally begging the four enthusiastic furries, Xiao Yansui didn't even enter the study room, greeted Axiu, asked her to help prepare her clothes, and went directly to take a shower.

After Xiao Yansui changed into clean and light clothes, barefooted in slippers and letting loose some wet long hair, he took a look at the sky, stretched his body lazily, and then, at Axiu's hesitation to speak, Stopping, raised his eyebrows, and asked directly: "Axiu, what's the matter?"

Axiu immediately replied in a soft voice: "The sheriff of Nanlanling County just sent an invitation card, saying that it will be the beginning of next month for my daughter's wedding ceremony."

After hearing this, Xiao Yansui blinked her eyes, and her first reaction was, "Do I know her?"

Not long ago, Xiao Yansui and his grandfather Xiao Song met the local sheriff, but she was completely unfamiliar with the youngest daughter of the sheriff's family.

It's just that, although the sheriff is a local parental official, the ancestral home of the Xiao family in Lanling is here. Over the hundreds of years, in this small Xiao family village, how many people have been born one after another? The big shots, those officials who are the county guards here, mostly only went to work for a few years after receiving the edict. Compared with the Lanling Xiao family, which has been rooted in the local area for hundreds of years and has deep roots and leaves, it seems that the foundation is a bit shallow. Naturally, it is unavoidable to have a lot of handovers with the Lanling Xiao family, who is actually a local snake.

At the beginning, to show respect and importance to Xiao Song, after learning that Xiao Song was going home to retire, the sheriff of Nanlanling County came to visit in person. Now, even if it is to reciprocate...

Thinking of this, Xiao Yansui turned around to Axiu and said, "Have you talked to Ah Weng about this? Reply first, and then prepare a gift. I will go there in person when the time comes."

Axiu nodded, but she looked at the clothes and hesitated to speak.

Seeing it, Xiao Yansui was naturally suspicious, and asked directly: "Why such an expression, is there anything else?"

Axiu's lips moved, and she finally explained in a low voice, somewhat at a loss: "The servant girl thought about Liu Niang's ceremony..."

The Jiji ceremony in the Tang Dynasty is actually a woman's coming-of-age ceremony, and its importance is self-evident.For aristocratic families who are very particular about these etiquettes, the most important things in a woman's life are almost the ceremony and wedding...

The wedding still needs a man, but Jiji ceremony is completely the home of girls. Although the elders in the family will appear regardless of gender, for a girl, the company and blessings of mother, grandmother, and other female elders, In fact, it is also quite important.

Xiao Yansui listened to Axiu's words, but was a little taken aback before realizing that this winter was her 15th birthday.And if Xiao Yansui hadn't returned to Chang'an City before the end of the year, only Xiao Song, an elder, might be present for her Jiji ceremony...

However, for Xiao Yansui, the concept of adulthood is deeply rooted at the age of [-]. She has lived in ancient times for more than ten years, and she regards every bit of daily life here as customs. Laws are different, and you can follow them or ignore them. In other words, even if she already knows a lot of cognitions in Xiao Yansui's mind, they have never been turned into the Tang Dynasty pattern at all...

Standing there and thinking for a while, Xiao Yansui nodded, and said "Yeah", indicating that he knew, and didn't take it seriously at all, and turned around to go to the study.

Axiu was stunned, subconsciously took a step forward, and asked again and again: "Liu Niang?"

Xiao Yansui stopped in her tracks when she called out, and immediately waved her hands, "It's okay, it's just me and my grandfather here, I don't know the other guests well, and things like Ji etiquette, let's keep everything simple!"

--Just celebrate her 15th birthday with her grandfather Xiao Song, leisurely!

In fact, if you think about it carefully, if there is really a grand wedding ceremony held in Chang'an City, Xu Guogong's wife, Mrs. He, as Xiao Yansui's grandmother, will definitely appear.As long as he thinks of He Shi's tight lips, Xiao Yansui will feel bored.

Although she herself doesn't pay much attention to the Jiji ceremony, it is still a birthday with many guests. At this time, she can still see He Shi's face, and then she has to wait for He Shi's unwilling birthday wishes. Yan Sui even felt that He Shi might be cursing himself silently in his heart.

Thinking about the embarrassing scene, Xiao Yansui couldn't help twitching the corners of her mouth. Why did she really have to make things difficult for each other? She didn't have enough to eat...

