In the 70s and 80s of the last century, the use of aluminum pans was prevalent in rural areas. This sturdy, shiny white aluminium pan is made from just a few cans.
These colorful cans were forged by rural craftsmen, and an aluminum pot was born.
In the childhood memories of many post-80s generations living in rural areas, aluminum pots and pots must be uncommon, not only used in their own homes, but also seen in neighbors' homes. For the rural people at that time,I can't wait for everyone to have an aluminum pot
At that time, people were more frugalEven the clothes are mostly "sewn and mended for another three years".
Rural people who are accustomed to spending money on the edge of the knife can't put down this kind of "local materials" aluminum pot.
At that time, it was popular to "pour aluminum pots", and craftsmen used a certain number of cans and "forging masters" to forge a white and bright aluminum pot at high temperatures.
As long as the craftsman's skills are good, and the forged aluminum pot is durable and beautiful, then people from near and far will rush to go. At that time, aluminum pots were not only common materials and fast forging, but farmers only needed to spend some manual fees to bring aluminum pots home. This kind of "processing" method in the market is much cheaper than the finished pot on the market.
For the rural people who are budget-conscious and hard-workingThe aluminum pot is simply a "dream pot".。In addition to forging aluminum pots from cans, farmers also ask craftsmen to help them forge aluminum pots. The aluminum basin forged with the "inverted aluminum pot" is not only lightweight and wear-resistant, but also can be used for a long time. Therefore, it has also been used in the market"One pot and one pot for three generations".to describe the quality of these finished aluminum products.
In addition to being economical, beautiful and durable, aluminum pots also have many advantages. Chemically speaking,Aluminum is a light metal that conducts electricity and heat easilyAnd it's very malleable.
Therefore, the aluminum pot made by craftsmen with traditional skills is very light and easy to use when stir-frying.
In addition, aluminum's extremely strong thermal conductivity allows it to heat up quickly, improving cooking efficiency and saving time. And, the aluminum pan has a very goodThermal insulationIt has greatly facilitated the lives of the masses of the people.
In addition to that,Aluminum pans also have some drawbacks。For example,A large amount of waste gas and waste residue generated during the smelting process will cause environmental pollution. In addition, in order to smelt a strong and beautiful aluminum pot that has been used for a long time, it takes an experienced craftsman to make it.
In the past, aluminum pot forging was a high-income type of work, so it was inevitable that some "Jianghu **" pretended to be craftsmen and delivered unqualified aluminum pots, which laid hidden dangers for farmers' economy and health.
The craftsman has excellent skills, the quality of the aluminum pot is guaranteed, and the farmers also love the aluminum potGo both waysHowever, in 2012, the aluminum pot forged by traditional methods suffered a catastrophe. Many people in the market have pointed out that aluminum pans contain carcinogens, which are harmful to human health.
What is the basis for this myth? It turned out to be from our country in 2012Food safety risk assessment report
In this national report, the whole country is clearly presentedAt least 400 million people have exceeded aluminium intake。The word "aluminum" in the report makes some people intuitively think of the aluminum pots that are used in every household. Who knows,Once out of someone's mouth, it becomes uncontrollableUnder layers of distortion, the news gradually evolved into "aluminum pots are toxic" and "aluminum pots are carcinogenic".
In addition, it is also reported that regular use of aluminum pots can lead to chronic aluminum poisoning, which in turn induces symptoms such as memory loss and physical fatigue. Then, the aluminum pot known as "one pot for three generations".Is it really so unsafe?
Scientifically speaking, aluminum pans exposed to air in direct contact with oxygen will form a dense oxide film that acts as a barrier, and the aluminum itself is very stable.
In addition, if the human body wants to meet the conditions of "aluminum poisoning",Constant inhalation of aluminum powder in an industrial environment is required for aluminum poisoning to occur. In real life, people only use aluminum pots for cooking, and it is very likely that people consume less aluminum from aluminum pots than the fritters they eat every morning.
Just because the aluminum pot contains aluminum elements, the rumors of "aluminum pot carcinogenic" and "aluminum pot poisonous" are confirmedThere is really no evidence.
Modern people may not be so familiar with the "poured aluminum pot".Some people also think that the "poured aluminum pot" is just a "flower shelf" that circulates among the people. Actually"Pouring aluminum pot" is a traditional handicraft。So,What does the real "inverted aluminum pot" look like?
The "pouring aluminum pot" process is mainly divided into two stepsOne is to turn the cans into aluminum, and the other is to cast hot aluminum. In the first step, the assembled cans or blocks of aluminium are smelted at a high temperature of about 700 degrees Celsius. This smelting process requires great patience and skill, and the craftsman has to endure the "stench" that reaches the sky during the smelting process for a long time.
After the aluminum is smelted, it is necessary to move on to the second step while the iron is hot, that is:Casting molding。In addition to the aluminum pot model, there are also some pot lids and aluminum pot models for people to choose fromAfter the hot aluminum is cast into the modelWait patiently for it to cool downCan.
After these two major steps, the aluminum pot did not meet the conditions for delivery. After all, the craft industry depends onWord of mouthIf the delivered aluminum pot is a defective product and people find out, then they will lose the trust of the villagers. At this time, the craftsman needs to be solid to the aluminum potTake the testAfter the quality and shape are not in question, the craftsman will also take out an iron file to finely polish the raw edges of the aluminum pot to make it smooth and secure.
Now, in addition to being misleading, there is also a very important reason for the fall of the aluminum pot in the market. With the improvement of people's living conditions, although the pursuit is not only the problem of food and clothing, modern people pay more attentionHigh quality of life。Therefore, the emerging various industrialized and technological pots have become the preferred choice in people's hearts.
For the rural people in the first decade of the last century, only a good aluminum pot can make a meal that meets the taste of the whole family, and such a table time full of temperature and family affection is a precious memory in the hearts of many people.
It's just that "the flower is not red for a hundred days", and the aluminum pot is "lost" after all, thanks for reading.
