The sulfuric acid workshop and the glass workshop still have a bit of a factory, and the soda ash workshop is completely regressed to the realm of completely ignoring labor costs. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

After a ventilation accident that caused the eyes of two employees to be smoked by hydrochloric acid, Chen Jian set up a simple soda ash production workshop in the open space outside the workshop in order to expand production.

By hand, the hired hands carefully carried pottery filled with concentrated sulfuric acid like pickle jars to and fro; The pungent hydrogen chloride gas in the glazed pottery heating dish is discharged directly into the air; The soot roared to complete the calcination of sodium sulfate, lime and charcoal; The women filtered a black sodium carbonate liquid mixed with carbon black and calcium sulfide through gauze, heated and evaporated.

There is nothing to keep secret, as far as Mincheng is concerned, no one can learn, and if you learn it, you can't get sulfuric acid, which is completely different from the glass workshop.

The labor cost is relatively cheap under the law, so that Chen Jian is unscrupulous, and the output of soda ash has gradually increased from twenty or thirty catties at the beginning to four hundred catties a day.

The number of workshop workers also increased, and as transportation required an additional fifty adult hired workers, who were mainly responsible for transporting various raw materials from the county to the workshops.

Four hundred catties of soda ash per day is quite not low, which means that theoretically, the daily output of pure sulfuric acid is also nearly four hundred catties, and the large consumption of sulfur is gradually changed to pyrite, and the price is cheaper.

The amount of coal, lime, salt, etc. consumed is gradually increasing every day, and it is no longer a situation that no one knows about the coal bosses and mine bosses when the private factory was just established, and some mine owners have begun to take the initiative to come to Chen Jian in the hope of long-term cooperation.

There are also iron-making workshops that have come to Chen Jian because he bought a large amount of pyrite, and Chen Jian repeatedly said that he had no intention of doing raw wrought iron business, and bought it only to produce glass.

Talk to the owner of the iron-smelting workshop, the largest iron-smelting workshop in Nan'an, which produces only pig and wrought iron, with a coke blast furnace and a reverberatory stirring furnace to make wrought iron: after hundreds of years of development and specious scientific explanations, the production process of raw wrought iron is basically perfect in this era.

There are casting workshops in the iron-smelting workshops, but there are no forging workshops, and the wrought iron produced is sold directly and processed by the rest of the small blacksmiths' workshops.

The iron ore here is of good quality, and the coal is also suitable for coking, which is similar to the coal and iron ore near the old Yucheng in the north, which is a high-quality mine.

The iron-smelting workshops here are still very profitable, and some shipyards in Mincheng also need iron here as anchors, and it is said that some special charcoal smelting iron is refined and used to forge gun barrels.

For the time being, Chen Jian is really not interested in the iron smelting workshop, as far as the current technology is concerned, the level of iron production is already very high, and what is lacking is only steel, and the production of steel is still completed by small handicraft workshops.

Chen Jian said that he would never do raw wrought iron business, but he still pondered steel in his heart. Whether to make money or not is secondary, the key lies in the accumulation of technology. From qualified flintlock pistol steel reeds to various precision parts in marine clocks that cannot be made now but will definitely be rewarded in the future, which will not hesitate to be made in a hundred years, this requires crucible steel technology.

This technique sounds simple, but it is difficult to do, and it takes a lot of experience to do it. When it comes to technical reserves and the level of science and technology, it is completely possible to figure it out now.

This thing sounds lofty, a crucible and 1,600 degrees Celsius, but in fact, when this thing was made, it was not long before Western Europe made coke iron, and it was even more than a century away from something mysterious like a steam blower.

It's just that the material can only rely on the accumulation of experience, and it takes one or two hundred years to find out all kinds of special tool steel.

In this life, he is not ready to rebel, so there is no need to immediately make any magic weapons, Chen Jian knows that materials science takes time to accumulate, and he knows the direction of technology, so he has to invest money in it.

After sending off the owner of the iron-smelting workshop, Chen Jian calculated the remaining funds outside his turnover and did a few things.

First, he got a bill of exchange for 1,000 silver coins, wrote a letter to Lin Xi, who was far away in the capital, and asked her to hand over the letter to Mr. Mu from the School Palace.

The thousand silver coins were given as a reward, and it was hoped that Mr. Mu would make a great reward among the craftsmen of the capital with his reputation, starting with a balance that could weigh about a third of a gram.

The development of scales or scales, this group is backward, Chen Jian is hoping to make a balance that can weigh an accuracy of about one-thirtieth of a gram, this should not be able to be made for the time being, so the 10,000 silver coins he promised before cannot be used for the time being.

But there is no problem with one-third of the grams, and the right craftsman can completely get it out, first play the effect of a martingale standing wood, and then find a way to improve the accuracy.

The nautical clock incident of that year was also because of a huge amount of reward, a self-taught craftsman started with two hundred and fifty pounds sponsored by others, and spent a lifetime to make a complete set of precision tools, including various precision clock parts, crucible steel to minimize the effect of thermal expansion and contraction, rolling bearings, ......

