Is this soap?

The soap of the Tang family!

When a piece of soap was taken off from the wooden mold, Tang Runze looked at it in surprise.

These soaps are the soap-making methods that the eldest lady found in Western books. Who would have thought that the secret recipe for soap would be written in such a book?

It's just in a Western book.

The moment he picked up the soap, the surprise on his face disappeared.

"Miss, this ...... Soap doesn't seem to be the same. ”

Not quite the same?

Hearing this, Tang Ziqi also picked up a piece, and the soap felt a little soft in the hand, even sticky, which was completely different from unity soap.

"How so?"

In the Tang family's workshop, looking at the soap that had just been made, Tang Ziqi's brows furrowed.

"Steward Xu, this is the soap you made?"

Pointing to the pale yellow soap, Tang Ziqi asked rhetorically.

"Miss, this is made according to the method you gave."

Xu Lifu said with some grievances.

"And it was also in accordance with the method of the unity factory, and it was saponified for half a month."

Although it is not easy for the outside world to obtain the formula of the Unity Soap Factory, after all, there is a necessary process that is done at home, but there are still many production processes leaked out through various channels. From the production process of the plant to the process of maturation, it is not a secret to the outside world.

Even the current Tang family soap factory, it completely borrowed the equipment and process of the unity soap factory, and all this is what Xu Lifu brought from the unity factory, he is the foreman of the unity factory, it is under his introduction that the Tang family found Zhao Laosi to copy the water conservancy mixing and other processes of the unity factory, although there are no bearings available, but still let the Tang family's soap factory get rid of manual stirring.

Listening to Xu Lifu's answer, Tang Ziqi just nodded, and then she had to look at the method of making soap found in Western books again.

"First pour the ashes into the pot, then pour hot water and cover the ashes two centimeters. Let sit for two days or a week. After standing for two days, you need to put an egg for a buoyancy test, if the egg can float, it means that the concentration is up to standard. If you can't, let it sit a little longer......"

This time, Tang Ziqi did not look at the "secret recipe" he translated, but directly turned up the Western books he brought from Macao.

"Soap made from wood ash is not solid, but gelatinous...... The soap will turn into a brown gel the next day, and it will be wet to the touch, so you can use water to wash your hands......"

The soap is stored in a wooden barrel and can be removed and used immediately as needed. And such a gelatinous soap is certainly not the soap that Tang Ziqi wants. Solid soap is easier to carry and transport when sold in shops, so it is necessary to make solid soap.

“…… After boiling, salt is added at the last moment, and the soap that solidifies on the surface of the pot is made into ......"

Studying the method of making soap word by word, suddenly, one of the sentences, "Place it in a cool place until it is completely hardened", made Tang Ziqi say to himself.

"Is it because it hasn't been maturated long enough?"

It turned out to prove her suspicion, and after a month of sitting, the soap, which had been a little sticky, was finally hardened.

After Steward Tang delivered the first piece of hardened soap to the house, Tang Ziqi instructed the maids to try it first. First, I tried the effect of washing my hands.

"Go, Apple, go to the kitchen and get some oil on your hands, it's going to be full."

Despite some reluctance, Apple compliments and goes to the kitchen and gets a handful of pot oil, which is the most difficult to clean without soap.

If the soap of the Tang family can wash the oil of the pot, it will naturally be no worse than the soap of unity.

"Miss, then I'll wash ......"

Apple picks up the soap and rubs it in her hands, thinking to herself that if she can't wash it, she can always wash it with the unity soap she bought.

After a few moments, her greasy hands are covered in gray foam, and Apple puts her hands in the water and rubs them slightly, and the oil on her hands disappears as the gray foam melts into the water.

"Ah, Miss, our soap is no worse than unity soap!"

Raising her hand to see that the grease on her hand is gone, Apple immediately says happily.

"Well, it's not worse than theirs......"

Tang Ziqi nodded, looking a little proud.

"Apple, try your dirty laundry again!"

Soon, the next person sent a piece of dirty clothes, also from the kitchen, the oil that could not be washed in the past, rubbed soap on the stains, and then rubbed it vigorously for a while, and then put the dirty clothes into the water and rubbed it a few times, just like unity soap, most of the stains were washed clean! Even if it is the oil stain that can't be washed off, there is a lot of talk.

The soap at home is indeed no worse than the soap of unity!

Seeing this, Tang Runze hurriedly complimented.

"Miss, our soap is really amazing! It seems to be a little stronger than the unity soap......"

While he was talking, Tang Ziqi took the soap and washed his hands. Of course, there were no stains on her hands, but she just washed her hands there, feeling the smoothness of the foam.

"Steward Tang, as far as you say, our soap is sold on the street, can it compete with Unity Soap?"

The eldest lady's words made Tang Runze stunned, and after thinking for a while, his expression became a little solemn.

"Miss, if you sell it at the price of unity soap, I'm afraid you won't be able to make any money, and there is a problem with the yield, there is no problem with the oil, it is a little difficult to burn grass to get ash, and it takes a long time to soak the grass ash in water or to mature, speaking of which, Miss, I estimate that the soap over there is estimated to be different from ours, otherwise, why did they harden in fifteen days, but ours took a month?"

In this regard, Tang Ziqi almost had the bottom in his heart, so he asked again.

"How much money can we make from that piece of soap?"

"It is estimated that it is only two pennies, maybe it will be less, if the raw materials are more expensive, I am afraid that I will not be able to make money."

The housekeeper's words made Tang Ziqi depressed for a while, and finally made soap, but instead of making money, she might lose money, a reality that she couldn't accept no matter what.

Rubbing the foam on his hands, Tang Ziqi's face became a little ugly, but he couldn't say a word. Seeing that the eldest lady's face was ugly, not to mention Tang Runze, together with the personal maids who were usually chattering, they all stopped talking, for fear of making the young lady angry......
