Occupy the pit...... I'm dizzy with a cold, my IQ has dropped a lot, I can't hold it back, take advantage of the pit for a while, and change it back in 20 minutes, sorry......

At present, there was no professional decontamination soap in the Ming Dynasty, and ordinary people generally used soap horns. Wealthy families, on the other hand, mainly use pig pancreas soap made from pig pancreas. The effect is okay, but not as strong as soap. Moreover, pig pancreatic soap is not cheap, and it costs more than a dozen yuan for one.

This is also something that can't be helped, in the Ming Dynasty, pork is not a bargain, as high as more than 20 wen a catty. In the future, it is equivalent to more than 20 yuan a catty, which is more expensive than beef and mutton.

Of course, this is in the north. Because there are many cattle and sheep in the north, the border army also secretly smuggles beef and mutton from the grassland, so beef and mutton are much cheaper. In the south, lamb is still relatively expensive. As for beef, it is almost impossible to find. After all, the Ming Dynasty government was not allowed to kill cattle without permission. And the cattle that die of old age and sickness are basically not of good meat quality, and they can't catch up with the delicious pork.

The most important thing is that pork has oil and water! The thirst for oil and water in ancient times is incomprehensible to modern people, because vegetable oil was lacking in ancient times, so oil and water were often only obtained from meat. And pork is obviously the product with the highest fat rate, and it is also the commodity that people like to consume the most oil. So, in ancient times, the fat of pigs was the favorite of people. Therefore, the ancients called very tempting things "big fat", not big lean meat. Even in the last century, the Chinese people were very short of oil and water. Many elderly people also have the habit of eating fatty meat. Just like Marin's grandparents in his previous life, they always like to eat fatty meat when they eat meat, and give lean meat to Marin. At first, Marin thought that they were completely lying to themselves that they "like to eat fatty meat", but in the end, they really didn't lie to themselves completely......

After traveling to this era, it was not only the ancient Chinese who liked fatty meat, but also the Europeans. Especially those who are poor, their eyes can light up when they see fat.

For example, the braised pork supplied in the army, the first to be robbed is often fatty meat. Only the children of the aristocracy are tired of eating fatty meat, so they often like to eat lean meat. Or, fat and thin. Only a traverser like Marin, as well as members of the royal family and big nobles, who can eat meat until they vomit, will like to eat lean meat. Many small aristocrats prefer to eat fatty meat.

Of course, this changed after Marlin introduced soybeans. Marlin uses a spiral oil press to extract soybean oil from soybeans produced in North America. Today, the nobility of the Beihai Kingdom, including many low-ranking officer families, have begun to consume soybean oil generally. Therefore, the dependence on fatty meat is greatly reduced. After all, stir-frying vegetables with soybean oil also has a lot of oil and water.

Just like the people of later generations to lose weight, you say you eat vegetables, why do you put so much vegetable oil in Nima to stir-fry vegetables? Vegetable oil is not oil, right? Eating such oily vegetables has a hairy weight loss effect? The really ruthless people eat boiled vegetables. That taste, I want to vomit after eating it a few times...... Therefore, generally only ruthless people can complete the feat of losing weight, and ordinary people can only say "concubines can't do it"......

Therefore, in ancient times, the biggest problem in making soap was not caustic soda, but grease!

In his last life, Marin saw some people who said that they used sesame oil to make soap, and they longed for a while. But when he came to this era and learned about prices, he knew how nonsense it was. Why? Because sesame oil is more expensive than pork!

People like to eat pork, but they like the fat in it. And sesame oil, it's all oil! Through Kong Tai's understanding of Daming, Ma Lin learned that sesame oil was not a must-have for ordinary people at all in ancient times.

Especially poor families, they can often only cook gruel, and it is difficult to afford sesame oil at all. Only during the New Year's festival will I get some oil and cut some pork. This is still not too poor, the really poor, there is no oil and water during the New Year's holidays.

Sesame oil, I'm afraid only the landlord's family can eat it every day. In addition, the monks of the temple can also mix. Therefore, don't look at the monk's vegetarian diet, people put a lot of sesame oil in vegetarian dishes. I eat too much of this kind of food, and I meditate every day like an otaku, and it's strange that the monk is not fat.

According to the data given by Kong Tai, in the Quanzhou area of the Ming Dynasty, pork was 24 Wen a catty. And sesame oil, actually reached 45 wen a catty, which is almost twice as much as pork!

With such an expensive price, Nima traverser uses sesame oil to make soap? I'm afraid I'm going to lose my pants, right? After all, there are only a dozen pieces of pig pancreatic soap for people's use. Do you use sesame oil to make soap? The cost is more than a dozen yuan, and you can still make a lot of money?

It's okay to make soap and sell it for a tael of silver, but don't do it for the mass type. If you dare to sell it more expensive than pig pancreatic soap, the people of Daming will definitely not buy it. For people in the poor era, quality is not what they value, price is!

Therefore, the elderly who came from the poor era, they will only sell bargains, and they will queue up when they hear about discounts. Only modern young people who have never suffered will pay attention to what quality and brand.

If you use the ideas of modern loser youth to do the business of ordinary people in the Ming Dynasty, you will definitely go bankrupt and jump off the building. In ancient times, only the ideas of those rich children could be more consistent with the ideas of modern youth. Strictly speaking, young people in modern society live the life of children of rich families in ancient times, which the poor dare not imagine.

Therefore, if you want to make the soap business bigger in Daming, you must emphasize the cost issue. Only when the cost is low enough and the price is low enough can we occupy the market. Otherwise, you can only make high-end soaps. The market is also large, but it is definitely difficult to do it to a large extent. At the very least, it will be difficult to make up for the huge trade deficit of the Beihai State with the Ming Dynasty.

And whale oil happens to be the lowest-cost oil! Whale oil cannot be eaten, so it cannot be sold at a price and can only be a cheap industrial grade oil.

In addition, whale oil is not dry oil, and the quality of the oil paper made is not as good as the oil paper made by tung oil. The only thing that is stronger than tung oil is that it is not slightly toxic like tung oil. Therefore, tung oil paper is not suitable for food wrapping paper. Whale oil paper, on the other hand, is possible. Because, whale oil is not toxic. Its iodine value, between 110 and 135, is a semi-dry oil.

Therefore, whale oil can be used to make oiled paper like dry tung oil (just a little less quality), and it can also be used as a lubricant like non-drying oil (which is also slightly worse quality), and it can also be used to make soap.

In conclusion, in the industrial field, the application of whale oil is very wide. In addition to being used to make candles, soap and oiled paper, whale oil also acts as a lubricant of general quality and can also be used in the dairy refueling process of the tanning process.

This process makes the leather softer, and at the same time, the toughness and strength are improved, and the water resistance is also improved. In later generations, whale oil was also a very high-grade oil for tanning.

It just so happened that Marin's people went to the Northeast to buy mink and needed post-processing. Whale oil, on the other hand, is a good raw material for refining mink.

Moreover, the cost of whale oil is very low! Because, in this era, the ocean is full of whales. They are giants in the sea, and sharks are also little brothers in front of them, so it can be said that they have no natural predators. So, this stuff is easy to get these days. The premise is that you have a whaling cannon that can kill them efficiently.

As long as you have a whaling cannon that can kill whales efficiently and quickly, whaling is simply at your fingertips on the seas of this era. Just see the water column spewed by the whale, the ship leaned over, the whaling cannon was aimed at a shot, and a whale weighing dozens of tons would be planted......
