On the east bank of Ba Shui, more than ten miles upstream of Ba Kou, the sand dredging field lined up along the river bank is in full swing, and many sand dredgers carry a basket of river sand ashore, and then carry it to the hydraulic sand separator not far away to pile it up. Pen "Fun" Pavilion www.biquge.info

Each basket is exchanged for a bamboo chip, and these bamboo chips can be exchanged for money, that is, the wages for digging sand.

The sand separator keeps turning under the drive of the water wheel, and the river sand falling at the entrance is preliminarily screened, and the iron sand in the river sand is screened out, and then transported to the Huangzhou Ordnance Supervision Iron Smelting, cast into various weapons or agricultural tools.

The rest of the river sand is transported to the nearby glass kiln, and after the inconspicuous sand enters the kiln, it comes out with expensive glass.

Under an awning, Lu Yu looked at the sand digging field in front of him, and sighed secretly like other peers, sand turned out to be the raw material for making glass or glass, and no one could sit still if they knew.

But if you can't sit still, you have to sit, people use sand to burn glass, you draw a gourd and pour sand into the stove, and what is burned can only be garbage.

What's the problem? In terms of the recipe, sand is the main ingredient for firing glass, but you have to add something else, what are these things? I don't know.

If he knew, Lu Yu would have made a fortune eight years ago.

That year was the second year of the elephant, and the two sons of Yu Wenliang, the governor of Anzhou, came to Anlu from Chang'an, and his second son then began to sell glass jewelry and products in the city, which is said to have been purchased from merchants in the Western Regions.

Indeed, merchants in the Western Regions, such as the Sogdians, often sold glazed wares from Persia and Fulu in the far west, but where were the merchants of the Western Regions in Anlu? There are also a few Sogdian settlements in Jingzhou, so everyone is wondering where this Xiyang county prince buys the goods from, and Lu Yu is one of them.

He is a native of Anlu, and after careful observation, he found that the Duke of Xiyang had another courtyard by the Zhuanshui outside Anlu City, and seemed to be digging a lot of river sand, so after pondering for a few nights, Lu Yu also went to the Zhuanshui to dig river sand.

The river sand drained the muddy water, dried and put it in the urn to burn with fire, but it didn't burn for a long time, and the pottery urn didn't seem to work, so he used the copper urn, and the bottom of the copper urn was soft or not.

It seems that you have to add something else, Lu has tried a lot of formulas, but the effect is not ideal, of course, he has occasionally burned small pieces of colored "suspected glass", but it has no use value at all, so in the end he can only give up.

He figured it out, Xiyang Jungong must have a recipe in his hand, so he can use river sand to burn glass, but the formula is very complicated, if ordinary people want to try it, unless it is a coincidence, it is difficult to try it.

Not to mention the magical glass mirror, how many people organized craftsmen to explore, but they couldn't figure out the production process of the glass mirror.

If it is a weekday, there must be someone who can't bear it, and wants to "ask" relevant people and so on to "ask" relevant secrets, but the identity of the prince of Xiyang County is sensitive, and no one dares to make up his mind, so in the past eight years, everyone can only helplessly watch Yuwenwen make money.

It's still the same now, the glass workshop doesn't care about others seeing them mining sand, and directly lets the merchants who come to order see a basket of sand transported into the kiln, this behavior is to show off: what if you see it? Without a recipe, don't even think about it!

A group of merchants in the shed have helpless expressions, and they have also figured out the key, river sand is the main raw material for firing glass, but they can't burn it themselves, so the formula is the key.

The king of Xiyang paid tribute to the Son of Heaven glass, and the news had spread when the convoy set off, and the glass floor-to-ceiling windows displayed by the shops in Xiyang City made merchants from all over Shannan come to hear the wind.

Glass windows were installed in the palace, as well as in the prime minister's palace, and the imperial court was very tolerant of glass windows, allowing private use, as long as a single glass piece did not exceed the specified size.

