After an hour, it was no longer obvious that the previous bucket was oil, and it had turned into a thin, opaque yellow liquid. Continue to stir, and after two hours, it completely turned into a viscous consistency. Su Tang looked at each step. Once Zhang Cuilan finished drawing the eight characters and left traces, she knew it was done.
It also smelled of soap, and then he went over to lift the barrel down. The three of them worked together to pour the soap liquid into the box that was just delivered today.
Wait until the box is filled, and finally put the grid into the soap solution. You will see that the soap is naturally divided into small pieces one by one by the grid.
At this point, Su Tang could finally breathe a sigh of relief and said, "Carry it to the east wing, make sure it is ventilated and dry!"
The three of them then carried the box to the kang in the east wing together, and the rest had to wait for it to dry on its own.
After this success, before going to the Song Mansion that day, Su Tang specifically asked Zhang Cuilan to continue buying oil outside, at the same ratio.
Two days later, the carpenter delivered the second box. Su Tang took Zhang Cuilan and Mint to make a box of soap using the same steps. After making it, they spread a cloth on the ground in the yard.
After moving the first box out of the east wing and placing it upside down on the cloth, Su Tang tapped the edge of the box with a small hammer. Slowly, the solidified soap was demoulded from the box, and then peeled off again. The internal grids were replaced and turned into soaps of the same size each.
"Mom, this is really soap." Mint followed Zhang Cuilan to collect the soap, with a look of surprise on her face. It was hard to imagine that they made this thing by themselves. It was incredible that oil could make soap.
Zhang Cuilan couldn't imagine it either, but at this time she also understood why Su Tang warned the mother and daughter to be stricter on the first day and not to talk about family matters outside.
Of course Zhang Cuilan has never used soap balls herself, but even though she has never used them, she has always heard of them. The soap balls in the grocery store are not as big as the ones they make, and each one costs fifteen cents.
They probably need to sell it for this amount of money, but in fact, the cost of making these soaps is less than 300 cash.
But Zhang Cuilan soon realized that making this soap depends on the water added after the sugar. They didn't know what it was. Maybe it was very expensive.
Thinking like this, Zhang Cuilan pulled her daughter in after hearing what she said, "Talk less, do more!"
After being warned by her mother, Mint stuck out her tongue and did not dare to say anything else. She obediently continued to help make the soap and put it away.
Su Tang took it over and checked it. Sure enough, there would be no mistakes when weighing it with Orange Cat. The soap was of the same quality as usual. Su Tang nodded with satisfaction, "Not bad."
After that, the carpenter slowly delivered the remaining wooden boxes, and officially made soap once every other morning. Because a lot of oil was used, Su Tang directly asked Zhang Cuilan to contact an oil pressing shop and buy it directly from the shop. Oil, ten kilograms can be cheaper by five cents.
In this way, Su Tang's life slowly returned to a steady rhythm, and half a month had passed since Luo Xingchen left.
This morning, Su Tang and his younger brother were studying in the main room. Zhang Cuilan took the dried soap box out of the east wing with mint and prepared to unmould it, when she heard a rapid knock on the door.
Hearing someone knocking on the door, Zhang Cuilan and Mint both looked up in surprise.
