What is the patina on all kinds of Wan Wen?

I don't know whether to scrape off this so-called patina for inspection. As far as antique Wan Wen is concerned, every kind has patina.

Ceramics have patina, and calligraphy and painting have patina. I really know too little about these two kinds. I guess I've been with them for a long time.

There's a joke in Jianbao program:

Expert, look at my stuff. It is ancestral and belongs to the Western Zhou Dynasty. Do you think so?

Expert: It was last week.

If it is really the Western Zhou Dynasty, patina is the product of wide opening. From the moment he came in, the experts hoped that they could not get up to meet him.

Although I know nothing about the patina of ceramics, calligraphy and painting, architecture and plants, I know a little about walnuts and strings, which is what everyone must talk about when talking about patina. Look at the calluses on my palms. Doesn't that mean I'm an old driver who washes dishes? Let me sum up what my predecessors said:

First, human filth.

It's a little disgusting. This is from my uncle, who has worked in an antique shop for twenty years. He said that the patina of bodhi on this walnut is a human measure. Look at those kebabs in the market. After eating fried dough sticks in the morning, I picked up a pile without washing my hands and began to stroke them. When you meet love sweating in summer, you will serve them more quickly. Sweat is sour, slightly corroded and discolored, plus human fat, oil oozing out after wood is sour, and oil of fried dough sticks.

Therefore, it is said in the Jianghu that people who sweat a lot can't sweat a little.

Second, the deep communication between people and things.

After some players bought bracelets and walnuts, they began to turn over the forums. They must brush a few handfuls, walnut oil, hot towels of various thicknesses, fine cotton cloth and silk.

Generally, face towels are rubbed backwards first, then at night, played in your hand during the day, then changed into fine face towels, then cotton cloth and silk. After this cycle, it will be a year or two.

This kind of player just doesn't believe in the efficacy of sweat. What he slowly rubs is the oiliness and oxidation of the item itself, and the things he plays naturally look good and are not easy to crack.

I didn't look carefully to see if my bodhi was cracked. Experts say it will crack, but if you play well, the crack is also filled with slurry. I don't know. A player like me who hasn't played for a year is really blind to my string.

I want to show you a photo. I started for a year, but I have no food. In my hand, I said someone else brushed it with a brush. I just haven't played for two days.
