To make a mirror must first have glass, and glass has a long history, it is said that glass was first invented by the Phoenicians in Europe, so as to be the first popular in Europe, some people say that the Chinese nation in the Shang Dynasty has inadvertently obtained colorless glass, there are different opinions, anyway, the people at that time are dead, and no one witnesses, how to say it.

Yu Jin knew that the glass was regarded as a commodity and applied in Huaxia, and the most widely recognized was that during the Yongzheng period of the Qing Dynasty, a large number of Western novelties were imported, dedicated to the palace and appreciated by Yongzheng, so as to become a treasure sought after by the upper echelons of celebrities, so as to officially appear on the stage of Chinese life.

Now is the middle of the Ming Dynasty, during the Jiajing period, there is naturally no mirror, no glass, for this new thing, it has become the biggest business opportunity, the essence of doing business is nothing more than eight words: no one I have, people have my fine, Yu Jin does not want to fight with others to make connections, fight hard, then fight creativity.

The manufacture of glass is not difficult, the manufacturing process is not complicated, the material is very simple, mainly sand and limestone, quartz melted together to form, Yu Jin was the gold shop in the previous life, and he also had to do some chemical experiments such as gold plating and purification on weekdays, and he had a certain attainment in chemistry, and it can be said that there is no difficulty in operation.

The cost of making glass is very low, but Yu Jin knows that the profit is absolutely crazy, you know, the emperor also regarded it as a treasure back then, and people have commonality for aesthetics.

This violent needle girl really woke up the dreamer with a word, Yu Jin has racked his brains in order to do something business these days, and now it's okay, Wu Xuan scolded, and immediately had inspiration.

Just do it, Yu Jin will act immediately.

To make a mirror, you have to do the test first, find the best ratio of the right material and formula, and find out a set of practical processes, when making these things, there is a pungent smell, it is not suitable to do it at home, and it is not conducive to secrecy, Yu Jin gritted his teeth and spent fifteen taels to buy a single-family house on the outskirts of the city.

The house is a little dilapidated, there is only one hall and three rooms, with a kitchen, not even a thatched house, it is estimated that the original owner is a lazy person, go out of the house and find a grass to solve, but the victory is that the yard is big enough, with the area of the later generations to calculate more than 100 squares, this is the source of cheap land on the outskirts of the city.

There are no other people within a radius of three miles, so you don't have to worry about winning over others, and most importantly, there is a small river in front of the door, so you don't have to worry about the water source first.

After setting up the place for the experiment, Yu Jin quietly got a large number of materials and hoarded them, purchased iron pots and other things, and told Yu Lin to go out and read books quietly, so he plunged into the small mansion to study.

For the sake of secrecy, when buying materials, Yu Jin deliberately bought a lot of messy things, so as not to attract the peep of people who are interested after successfully making a lot of money.

"The quality of this sand is not good, it is estimated that the quartz content of the sand is insufficient"

"It's become so hard, it's because of the limestone."

"Well, not enough heat"

"There are too many impurities, and the purity is too low compared to the materials of later generations, so try to purify it."

Knowing the formula, Yu Jin worked hard for nearly a month, experienced countless failures, and the failed products were piled up in half a room, and finally got three good finished products.

It's not easy, looking at these three pieces of glass that are good in appearance and quality, Yu Jin smiled, although the quantity is not much, but this is also the first batch of high-quality glass independently manufactured in Huaxia, which has epoch-making significance, of course, this also represents a bright "money road".

Although these three pieces of glass are the first batch of products and are worth a lot of money, what is really valuable is the stack of materials on the desktop full of various experimental data, or this is a complete set of glass manufacturing process, which is the crystallization of a month's sweat.

Yu Jin picked up one of the pieces of glass and put it in front of his eyes to see, yes, crystal clear, there is a beauty similar to a gemstone, put it in the sun to see the seven-colored light, it looks very beautiful, this thing is estimated to be a defective product in later generations, but in the Ming Dynasty, it is definitely the existence of rare treasures.

At that time, it can be used as window glass, utensils, telescopes, etc., and there are many uses, which also shows that the wider the money, this time it will definitely make a fortune.

