"Pig iron water" is used to fill holes, but now it can be said that this pot-mending technology is extinct, so you'd better change it to a new pot.
There are two ways to repair the pot. If the crack is slight, use a pot-patching nail to penetrate it, twist the nail tail and wipe it evenly with mud. If the crack is large, repair it with iron powder. Firstly, the iron powder is boiled and melted, burned into molten iron, and then poured into the perforation in the pot. Under the perforation, spread a wet cloth to cool the poured molten iron and fill the cracks. After mending, burn the pot red and knock it flat with a hammer. Pot mending requires high skill, and it is well done by hand, so it is not easy to be detected.

You can buy it in a store that sells refrigeration equipment. Used as insulation pipe, wrapped outside the insulation layer to protect the insulation layer. It is used by people to mend pots. It is useful in many factories. If you are familiar with it, you can directly ask the maintenance point. It's a tin foil sticker, which is not sold in the supermarket. The vegetable market generally has stalls selling department stores, which are very cheap, one or two yuan.
You can buy one meter long.
If there is a hole in the iron pot, you can find a piece of broken casserole, grind it into fine powder, make it into thick mud with egg white, make it into a sand mud cake slightly larger than the hole in the pot, and then burn it on the fire for about two minutes, and the sand mud will be integrated with the iron pot. Or use lard mud, pound it into mud and fill it in the hole. The more it burns, the more it burns.
Tell a story, which contains the image process of pouring iron pots. Have a good time.
The Method of Disappearing from Modern Social Life ―― Tinted Iron Pot
"Ingenuity" is a compliment, but "craftsman" on the sidewalk means coolie, such as mason, carpenter, plasterer, painter and so on. Both doctors and teachers call themselves Mr. Although some teachers sometimes ridicule themselves as "teachers", after all, they mean to belittle themselves. No one will call them that in front of teachers. Even if people are behind their backs, they will only talk about this teacher or teacher.
In these streets, the "tinker" who specializes in repairing pots looks "humble", dealing with the small hammer of soot and charcoal fire all day, with smoke on his nose and eyebrows.
Mending cans is my favorite street. At that time, there was no such heavy study as now, and my parents and grandparents would not pick me up at the school gate every day. From kindergarten to the second grade school, I move, and every day when I come home from school, I will look at the pot-mending place for a while. Besides being curious, I also long for the blazing fire in winter. It seems to me that the tinker's inspiration is more important than what I got in the course of metal materials science a few years later.
In most modern families, a pot is really nothing. However, at the beginning of the last century and for quite a period after that, the proportion of pots in family property was much higher than now, and the saying that broken pots sell iron proved the importance of pots to some extent. At the end of 1950s, the whole country was struggling for an annual output of tens of thousands of tons of steel. Even the metal handles on many furniture have been pried off and sent to the earth blast furnace, and the iron pot is of course more important. In the most tense era, buying pots used to require special instruction tickets, so making up pots was a very popular street in that era.
I have seen a pot that has been used for many years. The thinnest part can be described as almost as thin as a cicada's wing, which should be very beneficial from the perspective of heat transfer efficiency. I've seen pots that have been mended countless times. There are hundreds of overlapping patches, and the pot may be heavier than the original one.
Pot patching can be divided into "cold patching" and "hot patching". "Cold patching" means that the pot repairer selects the corresponding mushroom-shaped nail according to the size and radian of the pot, passes through the small hole from the inside out, then passes through the small hole of a square washer, breaks the nail's foot and fixes it in the leaking place, and then gently taps the nail and the square washer with a small hammer to make them stick together. Interestingly, before selecting one of the pot-mending nails from his mouth and fixing it on the leaky pot, the pot-mending master will carefully put a circle of yellow mud around the foot of the small mushroom-shaped nail. I still can't figure out how the tinker made that mushroom-shaped nail with two feet.
"Cold patching" is convenient and quick, but its disadvantage is that it may prevent the spatula from turning over the food in the pot.
"Hot patching" is the best. The pot repairman put some pieces of broken iron pot into a small crucible, and also added other small iron pieces into the crucible. Now I guess this should be used to adjust the carbon content and expansion and contraction rate of hot metal. When it is ready, the pot-mending master buries the crucible in charcoal fire, and then pulls the bellows rhythmically, and the flame jumps happily with the rhythm of pulling the bellows. In summer, they kept jumping on the sweat of the tinker.
