"Anachronism is a term used in the archaeological community. It refers to this thing in front of us, which appears to be something that is technologically advanced beyond the estimated age."
"Whenever something like this appears in the archaeological community, it always causes a stir."
"It seems that this time, we can't say that we have gained nothing..."
After saying that, Ren Yan sighed again, feeling a little sad about the luck of Class 9...
No, maybe it shouldn’t be called luck.
It must be luck.
Ever since he took over Class Nine, these kids always encountered all kinds of inexplicable things. In less than a year, they were almost as exciting as Ren Yan's previous life.
When I was still a corporate slave, there weren’t so many things to do.
"So...what's going on here, Mr. Ren?"
After hearing their teacher's explanation, everyone in Class 9 seemed a little at a loss for a moment.
In theory, they have encountered enough things and seen a lot.
But in this completely new field, they still instinctively felt a little timid.
"Let's see if our guess is right first." Ren Yan stretched out his fingers and looked at A Wei: "A Wei, go to the warehouse and get all the brushes and cleaning fluids you might need to clean the deck."
"Anyway, we have to first determine what this thing is, or its exact age."
"It's too badly corroded now, we have to give it a rough clean first."
"Are you sure... you want to use the tools to clean the deck?" Ah Wei seemed a little embarrassed: "Teacher Ren, although I don't know much about antiques, I have seen pigs run even if I haven't eaten pork~"
"Shouldn't this be something that a bunch of old historians with gray beards wearing white coats, holding magnifying glasses, and using equipment that can be accurate to millimeters to wipe it bit by bit?"
"You are so simple and rough, are you sure it's okay?"
After saying that, Ren Yan squinted his eyes, frowned, gritted his teeth, and asked in a rather painful tone: "Haven't you ever cleaned up rusty farm tools?"
"Although there may be a difference of several hundred years between the two."
"But you wouldn't think that metal would become completely brittle after a few hundred years, let alone after it has been in the sea for a long time."
"I'm not as delicate as you say. I'm not a young lady!"
"The ones you saw on the Internet are all the final fine processing. For metal products like these that have just been discovered, there are not so many things to deal with. If they are too fine, they may not be cleaned up completely~"
After that, Ren Yan waved his hands with a look of stomachache: "Alright, alright, don't be hesitant, just take it when I tell you to. You can learn how to handle it simply from me later."
“Oh~~~”
Hearing this, Awei agreed with his mouth and ran towards the warehouse with a few people.
Soon, he returned with large and small bags.
Judging from what Awei brought back, the other party carried out his requirements very well, but there may have been a slight deviation in understanding.
Looking at the iron pins in the cleaning tool, Ren Yan's mouth twitched uncontrollably again:
"No... I asked you to get a brush or something like that, why did you bring the happy ball over here?"
Ah Wei answered seriously: "This thing is very effective in cleaning stubborn stains. I think you can use it!"
Listening to the other party's painstaking efforts, Ren Yan weakly dropped his arms, and the words of reprimand were stuck deeply in his throat.
"Alright, alright, come here, everyone. Today we'll teach you how to clean up potential historical relics!"
Ignoring A Wei, Ren Yan looked up and glanced around, then called all the students in Class 9 over.
Because the 'suspected' stone object is so large, there is no need for special standing positions, and all students can see it clearly.
After seeing everyone standing in place, Ren Yan took out a brush from the pile of tools, dipped it in a bottle of white vinegar for a few times, and then poured all the vinegar on the person being treated.
He glanced at his watch and waited patiently.
While waiting, I explained to the students of Class 9:
"In principle, we are not allowed to use any chemical agents when dealing with historical relics, because we cannot be sure of the composition of the relics. If we accidentally damage the relics, the loss will outweigh the gain."
"So, generally speaking, vinegar is the most commonly used substance for removing rust from cultural relics. Vinegar has a weaker acidity and can remove rust over time. It is currently the safest way to remove rust."
"And this method is called vinegar soaking method in cultural relics cleaning."
"Besides that, there are mechanical, boiling water immersion, dry brushing and heating methods."
"However, compared with vinegar soaking, the other methods have too many limitations and need to be used in specific places."
"For example, for relatively small impurities, mechanical methods are often used. A person holds a needle and carefully removes the excess impurities, which requires great patience and perseverance."
"Boiling water is mostly used to deal with soil rust. Soak in water at 80 to 90 degrees for about five minutes, and a lot of soil rust will fall off, and other rust will also loosen."
"At this time, it is often used in conjunction with the dry brush method. When the rust is not heavy and can be easily cleaned, just use a soft brush to brush away the impurities. This is also the method you often see on TV."
"As for the last heating method, it is not much different from soaking in boiling water, but it is mostly used to deal with slight rust or cultural relics that cannot be soaked in water."
"Ours is too rusty now and obviously can't be used."