Of course, these are follow-up plans, Yu Jin understands the truth of Huaibi's guilt, and before he has the ability to protect himself, everything is better to be adjusted, so as not to be seen by others, and he doesn't know how to die at that time.

Fortunately, now that I have the identity of Jinyiwei's secret agent, let's slowly become bigger and stronger.

After making up his mind, Yu Jin no longer hesitated, and immediately made a mirror, this step is not difficult, that is, using tin amalgamation method, that is, using mercury to paste the tin foil behind the glass to form a reflection, which Yu Jin had already prepared, and it only took half a day to make three mirrors.

These three mirrors, the small one is the size of a palm, and the big one is about the size of an adult's face, all of which are small in area, but in ancient times, this was enough.

After the three mirrors were done, Yu Jin didn't take them for sale or test the water at the first time, because looking at some simple mirrors was not pleasing to the eye, and finally rubbed his hands and said to himself: "I haven't done it for a long time, just take these three to try it, and see how many percent of the previous craftsmanship is left?" ”

People rely on clothing, Buddha relies on gold, the commodity economy is inseparable from packaging, on this bare mirror is a little ugly, Yu Jin decided to package it, and then launch it grandly, from the perspective of economics, it is to increase its commercial added value as much as possible, so as to produce the maximum profit.

One does not do, two endlessly, Yu Jin decided to use a good packaging, in the previous life there is a craft to create gold and silver jewelry, the best is packaging, tailor-made for customers The only unique jewelry is also one of the important businesses, in addition to being a gold shop owner, Yu Jin still has a double identity: the number one jewelry master in the store.

I haven't done it for a long time, so let's think it's a practice.

If you want to pack, Yu Jin is a little difficult, it is difficult for a woman to cook without rice, and the craftsman also has to help with a good tool, the so-called sharp weapon is a tool, Yu Jin wants to use packaging jewelry like packaging these three freshly baked mirrors, but the tool can not be less, this is not to make furniture or repair the house, to do is to do fine work, many tools to be customized.

Such as a small hammer with horns, a carving knife, a rounded corner carving knife, a three-point knife, a five-point knife, an eight-point knife, a right-angle carving knife, a tweezer, a frustration knife, etc., Yu Jin turned around for two days, and visited all the blacksmith shops in Yuyao, but he couldn't make it up, most of them could only be specially customized, no way, Yu Jin had to draw the drawings one by one, and find those skilled old blacksmiths to explain clearly one by one and then let them build.

After calculating the cost, Yu Jin smiled bitterly, it took a month before and after, and more than half of the ninety taels of silver were spent, and a penny has not been earned, which is really miserable.

Mainly to buy a house, add furniture and raw materials, here has been nearly thirty taels, and then the biggest expense is to customize the tools, let the old blacksmith use the best materials, and the requirements are also very demanding, the average cost of a knife is as high as four cents of silver, Yu Jin in one breath on more than thirty, just here spent more than ten taels of silver.

The silver spends a lot, but Yu Jin does not regret it, if he wants to do a good job, he must use his tools, these are just investments, and he will definitely double his earnings at that time

On the way home, Yu Jin inadvertently looked at his appearance in the water, and he was stunned: it turned out that his fair skin was a little darker, and he was also emaciated.

Well, in terms of age, I'm still a developing teenager.

When he went home to eat, Yu Lin also noticed it, and kept picking vegetables from Yu Jin's bowl, and said with relief while coercing: "My son has been studying hard recently, and he has lost weight, come, eat more to make up, my mother will see if someone sells pheasants tomorrow, I heard that eating stewed pheasants is the most supplement." ”

Yu Yu raised her small mouth and said with some jealousy: "Mother, Yu'er has also lost weight." ”

"You little girl, can you be without you, come, this egg is for you." Yu Lin smiled and carried a large piece of egg into Yu Yu's bowl.

Yu Jin smiled slightly, took the largest piece of meat in the bowl into Yu Yu's bowl, scraped the tip of her little nose with his hand, and said with a pampering face: "Eat, after eating, my brother will take me to buy red bean cakes to eat." ”

"Thank you, mother, thank you, brother" Yu Yu, a snack goods, smiled like two crescent moons when he heard that there was food, and thanked him very obediently.

"You kid." Seeing that the brother and sister were so united and friendly, Yu Lin couldn't help but smile knowingly.
