To get back to the point, since soap can be done by primary school students, it can be seen that the difficulty is not high, and the danger is certainly not great - of course, all chemical experiments are more or less dangerous, but since primary school students can do it, it can be seen that this danger must be completely controllable.

Of course, Gao Pragmatic also knows that this relatively primitive caustic soda manufacturing method must have various defects such as low efficiency and limited purity, but if it is only to cope with the current soap production, it is still not a problem.

However, an unexpected situation arose, because Gao Xiaozhuang asked: "Young Master, where should I buy these things?" ”

Gao Pragmatic is the eldest son of his father Gao Xuan, and Gao Xiaozhuang is the son of Gao Xuan, the "Xinzheng Gao Family Six Rooms", so calling Gao Pragmatic the eldest young master actually refers to the "Sixth Room Young Master", rather than the entire Gao family. After all, Gao Xuan himself is the sixth oldest among his brothers. In fact, so far this year, Gao Xuan alone has a total of six children, including four sons and two daughters. The three brothers under the eldest brother of Gao Pragmatic are Gao Wuguan, Gao Wuqin, and Gao Wujian, and the two daughters are Gao Yunhuan and Gao Yunting. [Note: Historical facts only record a few brothers, probably because of the patriarchal mentality, so the two daughters here are apocryphal.] Judging from Gao Xuan's age, Gao Xian may have to add a younger brother or sister in the future......

The tall young master didn't think about "where to buy" this stubble, but he was stunned for a moment, and said with a little hesitation: "The soda of the noodles is probably the price of the rice noodle shop, as for the caustic soda (that is, the common name of caustic soda at this time......)" Gao Pragmatic suddenly said a little speechless, caustic soda, as long as there is soda ash, it is not difficult to manufacture, but Daming actually has it or not, he really doesn't know, and even if there is, it may not be possible to buy it in large quantities, after all, people in these years may not have any demand for caustic soda, No more than soda ash can be used for this daily need of dough.

"Forget the caustic soda first, you go and ask the price of arginine." Gao Shi pondered for a moment, and then added: "Then go to those shops that sell building materials and ask about the price of charcoal ash." As for the lard, butter and the like, I don't need to talk about it, right? ”

"No, no, young master, this oil can definitely be asked by those butchers. However, the ambergris, civet incense, and sandalwood oil you talked about ......" Gao Xiaozhuang's voice began to decrease again.

Gao Pragmatic waved his hand in a grand manner, and said, "Go to the pharmacy and ask." ”

"Okay!" Gao Xiaozhuang patted his chest: "Don't worry, the eldest young master, it's wrapped in the little one." ”

Gao pragmatically advised: "You must remember the price of these things clearly, the stakes are very high!" ”

"I don't dare to say anything else, but my memory is pretty good, and you know it, young master."

Gao pragmatic nodded with satisfaction. Speaking of which, Gao Xiaozhuang can be picked as his scholar, in addition to the fact that the son of the family is naturally loyal to the master, his own intelligence is also the key. In fact, like the Gao family, a family of officials and eunuchs with family history, has its own set of standards for how to select suitable subordinates, and for such an important candidate as the eldest son of each house, it is not an exaggeration to say that the seriousness of its selection is probably much stricter than that of the Ministry of Officials inspecting a county order. Age, image, physical strength, loyalty, and even personality traits all belong to the scope of investigation and screening.

Gao Xiaozhuang only went out to ask for the price this time, and Gao Pragmatic did not pay him the silver money in advance. When Gao Xiaozhuang left the Gao Mansion, he called the two little girls who admired the moon and listened to the piano, and asked them to prepare some other tools that they needed.

Although it is not difficult to make soap, Gao pragmatic does things in accordance with some of the habits of his previous life when he was a secretary, and he still has to prepare everything that may be needed in advance, and first arrange trial production.

For example, although chopsticks or even wooden sticks can be used for stirring, Gao Pragmatic still asked the two little girls to find a jewelry store and specially order a few simple whisks that were more common in previous lives. At the same time, he personally supervised the work, hired a carpenter to make several wooden molds for the shape of the soap, and so on.

Although these things theoretically do not affect the success of the soap production, they can make the first trial soap have better quality and a more beautiful appearance, so Gao Pragmatic still made preparations in advance - after all, it is necessary to open the high-end market first, in addition to the obvious function, the most indispensable thing is to force the grid.

It didn't take long for the two little Loli to walk in with a few large and small boxes. The twins are also dressed in light green, which looks exactly the same, but Gao Pragmatic has been served by the two of them since he was a child, and he still has a way to tell the two sisters. In terms of appearance, there is a mole on the left sideburns of my sister's moon viewing, although it is very small, probably less than half a mung bean, but it is enough for Gao Pragmatic to distinguish the two of them.

As for the other differences, it is probably that the sister is slightly more courageous than the younger sister - although they are twins, they may have been instilled by their parents when they were children to take care of their sister, so the elder sister will play the role of a protector most of the time, while the younger sister is mostly in the position of being protected.

Even when he usually talks to Gao Pragmatic, he also admires the moon a little more, like now, first of all, he admires the moon and talks back: "Young Master, this 'blender' you made is really a good thing, and it is really convenient to use it when beating eggs." But why do you still need this thing for the soap you are talking about? ”

Gao Shishi saw that they had put the same things on the table, walked over and opened the box, and replied while inspecting it: "This is a long story. Well, the wire is pretty so-so, but it's not easy for this simple wire to rust easily......"

Tingqin interjected a rare sentence: "The slave heard that silver will not rust, and if the eldest young master wants not to rust, he can use silver to make a try." ”

Gao pragmatically smiled: "Silver is generally not easy to rust, but it is not suitable to make this thing from silver." He said to himself: When the scale of my soap industry expands in the future, how much silver will I need to make a whisk? And if it is made of silver, in case the management is not strict enough and someone takes it away, isn't it all a loss? Besides, it's not that there is no solution, it's nothing more than the use of stainless steel.

Of course, stainless steel is easy to say, but it is not necessarily simple. Although this stainless steel used as an egg beater can be easily made as long as there is chromium, in this day and age, it is necessary to find chrome ore at the first glance...... This seems a bit too ambitious.

So what to do? In the future, once the mass production is started, if the egg breaker is old and rusty, the size will also be a trouble.

Gao pragmatic couldn't help but fall into thought.
