Wuzhuang Guan, in a small courtyard room, there are many rows of colorful glassware on the window shelf, there are glass bowls, glass tea cups, glass kettles, etc., some are made of transparent glass, and some are made of colored glass. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Xiyang Wang Yuwen Wenwen looked at the display in front of him with satisfaction, and Liu Yang, the master of Wuzhuang beside him, was introducing his masterpiece with high spirits, of course, he was responsible for the process of coloring the glass.

In fact, it is a snake painting, Yu Wenwen's glass (glaze) workshop originally had such an ability, but it was tried by the continuous experimentation of exhaustive methods, and Liu Yang used the "way of chemistry" to study it.

By "melting" different metals into the glass, the glass can be "colored", and the Taoist priests of Wuzhuang Temple have made breakthroughs in the research of a variety of "colored" metals, so Liu Yang is now showing the research results to Yuwenwen.

Nonsense, as the big owner behind Wuzhuang Guan, Yu Wenwen has invested heavily in helping Liu Yang research the "way of chemistry" for many years.

"King, the beamsplitter has been changed many times, and the spectrum of some metals has gradually become clearer, so there are more and more ways to color glass."

"In the boundaries of the Huangzhou Governor's Mansion, among the mines that have been mined, some useful ores have been preliminarily identified, which are enough for glass workshops..."

Yu Wenwen sat on the couch and motioned for Liu Yang to sit opposite, now it is private time, so he doesn't plan to put on a pomp and talk about humility, holding a thick summary report in his hand, he asked with interest while reading.

The so-called "spectral analysis" of Wuzhuang Guan is still very primitive, after all, without the backing of profound scientific theories, there is no way to further develop it, but it is already commendable that Liu Yang, the former alchemy madman, can do this step now.

Barely able to distinguish the high and low levels of certain metal components in various ores, which has helped Yu Wenwen a lot, especially in the glass industry, if he wants to make transparent glass in large quantities for a long time, he has to rely on the power of science.

The so-called transparent glass, of course, still has a color, based on high school chemistry knowledge, Yu Wenwen knows that as long as the glass contains iron, then it is inevitable to appear green, which is also one of the characteristics of ordinary transparent glass in that era.

He needed to make the glass as colorless as possible, so that he could find another way to make money, because in this era, glass products are actually very common.

The so-called common, refers to the rich and noble families are very common, and the impression of ordinary people in later generations is different, glass appeared in the Central Plains is actually very early, later archaeological discoveries, the tombs of the Warring States period have glass products, many are from the Western Regions.

The reason why I say this is because foreign glass is mainly soda-lime glass, and the original glass of the Central Plains is lead barium glass, archaeological findings, the glass products in the tombs of the Warring States period, the later the proportion of lead barium glass, what does this mean?

It shows that in this era, the Central Plains was already able to fire glass, plus the glass products sold by merchants from the Western Regions, so glass was not an extremely rare item for the Central Plains, but a common luxury.

Therefore, many people often use glass products as burials after death, and most of these glass products come from the Western Regions, of course, there are also glass products produced in the Central Plains.

In this era, the name of glass products is "glaze", and there are such as Xuanlin, Liuli, Langxuan, Yaoyu, Luli, Yuyu, etc., and the title of "glass" probably did not appear until the Song and Song dynasties.

For hundreds of years, the Sogdians, who had been engaged in business for generations, have been trafficking stained glass products from Persia and Rome in the far west to the Central Plains.

The glass mirror is an exception, but Yu Wenwen wants to do other articles on glass, and he has to analyze the "consumer demand" of the market and the "consumption psychology" of consumers before taking action.

The results were analyzed and analyzed, and it was found that the reason why everyone likes glass (glaze) products is mainly because they want to use them as a substitute for jade, followed by the good quality of glass (glaze) products in the Western Regions.

The jade culture of the Central Plains has a long history, and the glass products of the Western Regions have become a popular object because they look like jade, so Yu Wenwen summed up a very cruel fact from it: the sales of transparent glass products may not be as good as he imagined.

For example, glass (glaze) bowls, the reason why people buy them is that they think this thing is like a jade bowl, and it is particularly face-saving to put it out, which is the most important thing, and other reasons have to stand aside.

Especially in those areas where jade is not produced, glass products are very popular, and buyers use them as a substitute for jade, so you make a transparent glass bowl and sell it, how can people pretend to be forced?

Don't talk about any crystal bowls, what people want is to look like a jade bowl, just like the copycat mobile phones of later generations, that is, to look like an Apple mobile phone, where will there be a market for you to make a deformed copycat machine with eight speakers.

It is for this reason that over the years, Yuwenwen's glass workshop has been launching glass products, all of which are colorful and look like jade, and all kinds of high-end atmosphere are of high grade.

