After Zhu Houzhao taught the Bahus the correct business model, the fresh chemical product of soap finally became popular in Beijing.

Not only Wei Bin's Wei Ji shop, but the soaps from the shops such as Qiu Ju, Luo Xiang, and Liu Jin were basically sold out in a very short time.

The shops had to add orders, while the Royal Industries soap manufacturing team became extremely busy.

Under Zhu Houzhao's initial arrangement, there were only ten Xiao Neihuan who participated in the soap making, but now Zhu Houzhao has added twenty Xiao Neihuan to participate in the soap making.

Because soap is gradually becoming popular in Beijing, more and more shops come to order directly with Royal Industrial Company, and even in the end, vendors who ordered soap in batches lined up.

"Original, at first, Weichen begged those shops to purchase goods, but now Weichen doesn't need to ask for it anymore. He rushes to order the goods one by one, and even paid the deposit in advance. Now he even has more than 4,000 taels of deposit," Wei Bin said to Zhu Houzhao excitedly.

Luo Xiang also reported: "Emperor, now there are more people buying soap, and our raw materials purchases are also much higher. Because we are purchasing more and more, those who sell alkali noodles and lime are willing to lower prices for us. Now we can make a lot more money by selling a piece of soap."

Qiu Ju also reported: "Not only that, the soap transaction has been opened, and the soap-making officials at the Royal Industrial Experimental Base have also become much more active. They also have shares now. They know that they make more money by doing more. They work overtime and can make more than 10,000 yuan of soap every day."

Zhu Houzhao just smiled faintly after hearing this: "This is just the beginning. There is no need to be too happy too early. It's just a few cents of profit for a piece of soap. In the future, when there is a profit of tens of thousands of taels a day, it's not too late for you to be happy. The manufacturing of glass cannot be slow. The trend of soap being snatched up will expire. After all, people who buy soap cannot buy soap again. We have to think of other ways to make more money."

After Zhu Houzhao said this, Qiu Ju, Luo Xiang, Wei Bin and other Bahus hurriedly said yes and no longer had any resistance to the emperor's intention to make glass. In their current opinion, the new glass the emperor wants to make must be profitable.

The reason why it is called new glass is because there is not glass in the Ming Dynasty. However, the glass produced by the Ming Dynasty is not large in shape and generally cannot be transparent and colorless. The glass that Zhu Houzhao wants is transparent and colorless, and can be blown into various glass containers and low-cost large glass that can build greenhouses.

Zhu Houzhao first asked Qiu Ju to find craftsmen who could build glass-making kilns, and built glass-making kilns on the Royal Industrial Experimental Base, the former Royal Xiyuan Tu'er Mountain, and recreated the crucible.

Using crucibles to burn glass can directly use coal with higher combustion values ​​as fuel.

The crucible can isolate the contamination of glass liquid by sulfide in coal.

In addition, Zhu Houzhao also asked someone to apply graphite on the base of the crucible to achieve even heating when heating with the crucible.

Graphite does not exist in nature as a compound, and it is not difficult to mine and can be purchased on the market.

As for the raw materials for refining glass, the raw materials have also been improved, not only basic materials such as quartz, limestone, feldspar, and soda ash, color removal oxidants and other materials.

Soon, Zhu Houzhao refined colorless glass liquid with the help of a skilled old craftsman in the glass factory. Then, he naturally just put the glass liquid directly on the mold. The large piece of glass is fine, and it is evenly extended before the glass liquid solidifies. However, it is not easy to obtain standard experimental glass instruments.

The weights and measures of this era are different from the basic units of measurement in later generations. Zhu Houzhao used the data relationship between the current popular weights and measures and the basic units of measurement in later generations to determine a standard glass experimental instrument mold based on memory.

For example, a 250-ml volumetric flask and a 500-ml beaker, and then these craftsmen were instructed to blow them according to his requirements.

In the Ming Dynasty, mechanical blowing was naturally impossible, so it could only be blown manually, that is, put the glass liquid in a mold and blow it with a metal blowing pipe while turning and blowing, and then a large number of quantitatively significant glass experimental containers were created.

With glass experimental instruments, Zhu Houzhao was much better with solution and quantitative chemical reactions. For this reason, he specially asked Qiu Ju to build another laboratory at the Royal Industrial Experimental Base, and directly named it the Chemical Laboratory.

Zhu Houzhao will further develop new chemical products in this chemical laboratory. The main ingredients of soap are glycerin. Glycerin can not only be used to improve the skin, but also an important chemical raw material. Now Zhu Houzhao will react glycerin with nitric acid to make nitroglycerin.

Nitric acid is naturally not difficult. Today, the Ming Dynasty already has gunpowder. If there is gunpowder, there will be saltpeter. If there is saltpeter, it will be no problem to make nitric acid.

Qiu Ju is now very interested in chemical engineering. Following Zhu Houzhao, he is not only familiar with the soap production process, but also knows a lot of chemical knowledge. Zhu Houzhao even takes the initiative to teach him some. Now Zhu Houzhao has asked him to be responsible for the preparation and purification of green alum, that is, to produce concentrated sulfuric acid.

Because to make nitroglycerin, nitric acid must be made. The simplest way to make nitric acid is to react concentrated sulfuric acid with saltpeter to produce nitric acid. However, nitric acid and sulfuric acid are both strong acids and are very dangerous. Zhu Houzhao naturally won't take risks personally. Since Qiu Ju is interested, he naturally asked Qiu Ju to conduct experiments for himself.

Qiu Ju was very serious under the command of Zhu Houzhao, boiling green alum into concentrated sulfuric acid by distillation, and then quantitatively reacted part of the concentrated sulfuric acid with a determined concentration of sodium hydroxide solution, so as to determine the concentration of the obtained concentrated sulfuric acid.

Finally, two hundred and fifty milliliters of concentrated sulfuric acid solution with a certain concentration were prepared.

Zhu Houzhao was very pleased with this and couldn't help but boast about Qiu Ju: "Very good. Now the whole world is probably the only one who can determine the volume and mix the solution. In addition, among the three acids and dialcohols, you can already make one acid and two alkalis. With this, I will definitely give you the treatment of the second grade or above in the future, because you are now considered the title of great chemist of the Ming Dynasty!"

Qiu Ju was very happy after hearing this. Although he didn't know what a great chemist was, he knew that the treatment of the second-rank was a very top-notch treatment. There were not many people in the Ming Dynasty. It was his dream to be the top-level person. He couldn't help but listen more actively to Zhu Houzhao's arrangements to continue preparing nitric acid.

Under Zhu Houzhao's command, Qiu Ju first put the concentrated sulfuric acid into a gooseneck flask with gravel, then placed it on a wire mesh and heated it, and then poured it into a glass reactor. When the concentrated sulfuric acid is hot, add saltpeter and then stir slowly until the saltpeter has completely melted and precipitated and precipitated. Zhu Houzhao asked Qiu Ju to stop adding saltpeter, and then nitric acid was prepared.

Not long after, Zhu Houzhao took the nitric acid that had already been fixed from Qiu Ju's hand, and couldn't help but praise Qiu Ju again: "What a good slave! Now you have learned to make two acids and two alkalis, but you have to continue working hard. According to the plan I gave you, react this nitric acid with glycerin. If you can make nitroglycerin, I will reward you with 10,000 taels of silver on the lunar calendar and award you the honorary title of the Royal Highest Science Award! At that time, I will personally present you to the Ganqing Palace!"
