Xiaotian pondered the glass as early as when he was on Lijiadao, and when he read the novel in his previous life, those who passed through the predecessors could always make the glass very easily, Xiaotian was envious, so he pondered it indiscriminately, and only created a lot of ugly and opaque defective products, which really can't be called glass, but then Xiaotian had a wit, this thing is still good as a tile, and it can also be reflective.

In this way, although this thing failed, the production and development have not been stagnant, and it has also brought a lot of profits to Xiaotian, until this year, the glass produced has barely been translucent, although there is still no use.

It wasn't until a few days ago that I established contact with the Portuguese, and the technology of glass manufacturing grew rapidly, and now, I am finally about to say goodbye to the tile business.

Sixteenth-century glass, both in Europe and in the Ming Dynasty, was a genuine luxury, and its use in this period was mainly as a cheap gemstone, with little utility.

Father-in-law Zhang grew up in Da Nei all his life, and only served as a supervisor a few times, so he was very curious about such a large factory, and while listening to Xiaotian's introduction, he visited left and right.

Xiao Tian from the later generations, he believes that the large factory production model has a small workshop can not be compared with the superiority, this factory he smashed in 400,000 taels of silver, in addition to the court itself, only he has this financial resources, but also only he has this courage, this era, the factory is a very new thing, including Europe, the mainstream is a small handicraft workshop.

In fact, Li Yan has always thought that this is a failed investment, 400,000 taels of silver, the factory has been put into operation for several months, but he has not earned a penny, on the contrary, he has lost a lot, although the price of ceramic tiles is also good, but the production cost of this year is really high, basically there is no profit, throw out the labor expenses, it is good to be able to mix a flat.

Seeing Xiaotian, a typical European with yellow hair and blue eyes in the lead strode out, and said in half-baked Chinese: "Oh, my dear boss, you are finally here, I have been waiting for you too hard, you must take a good look at my research results today."

Xiao Tian smiled and introduced: "Grandpa Zhang, this is Jack, one of the best glass craftsmen in Venice, because he offended the local nobles and followed the Portuguese to my Daming, and I have been working for me since I found out, and I have paid him a full salary of two thousand taels every year."

Father-in-law Zhang was taken aback and said, "Two thousand taels? This is higher than the governor of a province, why should a mere craftsman give so much silver? ”

Xiao Tian smiled: "Because of the value, I always believe that the value that technology can create is priceless."

After contact with the Portuguese, Xiaotian's glass factory can already make some transparent glass balls or translucent glass bottles, glass balls can be used as gems to deceive some nouveau riche who have not seen the market or something, glass bottles can be sold to rich people, in Xiaotian greatly encourages technological innovation and large factory assembly line cooperative production mode environment, they have invented the technology of carving on glass, transparency has also been greatly improved, and the products produced have even been sold to Southeast Asia, It was more than a section of glass in Europe. Even in the afterlife, it can be regarded as something that someone is willing to spend money to buy.

However, these two things make a little money and make a living, and when they open such a big factory, the profits that are lost are really shabby, because the profits created are too small, and Xiaotian doesn't even bother to take them.

This awkward situation didn't change until Jack joined.

Don't assume that every country in Europe can produce glass, especially fully transparent glass. During this period, only Venetian glass could achieve complete transparency, and they even invented mirrors, so Venice is also known as the City of Glass.

Of course, the salary of two thousand taels of silver cannot be to recruit a technician, Jack's work is somewhat similar to that of the chief engineer of later generations, the craftsmen of this period in Europe will never pass on their skills to others, this is their craft to support their families, when they first talked about it, Xiaotian gave him a full 20,000 taels, and this foreign devil promised to hand over the technology to every worker in the factory.

After Jack joined, the factory began to produce transparent glass in full force, and the yield rate was greatly improved, even if it was a failed product, it could be sold at a high price, and the factory suddenly became a super emerging on the island from a dispensable chicken rib.

Jack is so excited, has been looking for Xiaotian, of course, it is an experimental thing, Chinese have never been dumber than Europeans, more people have more power, after Jack pointed out the direction, countless scientific research talents emerged in the factory, and the glass produced became more and more transparent, larger and thinner, until a few days ago, real glass pieces were produced.

Of course, Jack is very excited to invite Xiaotian to take credit, with glass sheets, it means that mirrors can be produced. In this era, Venice has already invented mirrors, but the price is outrageous, Venice can only produce single-digit mirrors every year, and they are ordered out by the royal family and the church as soon as they come out, and there have even been several small wars in Europe in order to grab one or two mirrors.

Of course, Xiaotian was very happy to see the finished mirror, but he didn't play for a while, and he was a moth again.

In this era, the way Venetians made mirrors was mercury, which was actually very simple, covering mercury with a transparent glass plate, and relying on the reflectivity of mercury to reflect the human figure, so Jack "invented" the mirror in less than half a day after the glass plate was manufactured, and shamelessly asked Xiaotian to give him a salary increase.

But such a mirror naturally does not meet Xiaotian's requirements, first, this thing is poisonous, and the smell is very pungent. Second, this thing is not clear, and the figure that comes out is blurry. The third is the main reason, because this thing is too expensive.

The production cost of glass is not low, and mercury is even more expensive in this era, so Xiaotian put forward a new requirement, not to use mercury mirrors, and to develop silver-plated mirrors.

The silver-plated mirror is a modern mirror, Xiaotian has a friend who works in a glass factory, and knows that as long as a layer of silver nitrate and ammonia mixture is sprayed on the glass. Now there must be nowhere to find ammonia, but silver nitrate can still be found a lot from the Wa country, although this thing is not cheap now, but it is somewhat stronger than mercury, and the most important thing is that this thing only needs to be sprayed a little. And there are not as many drawbacks as mercury mirrors.

Xiao Tian doesn't know how to make a mirror without ammonia, but Xiao Tian knows that ammonia was invented after the silver mirror. So Xiaotian didn't care about it after providing a large amount of silver nitrate, you guys studied it yourself, and you had to plate it for me anyway, and it was plated with a salary increase.