From the convoy loaded with glass to Yecheng, and then merchants from all over the country went to Xiyang, to Yecheng came to the news, it happened that everyone was in Xiyang, and the glass workshop just burned a lot of glass.

In just over a month, everything could not be more coincidental, and the intention of King Xiyang could not be more obvious: to make a lot of money with glass.

Many people are annoyed: why weren't they the ones chosen by the King of Xiyang?

The secret of glass, now in addition to the king of Xiyang, only the official kiln of Huangzhou and a few private kilns master, the idea of the official kiln no one dares to fight, and the private kiln, I am afraid that it is enough to choke, because according to some rumors, the owners of those glass workshops have spent a lot of money to get the formula from the king of Xiyang.

There are different opinions about how many people spent tens of thousands, or 100,000 yuan, but no one thinks the price is expensive, because what they have seen with their own eyes now makes them want to spend a lot of money to buy the formula.

In the open space outside the pergola, there are dense wooden boxes, and the merchants who have arrived in line lead their entourage to order the goods, and the pieces of glass are carefully inspected by them, and then carefully packed into boxes, and then carried to the dock by the side of the water to load the ship.

Cargo ships laden with glass went down the river, entered the Yangtze River through Bakou, and then went upstream, either to Anlu through Zhukou, or from Hankou to Hanshui, to Xiangyang, Jingzhou Suicheng or to Jiangling of Liangguo.

Merchants take the fluttering circulation coupons, buy a large amount of glass and transport it back, and the change of hands is to double the profit, so they are not afraid of high prices, but they are afraid that the output will not come up.

There are many rumors from the outside world that there are many untruths, the price of glass is indeed expensive, but it is still within the affordability of the rich, and the output is also very large, although there are many merchants who rush to buy, but it is not as exaggerated as the so-called orders are lined up for months.

Because the glass workshops in Huangzhou are ready, each workshop has at least four or more large glass kilns, and although their output is tight, it can barely cope with the current demand.

Lu Yu looked at the mountains of wooden boxes piled up on the open space and the busy scene on the dock, and roughly estimated the daily sales of this glass workshop, and then sighed, feeling extremely helpless.

The owner of this workshop, even if he spends 200,000 yuan to buy the formula from Xiyang Wang, according to today's shipments, I am afraid that it will not be able to return to the cost in a few months.

So the owner of the workshop is full of food, will leak the glass formula?

According to what the King of Xiyang said to the imperial court, at present, only the boundary of Huangzhou can burn transparent glass, and no one really believes it, but since the imperial court has the official kiln of Huangzhou to pay tribute to the glass, it will not be too entangled in what the formula of the glass is, so it is even more difficult for others to ask the secret from the mouth of the King of Xiyang.

Xiyang King actually turned the transparent glass into a Huangzhou specialty, which is really emotional, although I don't know the formula, but since there is a sale, then everyone still honestly line up to buy it, the more you enter, the more you earn.

"Look, look, it's Hu Shang!"

Someone whispered, pointing in one direction, Lu Yu looked in the direction and found that there was a large convoy of boxes there, and several high-eyed and deep-nosed Hu people were talking to people.

"Is it the Sogdian Hushang? They've come here to stock too? The news is really well-informed. ”

"How can they not be well-informed, the old business is about to turn yellow when they see it, can they not be in a hurry? Hey. ”

Someone laughed and said, "How do you say this?" ”

"Don't you know? In the past hundreds of years, the Sogdian Hu merchants have trafficked all kinds of exotic treasures from the Western Regions to the Central Plains, and one of them is not all kinds of glazed artifacts? Isn't this the old deal? What now? ”

"It is said that the king of Xiyang presented a five-color glazed formula to the imperial court, and the official kiln over there in Yecheng has begun to test burn, and Yecheng can also make a large number of colored glazed objects in the future.

"Hey, King Xiyang, this is really digging the corner of the Sogdian Hu merchants!"