Xiao Yansui's attitude was firm, but Axiu couldn't help it, and she couldn't help showing a bit of helpless resentment on her face.

After all, although a woman's ceremony is important, Xiao Yansui doesn't take it seriously, and Axiu always listens to her. Although she feels it's inappropriate, after getting the order, she can only hold back.

However, what Xiao Yansui didn't know was that whether it was her grandfather Xiao Song who brought her back to her hometown, or her parents and elder brother who were still far away in Chang'an City, they were actually still thinking about her Jili in their hearts.

Abandoning Axiu who was still standing there still feeling annoyed, Xiao Yansui turned around and went directly into the study, picked up a pen and paper, and began to recall some details about high-strength cement, and then wrote it down on the paper piecemeal As a draft, after sorting out the thoughts, I re-transcribed these precautions one by one and categorized into another paper.

As for glass, in fact, the Tang Dynasty already had finished products at this moment, and some specialized craftsmen had a very high level of glass blowing technology.

However, the glassware at this time completely inherited the craftsmanship and aesthetics of the Sui Dynasty. Basically, there are only two types of high-lead glass and alkali glass. From the appearance point of view, the state of this ancient glass is actually similar to that used for Glass, which is a building material, is relatively similar, but it is quite different from the lustrous and transparent silicate glass of later generations.

Therefore, glass in the Tang Dynasty was mainly used as exquisitely crafted utensils and relatively expensive jewelry. The limitations brought about by such a cost made there still be a gap between the glass and the real civilian use. .

After roughly smoothing out the high-strength cement material, Xiao Yansui put down his pen, moved his wrist slightly, and a strand of hair hung down from his ear. After touching it, he found that the hair was still a little wet before. I'm almost done.

Xiao Yansui simply got up, touched the ribbon casually in the study, and tied her hair loosely behind her head so that the loose hair would not fall on the paper and affect her writing—even if she used The pen is an improved pen, but the ink on the table is not fake. If you accidentally brush the end of your hair into the ink, it will be black and it is not obvious. It's not bad enough when the clothes are on.

After tying up her hair quite casually, Xiao Yansui walked slowly around the study room twice on her slippers. After moving her body a little, she sat in front of the table again and wrote down the previously copied text about high-strength cement. The materials were put aside, and then began to silently write the manufacturing process of the most common ordinary quartz glass in later generations.

The raw materials for making glass, even in the Tang Dynasty, were actually very easy to find, basically soda ash, limestone and quartz.

As for the composition of the final quartz glass, it is almost a melt of sodium silicate, calcium silicate and silicon dioxide mixed together in a ratio of 1:1:4.

Writing the familiar chemical formulas, Xiao Yansui felt extremely relaxed, thinking that after making the glass, in addition to installing all the windows in the house to improve the lighting level, in fact, those who are good at blowing glass can also let those who are good at blowing glass The craftsman helped her get a bunch of the most commonly used test tubes, beakers, stirring rods, Erlenmeyer flasks, U-shaped tubes, long-necked funnels, and various droppers in the laboratory that she missed for a long time. Xiao Yan became more energetic in an instant Sui couldn't help but wanted to whistle twice to express his leisurely and happy mood at this time.

After writing down the principle of the chemical equation for making glass, looking at those letters and symbols, Xiao Yansui couldn't hold back his excitement at the moment, so he simply put aside the experimental plan for the time being, and took another piece of paper instead. , began to draw the shape design drawings of common laboratory equipment with ease, and marked the detailed size parameters on it.

Xiao Yansui didn't put down his pen until he finished drawing all the glass instruments commonly used in the laboratory, and carefully looked at the equipment he was going to let craftsmen blow out of glass before drying the ink. , put it in the box for the time being, and plan to start making other shapes of glass equipment after the flat glass can be stably processed in the workshop!

Xiao Yansui, who had not yet passed the excitement, sat at the table and began to sort out the direct ingredients needed to make glass raw materials—no way, although the raw materials are actually soda ash, limestone and quartz, but in the actual production process However, only these are far from enough. At the very least, quartz should be concreted into quartz sand and an appropriate amount of feldspar. Needless to say, limestone, the most basic, in addition, there are soda ash, boric acid and other substances.

Moreover, all the raw materials must be weighed at a fixed ratio and then mixed evenly. As for the fixed ratio, depending on the impurities of the raw materials, she needs to do experiments to determine it...
