my black moonlight girlfriend

Chapter 79
Xiong Daqi said, this is a new cave.In fact, it is not. It should be said that this is an abandoned cave, but I don’t know how many years it has been abandoned.

The earliest mining of realgar mines can be traced back to the Northern Wei Dynasty, and the two of them could not investigate the time when the mine was abandoned.

"I've gone down a few times, the water has been drained, and the oxygen is fine." Xiong Daqi tried it with a torch, and the flame burned normally, "I'll go down first."

Xiong Daqi has already installed screws and hanging pieces at the entrance of the cave, installed ropes, put on the equipment and went down the cave first.

Xin Wan also put on the helmet and headlamp, skillfully equipped her body, and followed Xiong Daqi down.

"It may be because it has been abandoned for many years, or it may be that the hole was not mined at the beginning, and there is nothing in it." Xiong Daqi said when he took her down from the rope.

She nodded. The mine is not deep, but only about 50 meters long. There is still a long section of their [-]-meter rope left, and there are indeed not many traces of mining. Walking in with Xiong Daqi, I only saw someone in the shale formation. For support, but also very old.

Going deeper into the mine, she could see the crust-like limestone breccia gaps or calcite network veins together with calcite, charcoal peat and other cements along the way.

Orange-red realgar and lemon-yellow orpiment exist in rocks in the form of veinlets, stars, or flakes.

Xin Wan majored in Chinese painting and geology at university. However, picking mines is really a job of experience. Grandpa relied on his lifetime of dealing with mines, and he has cultivated a pair of piercing eyes year after year. He has received professional training, and with his eyes and his simple methods, he can see clearly. When it comes to her, it won't work.

The gangue minerals are mainly calcite, as well as dolomite, quartz, chalcedony, charcoal, pyrite, mica, kaolinite, etc. How much realgar or orpiment is contained in a stone? She is not sure how much is used for color making, just like the azurite and malachite bought back last time, there are only a few that can be used for color making in the end, and there are a lot of impurities, she bleached most of them For a month, spread out the color with white paper, and picked out the impurities one by one. My eyes were almost blinded, and the color was still gray and dull. .

But Xiong Daqi is the son of an old mine owner, and he also studied this major. After graduating from university and returning to his hometown, he knows this industry better than her. Therefore, she still trusts him to a certain extent when it comes to picking mines.

"As for me, I don't know how you make the color, but I have measured it, and it is still a rich mine. As for whether it meets your requirements, it is up to you to see." Xiong Daqi pointed to the rock and said to her, holding His hammer occasionally knocked on stones, let her listen to the sound, and he laughed as he said, "My grandpa, use this hammer to knock, go out to survey and survey, draw pictures with a pen, and you will know what is there. Seeing that I am drilling again." , both geophysical and chemical detectives, laughing at me."

Xin Wan laughed, isn't this the same as grandpa? "Old people always have their own experience and persistence."

"Yes, they are a conservative generation, but they also have their unique skills." Xiong Daqi led her to the depths of the mine.

The ore orange and lemon yellow here are more abundant, and some of the two colors coexist together.

　It has been two days in a row that he has not appeared~~Actually, I know that some babies only like to watch the interaction between the male and female protagonists, but, it should be said that starting from "I Heard", Jixiang changed his writing method, and every subsequent article They are not simply about love and love, they will fill in a lot of other content, a book with a career, a theme, and try to make the stories written by the pen not only romance.This book is the same, or the content is richer. It mainly focuses on mineral pigments, and there will be other content related to it. In the future, the company I will work in is also something in another field. In fact, it is more difficult to write like this than to write purely about feelings There are too many, I have to interview different people on the spot, and I need to check a lot of information, but I think these are very interesting. Writing a book is also a door to a new world for me, so I only like to watch the hero and heroine. The baby of the opponent's feelings will be disappointed, but I can only express my regret~~~ And, the "A Thousand Miles of Rivers and Mountains" mentioned in the comments, yes, it is mainly painted with azurite and azurite (of course, there are other These two colors are made of azurite and malachite respectively~ This time I went to interview non-genetic people, not only saw how mineral pigments are made, but the old man also mentioned three words: patience, perseverance, and conscience.This is our Chinese craftsman spirit, I have benefited a lot, and I will keep these three words in mind and do my own thing~~