When the charcoal fire turns white, the pot mender will clean the charcoal fire and carefully skim the slag floating on the molten iron with a small spoon. This is an indispensable process. When I was a child, I thought that if I threw the dregs into the water, it would soon sink to the bottom. I once had the question, why not put the crucible on the fire like cooking? The tinker laughed and said, "Guawazi, iron won't melt like that." From then on, when I burned the iron tongs and branded the pig's trotters, I always put the iron tongs into the charcoal fire instead of putting them on the flame.
Hot patching has begun. At this time, the tinker's action is like a performance. I saw that he scooped out a spoonful of molten iron from the crucible with a small spoon and quickly poured it on a soft and round felt nested in the palm of his hand, some of which looked like talcum powder. After a few quick shakes, the molten iron turned into an orange ball. At the same time, the right hand put down the spoon, picked up another felt and rubbed it in the fine ash. Then aim the orange ball at the place where it needs to be mended, and gently squeeze it from the outside to the inside from the bottom up, and the molten iron will come up from the leak. The other felt will soon be pressed down and a light smoke will float out. After the felt is removed, it will appear as a pea-sized scar. After sewing a long seam, these pea-sized scars are tightly stacked together, which is a bit like a silkworm being raised to a small size.
The real hot patching process is not long, and a lot of time is spent on preparation work such as melting molten iron and polishing leaking pots. I once had doubts about the behavior of the pot-mending master: some loopholes were not big in the first place, so why did he stick them on the iron post, carefully tap them with a small hammer with a sharp mouth, or tap them into long and narrow cracks?
If there is a big hole in the iron pot, the process of hot patching will be more attractive. At this time, the standby pot master will choose a broken iron pot tablet whose shape and thickness are basically consistent with the leakage. If there is no ready-made one, he will choose a piece of similar size and knock it carefully. After knocking, it will be placed in a leak, often close to each other. Then fix the piece in the hole with a thin bamboo piece, then fix it with hot metal at three points, and then check whether it is flush. If you are not satisfied, knock again. When a circle is done, the pot mender will bake the pot by the fire to relieve the pressure. Hot patching does not need yellow mud. After patching, polish the hot patch with sand and gravel.
In the sixties and seventies of last century, at major celebrations, when fireworks were set off at night, it was often seen that a solution was scooped from an object similar to a crucible. I don't know what to hit it with, and the flames roared in all directions, which was spectacular. At that time, my first impression was that it was quite like molten iron scooped out by a tinker.
With the increase of iron and steel production in China, a large number of corrosive gases are produced when burning, and the honeycomb coal that seriously damages the pots and pans gradually withdraws from the family kitchen. With the gradual changes of society, the street of pot-repairing has almost disappeared. Although there are still a few stalls in some places to paste aluminum pot at the bottom, this is no longer a traditional mending street. When the pot is broken, people choose to give it to the recycler, and instead, a brand-new pot appears in the family kitchen.
Even so, I don't know if the tinker is still alive. I still vaguely remember the kind smile and the hands that were not afraid of burning when the tinker put the small sweet potatoes I picked up into the ash for baking. Thank you very much With a long knowledge, the story seems to have brought me to that distant era, and I miss it very much! Thanks again! That depends on the pot. If it's an iron pot, there's a magic trick:
1. First beat 1 pork liver on the chopping board with the back of a knife until it is juicy;
2. Remove the tendons from the liver juice, and mix it with gypsum with equal weight to form paste for later use.
3. Smooth the outer surface of the pot with fine sand ao paper in advance, then pour the pot upside down on the fire, burn the hole red, and immediately apply liver paste. Remember not to be too thick.
4. Put the pot straight and dry it with fire. Burn until the liver paste coagulates, and then wash the pot to use normally.
If it is stainless steel or aluminum pot, there is another magic method:
1. Grind the holes in the pan with fine sandpaper.
2. Turn the pot upside down and burn it red. Sprinkle some rosin on the perforated part as flux, and immediately contact the prepared fuse around the hole to melt it.
3. After welding, the washing pot can be used normally.
