Gong fight?Niang Niang, she dominated the cold palace by farming

Xu Ji pulled Song Qingzhai out of the way for a while, and explained to him: "The route here must not be messed up. Going the wrong way will delay their work."

Song Qingzhai lowered his head to look at the criss-crossing routes drawn on the ground, marked with some simple symbols that he could not understand.

He also came here when the arsenal was first established. At that time, the furnace was not so complete.

Xu Ji explained: "I made some rough plans, and then those who actually operated them gave a modification plan, and made a few revisions to get what it is today.

"I dare not say that it is complete, but after all, they use it smoothly and the work efficiency is very high."

The craftsmen were all busy, and when they saw them coming in, they just bowed and saluted before continuing to work.

Xu Ji said: "Their work cannot be stopped, otherwise this furnace of molten iron may be ruined."

Song Qingzhai couldn't help reaching out and rubbing her head, "Am I such a person who cares about etiquette?"

Xu Ji also laughed.

The voices of both of them were not low, and everyone who should hear heard it. She didn't say this to Song Qingzhai, but to those craftsmen.

Didn't the craftsmen's backs tense a lot after recognizing Song Qingzhai?

Xu Ji brought Song Qingzhai to a melting furnace, and raised his voice and asked, "What's the matter?"

The craftsmen here are familiar with her, knowing that she doesn't like red tape, so they just crossed their hands and saluted, and responded with a smile: "It's done! Princess, your method is really good! The newly made glaze is very bright!"

Xu Ji smiled and walked forward.

The craftsmen carried out a large piece of glass, which was illuminated by lights and fire.

Song Qingzhai blinked, "Such a large piece of colored glaze?" It was a full three feet square.

Xu Ji smiled and said, "This is not quite the same as colored glaze. I call it glass. Does it look similar to the glass mirror you gave me before?"

Song Qingzhai went over to touch it, then put his hand under the glass, looked at the clearly identifiable palm prints, and nodded, "It's somewhat similar, but the mirror is not transparent."

"Because the mirror is coated with something opaque," Xu Ji briefly explained, "but this one is not. Didn't you say that you got it by accident?
"I also thought about making some glass ourselves, but there is no prescription.

"A few days ago, they gave some glass beads, which were fired by chance. I found the materials they used, tried a few times, adjusted the recipe a few times, and finally made it, but the purity is not so good.

"Speaking of which, it's thanks to my elder brother that you made such a pure glass right after you came here!"

Although the craftsmen didn't know what use this thing would come in handy, seeing Xu Ji so happy, they were also very excited, "My lord, my lord, besides this transparent one, there are also a few colored ones. We will use the amount of materials according to the princess's instructions." It’s all recorded, see if you want to use it.”

"Use it!" Xu Ji happily replied, "Why don't you use it! We won't use window paper on our windows in the future, so we will use this. Do you think it looks good or not?"

The craftsmen showed longing looks.

Xu Ji made a promise: "After the first batch of glass is finished, I will replace the windows for you first. This is much more durable than window paper, and it is also windproof and rainproof."

The craftsmen cheered, but rejected her kindness: "Such a good thing should be used first by the princess and the prince."

Xu Ji waved his hand, "Why are we in a hurry! After the prescription is settled, let alone us, the whole Northland can use it!"

A craftsman couldn't help but whispered: "But the cost is also very high, I'm afraid many people can't afford it."
