After happily receiving the whale meat from the crew of the "Hunter 1" whale boat, the residents of Barewhale Port went back to cook and were disappointed. The taste was just that, and it might not even taste better than the mutton they often ate, and it was just for freshness. Therefore, they soon lost interest in these white whale meats.

While these residents were cooking whale meat, they were anchored in the processing workshop of the lower deck of the "Hunter 1" whale boat in the dock, a group of sailors were still steaming things in a small space filled with strange smells. This time it was not a blubber, but a whale bone. According to data issued by the Ministry of Agriculture, the bone weight of a whale accounted for about 10% of its weight. Zhang Yun believes that this number is not reliable. According to their rough weight, the weight of the sperm whale captured this time is about 10 tons, accounting for about 16% of its weight.

Whale bones are also good things that cannot be discarded at will! Sailors use tug-of-war to saw the whale bones into small pieces, then put them into the steamer, and also use hot steam for high-temperature steam, which can also squeeze out a lot of whale oil! Sailors use steam while passing in the steam while boring.

"Whale oil is very useful after being pulled back." Sailor Chang Ricardo sat in the corner of the processing workshop, chewing some tobacco in his mouth, and began to brag with everyone. In fact, he didn't understand these things very well. Many things were just heard from others, but these sailors were even less knowledgeable, so bragging with them was really stressful.

"It can be made of lubricating oil, light the lamp, eat it, soap, and even cream. How about it? Is it very useful?" Ricardo said with a smile. "This time this sperm whale is so big. No matter how we make a lot of money, we have made a lot of money. Look at whale oil, whale flesh, whale bones, whale skin, whale tail fins, whale liver and other internal organs, um... It's a pity that there are no whale baleen, so many things can be used. Think about the Dutch, British, French, Norwegian and Germans who used to hunt whales in the waters near the Svalbard. They usually only cut off whale blubber at sea, and then almost all the rest were abandoned in the sea. This is really a waste!"

"Boss, we caught such a big whale this time. How much bonus will we give us when we go back?" Some sailors asked everyone's most concerned questions.

"No less than 3500 yuan!" Ricardo sailors reported a number without hesitation, and then thought for a while and said, "It may even be more. Because the size of this sperm whale is too big. But the money is worth 60 people on our ship, and the gunners may get less. The remaining 36 of us may have a bonus of more than 300 yuan. Cheer, gentlemen! This is a huge wealth!"

The dozen sailors present blew loudly and everyone's faces were full of joy. Anyone who heard that they would get a lot of silver coins would be happy.

"Next time I'll catch a baleen whale!" Ricardo was a little excited at this time, and he said frostyly: "I heard from an official from the Ministry of Agriculture that many noble ladies are interested in bras, skirts or tights made by baleen, and they are willing to pay a high price for it - ah, everything is for beautiful ladies. It's as cute as yellow gold coins."

"Hahaha." The sailors present burst into laughter, and it seemed that when talking about the ladies, the men were always particularly excited.

Everyone chatted and laughed for a while, and then Sergeant Ricardo calculated the time and felt that it was almost done. Then he began to call the sailors to open the small pipes under the steamer, so that the whale oil boiled in the steamer flowed into the wooden barrel below. There was not a lot of whale oil squeezed out from the whale bones, but it was definitely not a decimal amount of accumulation. This shows the degree of prodigality of those European whalers.

The bone residue from the whale oil is also taken out, and then cooled and mashed into powder to make whale bone meal. That is the best phosphorus fertilizer. Moreover, whale bones will also fix some nitrogen during high-temperature steaming. Therefore, it is really a very excellent fertilizer, and the amount is quite large, accounting for about 6-7% of the whale's weight. The weight of this sperm whale is estimated to be close to 60 tons, which can get about four tons of fertilizer. Nowadays, various agriculture in China are developing greatly, and the demand for various types of fertilizers is very high. The phosphorus and nitrogen compound fertilizer made from whale bone meal are soluble in water and are easy to absorb, making it very suitable for the growth of domestic crops, especially various fruit trees.

In addition to whale bones, whale liver and some internal organs must also be processed as soon as possible. Among them, whale liver must be prepared to make cod liver oil. Some internal organs can also be made cod liver oil, but others can only be cooked into food. The internal organs of whale are rich in vitamins A and vitamin D. The cod liver oil preparations made can be used as nutritional health products or even medicines. They are very valuable for young children who need to supplement these vitamins. Some special parts of whale internal organs, such as the thymus, pituitary gland, thyroid, etc., can be used for pharmaceuticals, because these can extract more than 20 hormones. However, now it seems that this is really too high-end for the East Coast people at this time, so they can only give up.

