In addition to the master-apprentice method, the inheritance of the ancients also has a family tradition, in fact, the family tradition occupies a more important position in many aspects. Pen "Fun" Pavilion www.biquge.info

Shen Chong is deeply rooted in Shen Kuo's family heritage, including Shen Kuo's will, which is a traditional virtue, and it will not cause criticism if it continues to do so.

It's just that Gao Feng didn't want Shen Chong to continue to write "Mengxi Writings", although "Mengxi Writings" has natural science content, but its length accounts for more than 30% of the points, and it has more records of politics, military, folk customs and other aspects, so it seems miscellaneous and chaotic.

What Gao Feng wanted Shen Chong to do was to write a special book on natural science, so that it would be more targeted.

It's just that he can't say this kind of thing for the time being, who knows if Shen Chong is to uphold his father's will, or if he has greater ambitions, if he is wrong, it may backfire if Shen Chong's ancient bull temper comes up.

Gao Feng arranged for Shen Chong to enter the workshop, and naturally he would not reveal it to him in the early stage, he still needed a process of understanding Shen Chong, and if he was satisfied, he would let him know more.

After arranging Shen Chong, Gao Feng continued his chemical experiments, and finally, he made another convenient item, that is, matches.

The ancients used two wooden branches to rub against each other, and later used flint and steel, which was a troublesome method, and it took a long time to make a fire, sometimes half an hour to generate a fire.

Later, when he came to the Northern and Southern Dynasties, that is, in the ninth year of Emperor Chen Xuan's Taijian, there were wars in all directions, and the Northern Qi was attacked by the enemy, and there was a shortage of materials, especially the lack of fire, and cooking was a problem. At this time, the concubine and a group of palace maids came up with a method, they dipped sulfur on small wooden sticks, with the help of fire or fire knife flint, they could easily start the "yin fire" into "yang fire", this method is called the magic candle, and it is also regarded as the most primitive match.

This method is much more advanced than before, and the efficiency is much higher, so it was quickly promoted, and in the Song Dynasty, it was improved, when people used paper-thin pine chips, smeared a little sulfur on the top, and also ignited with the help of fire or fire knife flint, the effect was much better, this method was called candle at that time.

The development of ignition to this extent, the progress has been a leap, and later people invented the fire fold in order to facilitate carrying, which is considered a progress.

It's just that all of this is not perfect, whether it is a candle or a candle, it is not convenient to carry, the same, the efficiency of the fire can only be regarded as a relative improvement, but there is still a gap from the ideal.

The fire fold is a dark fire installed in the bamboo tube, and if you accidentally fall from the bamboo tube, the wind can become an open flame, and there are naturally unsafe factors. In addition, it is necessary to replace the ignition on a regular basis, which is very troublesome.

The matches made by Gao Feng are the safety matches of future generations.

This match is divided into two parts, one in a matchbox, the sides of which are coated with red phosphorus, diantimony trisulfide and glass powder; The other part is on the matchstick, the head of which is coated with potassium permanganate, manganese dioxide and sulfur.

When the two rub together, the heat generated ignites the red phosphorus in contact with potassium permanganate and causes the flammable material on the match head to burn, which sets the match stick on fire.

The technical difficulty of match making is not in other things, but red phosphorus.

To make red phosphorus, white phosphorus must first be used.

White phosphorus is easy to obtain, but white phosphorus has a low ignition point, sometimes it can spontaneously combust in the air, and it is also highly toxic, so white phosphorus is not suitable for making matches.

The principle of white phosphorus to make red phosphorus is very simple, that is, it will become red phosphorus when heated to more than 500 degrees, but it has a technical difficulty, that is, it isolates the air, otherwise, it will burn.

In order to isolate the air, Gao Feng thought of many ways, and finally made a vessel that could be vacuumed out of glass.

The emergence of safety matches immediately caused a sensation, it is not only easy to get angry, but also easy to carry, and its price is cheap, so it is all the rage.

To produce matches, the peak was divided into two parts, one part was to prepare the smear, which he handed over to the Gao family workshop, and the other part was hardware processing and combination packaging, which required more man-hours, and he handed it over to the county government, and finally sold it by the county government. As for profit sharing, the two are divided equally.

He is also selfish, and the technology cannot be fully announced, otherwise he will not be the county governor in the future, wouldn't he give others a big gift in vain? Besides, the Gao family's money is his money, and the county government's money is the money of the imperial court, and the two cannot be confused for him.

These are all legitimate means of the peak, and they are also a means of business. He had never been greedy. No matter how much money the county government has, it is also public, and he will not touch it privately, and all the money he spends is from the Gao family's workshop. As an official to his level, he is not moved at all in the face of millions of guan, and he has reached another realm.

Of course, it is impossible to say that there is no abuse of power for personal gain, whether it is the workshop of the county government or the workshop of the Gao family manor, he has the final say, how to arrange the weight, how to distribute the benefits, is not it his thoughts?

However, no one doubts about this kind of thing, everything is designed by him, without him, no one can do it, anyway, it can bring profits to the county government, and it can also facilitate the people's life, and no one will pour dirty water on him in one more move.

Gao Feng also knows the drawbacks, local officials, if there is no personal fraud, it is impossible, so the imperial court will restrict officials from being local officials, the reason why he can stay in the local area is because he has taken advantage of the development pilot of the county, as for the future will definitely be transferred here, once he gets there, he doesn't know how to deal with the affairs of the county government, after all, there are too many things involved in the Gao family manor now.

"Three years of Qing Governor's Mansion, 100,000 snowflakes of silver." Although Gao Feng did not take a single cent of bribes, nor did he take an extra cent from the county government, he used the power of the county government to vigorously develop the Gao family workshop, and the profit in the middle was more than 100,000 taels.

Fortunately, every thing he does, the county Cheng comes forward to negotiate with the Gao family workshop, and even the distribution of interests is led by the county Cheng, even if the contract is signed, it is also handled by the county Cheng, so that he can avoid relevant contradictions.

I have to say that Qiu Yi is still very competent, his fairness and selflessness are famous, and he also has some unique vision, so in the negotiations, he fights on the basis of reason, and has won a lot of interests for the county government.

However, these are all expected by Gao Feng, and he is happy to see the performance of hatred, which will no longer be an old-fashioned literati official in the future, but gradually evolve into an out-and-out businessman-minded person.

This kind of enmity is more suitable for entrusting important tasks, and officials who have no sense of interest can manage the water and soil of one side well?
