My harem can't be this messy

Chapter 605 Soap and Glass

"Your Majesty, your name is Shixuan!"

Lin Shixuan came in and saw that the queen was here, and naturally bowed slightly to Li Zhi and the queen, and Li Zhi had already stepped forward to help her up.

"Yes, I am looking for you, and I am here this time to ask for your help!"

"Your Majesty, if you have anything to do, just ask."

"Soap Beans can do it, right?"

"This Shixuan Club, does Your Majesty want to add something to it? Or?"

"I don't add anything, it's just that I have a new recipe here. Let sister Shixuan help me make it. If it succeeds, I will make this soap bean here in Zhuyuan from now on."

"Your Majesty, take a look at Fang Zishixuan."

Naturally, Li Zhi had prepared it long ago, and his mother had already mentioned it to make soap and glass, and Li Zhi also got the specific materials and production methods from his mother.

However, due to the encounter with Xie Chong in Wanchun Palace recently, it has been delayed.

At this time, Huijing's master and apprentice had returned to Ganye Temple, and Li Zhi was also temporarily living in the Ganlu Hall.

After all, among all the women in this world, the queen mother is the most important thing in my heart.

The only caring person!Moreover, the mother's education and what she has mastered are simply a treasure house for Li Zhi.

For the queen mother, Li Zhi naturally did his best. The queen mother wanted soap and glass, so Li Zhi naturally had to get her out quickly.And these two things, to be honest, Li Zhi also needs them. After all, Li Zhi is also a person of later generations. Soap and glass are more comfortable to use by themselves, and they are much better than soap beans and bronze mirrors.

Moreover, once these two things are produced in large quantities, the economic benefits and far-reaching impact they will produce cannot be overestimated!

At this time, the prescription has been taken out. Apart from the materials, the most difficult part of soap making is the production of alkali. There are two kinds of alkali, one is caustic soda, which is the so-called sodium hydroxide, and the other is soda ash, which is sodium carbonate.At this time, caustic soda and sodium hydroxide were used.

The queen mother gave Li Zhi the production methods of these two methods, which came down to the saponification reaction. Later generations made soap, because there is a soap base, so it is very convenient, and ordinary people can make it, but at this time, it is a little more difficult.

The so-called saponification is the process of adding sodium hydroxide to oil to form fatty acid sodium under heating, which is actually the so-called soap base.

With this, soap making is extremely convenient, and the rest of the process can be quickly completed by an adult.

Lin Shixuan was holding the prescription given by Li Zhi at this time, and actually frowned a little, because the production of this prescription and soap beans was quite different.Completely not on one path.

"Your Majesty, are you sure this is the recipe?"

"Well, the things are ready, and the weaving girls in the weaving workshop can be transferred at will. Shixuan, it will take about a few days for me to come and pick up the finished product, and the finished product doesn't need to be too much. Just make a dozen yuan for the first time. Remember, Add some things when making soap at the end, which is the last list for you."

"Oh, Shixuan knows, Your Majesty will come to pick it up in three days, and Shixuan will be prepared."

"Well, try to find an open and ventilated place when making soap. The smell is not very good when making soap."

"Shixuan knows."

"Okay, you are busy, I have to go to the Ordnance Supervision."

The Ordnance Supervisor, one of the five supervisors of the Nine Temples of the Tang Dynasty, is dedicated to making various standard swords, swords, bows and crossbows. Naturally, it also makes other military equipment.Do both defensive and offensive.

When Li Zhi came here, people naturally came to welcome Li Zhi, and Li Zhi rarely came here, and this was the first time he came here as the emperor.

Accompanied by these people at this time, Li Zhi inspected the whole process of making swords, bows and crossbows, and took a good look at the Ordnance Supervision.

Li Zhi even tried a newly made crossbow here with his own hands. Li Zhi tried it and was very satisfied.

However, when Li Zhi came here, he did not come to visit or inspect, but to fulfill another order from his mother, to make glass.

To make glass, you need a high-temperature furnace, and at this time in Datang, this kind of furnace is the best in the ordnance department. After all, they need to smelt iron and steel to make swords.

Li Zhi still told the steward here what he needed, and also told the other party the specific production method.

The Nine Temples and Five Supervisors serve the royal family, and Li Zhi naturally trusts the people in the Ordnance Supervisor.

Making glass is actually not too difficult. Aunt Lin taught the method, so Li Zhi naturally found it easy at this time.

Very simple, high temperature, sand, baking soda, is sodium carbonate, the two methods of making alkali given by the mother, sodium bicarbonate is used for saponification, and sodium carbonate is used for making glass here.

Of course, Li Zhi had these two things, so it took a little effort to make soda ash at this time, and it was not difficult to make it. If this thing was made, it would have a huge impact on Datang's eating habits.

For ordinary people, the greatest use of soda ash is to leaven noodles. In fact, all kinds of noodles that people in later generations took for granted did not exist at all in the early Tang Dynasty. The so-called steamed cakes at this time were dead flour cakes.

The dead dough cake is hard, and the color is not good, and it is blue.The steamed noodles have a honeycomb-like soft structure, and the color has also changed greatly, which is almost the same as the big white steamed buns of later generations.

Of course, Li Zhi is not in a hurry to make soda ash at this time, he has to take care of his mother's affairs first.

Baking soda, that is, sodium carbonate, actually plays a catalytic role here, which can greatly reduce the melting point of sand, the main component of silica, and make silica easier to melt.

Li Zhi gave the method, and the steward here naturally agreed to it quickly.

Li Zhi also specifically mentioned a few points, such as the need to keep stirring in order to prevent a large number of air bubbles from being generated during the glass making process.

For example, when melting sand, it is best to use a special furnace.

After the matter was ordered, Li Zhi returned to the palace. After all, his status at this time made it impossible for him to wait for a few days at the Zhuyuan or the Ordnance Supervisor, waiting for the soap and glass to be made.

After returning to the palace, Li Zhi immediately went to find the queen mother. At this time, because there was the queen by her side, Lin Wanyue calmed down a little when she saw Li Zhi coming.

If Li Zhi was alone, Lin Wanyue would be nervous.

"Mother, Zhi'er went to the Bamboo Garden and the Ordnance Supervision today. What the mother ordered a few days ago, Zhi'er asked these two places to do."

"Well, the queen mother knows, how long will it take?"

"In just a few days, the sample treatment will be delivered to the queen mother."

"Queen, you go back first, I have something to say to my mother."

Li Zhi suddenly spoke at this time, Lin Wanyue instinctively pulled Wang Yan back.

"What's the matter, you can't say it in front of the queen!"

In the past, Lin Wanyue would never be like this. She hoped to be alone with Li Zhi, but at this time, Wang Yan became her shield.

"Yan'er, step back!"