But Yu Wenwen was not satisfied, the transparent glassware was not forced for the rich, so he tried to make the glass have a forced style, so the glass window should be played.

There are two technical difficulties: transparent, large-size flat plates. These two points are the threshold, which can overshadow competitors, and the formula and process that Yuwenwen burned money to burn, as long as it is not leaked, it is not possible to try it in the short term by relying on the exhaustive method.

The firing principle of glass is very simple, silica melts to form a glass state, but the melting point of silica is more than 1,500 degrees, and there is no way to effectively melt in this era, so it is necessary to add flux and mix with silica to greatly reduce its melting point.

The various metal components in the co-solvent must be controlled in order to fire transparent and colorless glass, which requires basic scientific knowledge to be purposefully produced on a large scale.

And how to make smooth as a mirror flat glass, is another problem, Yu Wenwen has already solved it, using the tin liquid surface float method, but the process he transferred is a level lower, whether it is an official kiln or a private kiln.

The transparent glass formula adapted to the Bashui river sand, coupled with the process of making small-sized flat glass from iron plates, has a preferential price of 130,000 yuan, and the top three bidders are eligible to buy.

Transparent glass, Yuwenwen can be produced in small batches a few years ago, but if you want to produce capacity on a large scale at low cost, you have to find another way, and the process of achieving it is also very simple: add zinc oxide.

The smelting technology of this era could not smelt zinc metal in large quantities, but Yuwenwen could, after continuous experiments, found that zinc oxide as a strong flux, can effectively reduce the melting point of quartz, but also enhance the transparency of glass.

So after the fake gold, Yu Wenwen found another use of zinc, which can also make a lot of money, and this ingredient has to rely on his exclusive supply.

The dosage and proportion of zinc oxide are "optimized" for the river sand with high iron content in Ba Shui, and this formula is used in other river sands, and the fired glass will be turbid and look more like jade.

Knowledge is power, Yu Wenwen used a little trick to make transparent glass into a "Huangzhou specialty", and it must be burned out with Bashui River sand, which directly broke the idea of other places.

This kind of transparent glass is not used to replace jade, but to make tall floor-to-ceiling glass windows, which led the first tribute to the emperor and turned it into a tribute, which directly improved the quality and made countless rich and noble families have a strong desire to buy.

The glass output of the official kiln in Huangzhou is enough to pay tribute every year, and the output of the kiln is used to make money.

"The King?"

"Huh? Yes... Ahahahaha, Daochang Liu's report is well written, not bad! ”

The owner was in a good mood, Liu Yang felt that the opportunity had come, he considered the words, plucked up the courage to say: "King, Poor Dao has an idea..."

"What thoughts? Let's hear it, the widow has always been a strong supporter of the way of chemistry! ”

"Well, when Poor Dao was sorting out the collected Dan Fang, he found a Dan Fang that was quite interesting..."Liu Yang suddenly looked forward to Ai Ai, Yuwen Wen couldn't help but laugh when he saw this: "What is the content of the Dan Fang?" ”

"I wonder if the king knows about stone galls?"

"Daoist Liu, please get to the point."

"Ahem, this Dan recipe is called 'Stone Refining Gall Extraction Essence Method', and the obtained thing is called alum oil."

"Alum oil?" Yu Wenwen felt that the term was very unfamiliar, probably some kind of liquid chemical, but he was not interested in this thing, interested in why Liu Yang was hesitant.

Green? Could it be a beauty product? Sneaky, is it possible that it costs a lot of money to study this thing? Or is there some ulterior secret?

Used to make Dianabol? Rejuvenation pill? Soul Resurrection Pill? Or is it a mystery pill?

Thinking of this, Yu Wenwen was suddenly shocked: Wait a minute, you won't be studying what kind of medicine is Chunna!

My heart was pounding, and a huge feeling of joy came to my heart: there are so many rich but "incompetent" men in the world, this thing really wants to be made, I can't think of it without getting rich!

Daochang Liu, this green... If you are interested in any oil, you can study it, and how can you help? Yu Wenwen began to pretend, after all, it was too vulgar to ask about the use as soon as he came up.

"King, Poor Dao has been studying for a long time, and found that the concentration of this alum oil is still too low, and I have figured out several sets of methods with all my fellow Daoists, and I want to concentrate... Hey. Liu Yang was a little embarrassed when he said this.

"Don't you have enough money?"

"No, no, no, Poor Dao and all fellow Daoists have studied it for several years, and I feel that we need to find another way and make some special containers to effectively condense it."

Yuwen Wen glanced at Liu Yang, and laughed at the feeling of pain in his flesh: "Are these containers made of gold and silver?" No problem! ”

"No, no, no, the king, poor Dao and fellow Daoists think that it will be better to use lead, of course, the amount of lead consumed is not a small amount..."
