Steamers and kettles, which are the closest contact with water, at a temperature of 0 degrees to 100 degrees, as long as they are not water, soaked or reacted, can be used as the material of the pot.

Ordinary cooking pots, can almost use iron sheets, but slightly thicker, in the era of no stir-frying, no coal stoves, the use rate of iron pans is not too high.

Among them, the most important thing is the earthen stove cauldron for cooking, which is also available, so you can't cut corners according to the iron sheet.

Because the earth pot is too large, the temperature may not be evenly balanced, and even if it can be avoided by adjustment, it must have enough thickness.

Big relationship, these pots can carry a lot of things, thin iron sheets, may be able to withstand a few catties of water, but the cauldron is absolutely not good.

It is precisely because it is not possible to study it, and forge it according to the previous one as it is, which is definitely not possible, that does not save much, for Zhao Xin and these researchers, any reduction, how much reduction is the key.

In this, there is a premise, it must be the same as the iron kettle, to ensure that it can be used normally.

Under the premise of normal use and certain durability, how much should be saved, how much weight should be used, and how much thickness should be used, so as to support the normal use of the entire iron pot.

Before, the problems that had never been considered were now placed in front of them one by one, but Niu Dali was very energetic.

In order to make these pots, Niu Dali spent energy, especially with Zhao Xin's help, Zhao Xin could not know how much to reduce, but Zhao Xin knew that the whole process of the experiment, with scientific experimental methods, reduced some unnecessary links, and even changed some shapes.

This is probably the biggest work of the research institute in recent times, mainly Niu Dali, divided into at least 20 different groups, building a large number of iron pots every day, each with a focus and difference.

After repeated experiments, he found the right proportion, and he really experienced the pleasure of experimentation, in order to reduce even the slightest thickness, the final cost will be greatly reduced.

For the iron pot that every family will use, reducing the cost also means reducing the expenditure and increasing the sales to a certain extent.

For the effect of the whole shape, he and his team cast at least 1,000 pots, which reluctantly made the current finished product, which is characterized as the No. 1 iron pot, is the most satisfactory product.

This finished product is very similar to the previous iron pot, but Niu Dali knows the difference, the appearance, the internal thickness, and the position and fixation, there will be differences.

This method is not without effect, it will reduce the weight of 20 catties compared with the previous iron pot, about half of the weight, in the application of heat, the processing of various ingredients, it also has a strong effect, this is the core competitiveness of the blacksmith workshop, with less iron, less raw materials, to make a pot with outstanding performance.

Of course, the iron pot is the top priority, and it is also the focus of Zhao Xin's introduction.

In fact, taking out things one by one, introducing the benefits of this thing one by one, Wang Song was already a little at a loss, and he knew that there were so many twists and turns in daily necessities.

When he heard that a huge iron pot was only one-third of the previous price, this was still the average price of the blacksmith workshop, if it was considered before, it was almost only more than one percent of the price, and even Wang Song was a little moved by such a price.

Iron pot as the only iron in most families, but also the most expensive property in the whole family, generally speaking, a small iron pot, at least need about 45 catties, according to the previous price, the price of an iron pot, as high as about 6.

Even if it is a blacksmith shop in the Daimyo Mansion, this cost is reduced, and the final price is about 3 times.

Now, the weight of an iron pot is about 20 catties, which is still very heavy, but the price of 40 wen per catty, the total cost of the iron pot, is only 800 wen.

For so many years, who has ever heard of such a cheap iron pot.

Wang Song here, there is no longer any doubt, Zhao Xinxin's actual situation proves his ability, just these iron pots, if they are launched, they can create tens of thousands of sales in the Daimyo Mansion, even if there is, it is not difficult to buy another one, the original five or six runs, now it is only 800 Wen.

Wang Song recognized the product, and the sales of civilian products in the future have improved, and Zhao Xin is also very satisfied.

The research institute he created was originally just to study some useful civilian products, and when Zhao Xin did not leave, he added a fist product to the blacksmith workshop, but he didn't expect that there was more Niu Dali as a researcher, as long as he understood the research process, he could bring forth the new.