In the kitchen next to the steamer, several chefs are also dealing with whale tail fins. Whale tail fins are a precious dish in later generations, with delicious meat. Some local travelers naturally have a good taste. They also had some instructions on this before leaving. At this time, these chefs are dividing the huge whale tail fins. They cut the tail fins into pieces, then scattered them with fine salt, and preparing to take them back to the local area.

After bringing these tail fins back to the local area, cut them into thin strips according to the meat texture, soak them in scald water several times, and after they cool down, add some seasonings to mix them, making a cold dish. The taste is not only delicious, but also very nutritious. If nothing unexpected happens, it should become a famous dish in the local area.

After this calculation, the East Coast people's use of whales has reached an outrageous level, which is many times more clever than the Europeans' method of extracting only whale blubber. It can be said that except for those whale skins, the East Coast people can handle almost all of them on board or in the baleen whale port. The whale skin is involved in the need of some chemical products such as soda ash, sulfuric acid and other substances, and it has not been processed yet, which makes Zhang Yun, the captain of "Hunter 1", a little depressed. Although the whale skin has been made into salt and hides the skin, if it is dragged for too long, it will have some impact on the quality.

However, the mayor of Balew Whale Port, Matthias, once again became Zhang Yun's savior. After listening to his complaints, Matthias said that since the island often tanned some cattle, sheepskin, seal skin, etc., there are many materials, and there are many good people tanning animal skins, so they can try to tannate whale skins.

Zhang Yun, who was overjoyed, immediately decided to let them give it a try. There was not much soda ash in the baleen whale port, but they could use lime water. In addition, a certain amount of sulfuric acid, alum and other essentials were stored in the warehouse on the island, so the conditions for tanning whale skin were almost complete.

In fact, there is nothing mysterious about tanning whale skin. It is nothing more than a few steps. One is to soak the water, that is, soak the salt to soak it back to the state of fresh skin. The water is generally 15 degrees, and the time of soaking depends on the time of salt drying, usually around 12 hours, in short, it is to make it soft. Since the whale skin of this sperm whale captured by the people on the east coast has only been salt dry for a few days, and most of the skin has not yet had time to store salt and still remain in the state of fresh skin, so this process is very simple.

The second step is to put the whale skin into alkaline water (add soda ash to the water) for saponification and degreasing reaction, that is, the oil and alkali react to form soap, and at the same time, scrape off the remaining fat, meat and other substances on the inner surface of the skin with a knife. This is a technical job. People in the East Coast have also explored for a long time to determine the ratio of various chemical components required for degreasing. At this time, the amount of soda ash is not large, so it is not impossible to replace it with lime water. At worst, it is enough to degreasate a few more times.

After degreasing, wash the skin repeatedly, press the oil, scrape the skin, and then put it in a solution of sulfuric acid and salt. After soaking for 24 hours, take it out and put it in chromium liquid (potassium dichromate taken out of the dye factory) for 48 hours, then take it out and peel it evenly, press the oil, and then wash it with water. Of course, if there is no potassium dichromate here, you can also use alum and other items instead.

In short, this is a long process, and it is not a particularly high-tech job. Europeans or Chinese in the 17th century knew how to tannate animal skins. The East Coast people only provided some chemicals to make the finished products obtained in this process higher quality and shorter time. The tanned whale skin thickness is about two or three millimeters, and can be used for clothes, shoes and even leather armor. The rain boots made of whale skin have excellent waterproof performance and will not deform and break in the cold winter. It is a high-quality leather. A whale skin can be made of one or two thousand pairs of rain boots, and it is not a problem that the skin of a big guy like sperm whale can make two or three thousand pairs of shoes.

It's really a treasure! Zhang Yun also sighed a little. This adult sperm whale weighing less than 60 tons is expected to eventually provide people in the East Coast with more than 2,000 pairs of high-end rain boots, about 13 tons of whale oil, 4 tons of compound fertilizer (whale bone meal), more than 11 tons of spiced whale jerky, more than 200 kilograms of cod liver oil, a large number of waterproof raincoat water capsules (whale intestine making), delicious tail fin meat, whale teeth crafts, ambergris and other valuable spices. The value of these products is Zhang Yunshi