In this regard, Chen Jian is sure that the gap between his two brushes is too big for today's craftsmen, so he can only rely on money to smash them.

The second thing was to ask Hu Lin to take the money and go to the best smelting and forging workshop in Mincheng, which could forge large pieces such as anchors and make small leaf springs, and find craftsmen there to make a kind of iron wheel.

This kind of wheel is required to be snapped into the convex groove of the wooden rail, the size and specifications are clearly written one by one, and there is no need for too good materials, cast iron or wrought iron can be.

The load capacity of human Ramallah is not too large, and the wooden one is actually fine, so this problem should not be big.

The third thing was to find the craftsmen who made the crucibles - their main business objects were the craftsmen who made the pots, and the craftsmen used the crucibles to smelt the molten iron. In addition to them, there are some craftsmen who can make crucibles, which may be more skilled, but they may all be in the industry of smelting lead, gold, silver, zinc, etc., and it is difficult to find them for a while.

The craftsman did not earn much, so he did not spend much, and he spent some money to make crucibles out of clay, china clay and graphite.

This Chen Jian can't do it himself, but this kind of craftsman can be made within half a year, and Chen Jian is convinced of this.

The fourth thing is that some furnaces have been built, but these furnaces are not used for production, but for experimentation and experience.

First, there was a smelting furnace with a high chimney, which was used to try to smelt some of the crucible steel when the graphite crucible was made.

Once the crucible steel was available, a watchmaker would be hired to help make a reasonable flintlock gun bolt.

Today's flintlock firing device has some problems, so the firing rate is not very high, and the steel is expensive, so mass production is not realistic.

To be precise, the current flintlock pistol still takes the road of friction and fire, not the way of impact fire, so the internal structure is still a little worse than the hammer device that was used in the past life to hit the fire.

Nowadays, there are no universal parts, it is unrealistic to change arquebuses to flintlock pistols, and there are basically no foreign enemies, Chen Jian feels that unless his home is an arsenal and there is collusion with the military figures above, it is unlikely that he will change clothes.

You had to first get a flintlock pistol with crucible steel as a hammer device, and then find a way to make a sleeved bayonet, and combine the two to find a new tactic on the front, even if it was to be used when you went to sea in the future.

It was not the flintlock pistol that eliminated the era of the arquebus, but the bayonet on the flintlock pistol, which led to the merging of hand-to-hand combat and projectile soldiers. Jian Chen knew this very well, so it was even more urgent, this was a weapon that his own group of outlaw crews must have before going to sea.

There is also a calciner, which is to try to burn cement by soil method, which does not require too good results, only needs to be able to build a strong and waterproof road surface.

This problem is not too big, clay and lime are calcined together with pulverized coal, crushed and gypsum.

How to ingredient, this is a problem that needs to be tried, try slowly and not afraid to throw money, you can always try it.

A supporting hydraulic mill is also following up, and this kind of cement is lumpy after calcination and needs to be crushed before it can be used.

The last attempt was made of cast iron and refractory brick closed furnaces for dry distillation of coal.

Dry distillation coal can produce coal tar, coke oven gas and crude ammonia, coal tar may be useful in the future, this can be kept, gas Chen Jian does not dare to use it for the time being, after all, the sealing can not be too good.

The main thing is to get crude ammonia and accumulate the technology of dry distillation coal.

There are only a few ways to make ammonia, and it is too difficult to make calcium cyanide with calcium carbide and then use calcium cyanide and nitrogen to make ammonia - there is no hope in life.

And synthetic ammonia, don't even think about it, it will take almost 200 years to speed up and connect the world together as soon as possible, but by the time science and technology develop to that point, the world war is estimated to have started: the historical line is completely messed up, the market is too small, the production capacity is too large, and no one is immune.

After thinking about it, there is only one way to make ammonia, and it is the only feasible method under these conditions.

To this end, Chen Jian went to the place with which he had worked with to produce many strange glazed pottery, and ordered a batch of even more strange clay pots.

The most important thing is a batch of jars used to hold ammonia, the mouth on the top is very small, and it is also very strong, which can be filled with ammonia.

In the last century, this thing was very common in the rural areas of some counties, and the products of the five small factories, as one of the few sources of nitrogen fertilizer before the 43 plan, were almost a guarantee for a certain period of time to increase grain production.

The gas after the dry distillation of coal is condensed through a pottery pipe to remove the coal tar, and the crude ammonia water rich in various impurities is packed into the jar, and then purified by heating or lime absorbing water and releasing heat when used.

This can be used to make a silver mirror, which is easy to explode, but the profit of a mirror is enough to compensate for a human life, and it is connected with a glass workshop, and it is a lucrative light industrial product.

There is glass, there is tin, there is hydrochloric acid, and it is always possible to make a sensitizer stannous chloride, and it is always possible to think of a way, and there is sulfuric acid and saltpeter co-heating, although the output of nitric acid is low, it is enough to make a mirror, and there is no glucose, maybe maltose can make do with it, after all, there are also aldehyde groups.

When these four things are done, it does not affect the normal production of the workshop, and it is experimental in nature, and the cost will not be too much.