A person who is very familiar with smelting and is willing to study it is hard to find.

To be honest, for the reduction of costs, at the very beginning, we should take such a way of cutting corners, which has also been proven by later generations.

In the early days of reform and opening up, the traditional state-owned enterprises produced products, are the kind of heavy, durable big guys, take the electric fan as an example, all are welded by angle iron or steel, the performance of the motor is also very good, the weight of an electric fan is more than ten catties, it may be used for decades, hundreds of years without damage.

Quality has become their foundation, but such a durable, excellent quality fan is easily broken by a small private fan.

The reason is very simple, reliability is not the biggest guarantee, small size, light weight, these are the advantages of these fans, but the biggest advantage is the price.

Price is always a big problem, the popularity of a product, performance is never the most important, the price is, although there are bizarre materials in later generations, but the most basic steel, and ordinary plastics, is the largest in the world, they represent the mainstream, of course, also represent cheap.

Cut corners, reduce the raw materials used in production as much as possible, or use some cheap materials, so that even if the performance is reduced, it can achieve the basic role, and on this basis, the price can be greatly reduced.

This is the easiest part to succeed and the best to succeed, but in the end, Zhao Xin did not choose this, because he was not familiar with it.

He knows that thin iron sheets can reduce costs, but how thin they are, he doesn't know how to make them, although he has a principle, there are not enough professional and technical personnel to help him achieve this, it is always short, but not as easy as the other aspect.

Co-ordination is one aspect, using higher efficiency, for example, saving the temperature of the furnace, making the hot sales higher, using coke instead of charcoal, reducing costs, which ultimately works wonders.

Even if Zhao Xin didn't know anything about smelting, he only relied on some concepts of later generations to put the key to the problem on the iron itself and industrial mass production, and reduced the overall cost by reducing the cost of raw materials themselves.

This is the most intuitive approach, and it is also a way to greatly enhance the strength of the Northern Song Dynasty, relying on the price reduced by half of the original, Zhao Xin successfully obtained the order of the Northern Song Dynasty government, and because of this, the price is the biggest advantage.

The cost of raw materials has been reduced from the initial seventy or eighty to 15 yuan, because of the continuous reduction, in fact, the cost of raw materials has been at a very extreme level, and there may be a certain amount of space, and this space is not big.

He thought that a lot of costs had been saved, and sales should increase greatly, but he found that after the price was reduced, the sales volume increased, but not so rapidly.

A little investigation will show that it turns out that from about 600 Wen to 300 Wen, or 200 Wen, it will stimulate part of the sales, but the sales of this part will not be too high, after all, at the level of the Northern Song Dynasty, ordinary people still have not much money on hand, and there are very few high wages like blacksmith workshops.

Even if you work on the dock all year round, it is about 1 time a month, a little more or less.

In this way, if there is a large family, the flexible spending is limited, and one person may save about 200 Wen, which may be used in some more critical places.

Zhao Xin had not studied co-ordination and business analysis, but in the very simple analysis, he was surprised to find that if the price was lowered on this basis, for example, to the previous one-tenth level, fifty or sixty yuan, or lower, it would attract people.

Cheap is the last word, in terms of cost, the reduction may not be high, even if a pound of iron is reduced to the level of seven or eight Wen, it is impossible to reduce a few to that extent.

When there is no industrial production, in the absence of large-scale steelmaking blast furnaces, it is not a question of whether it is difficult or not, it is a problem that cannot be achieved at all.

In this case, it was originally caught in a dead loop, and the current price is more competitive than before, but compared to the purchasing power of the people, it is too high.

The emergence of a large number of master craftsmen made him spend a lot of money to set up such a research institute, and now the results are born.

With Niu Dali as the main body, through unremitting efforts, just to provide a basic idea, these craftsmen, in which to innovate, out of at least 200 kinds of new products, these products without exception, on the basis of ensuring the original functionality, reduce the use of raw materials, a wide variety of products, almost all over all aspects, much wider than the original coverage.
