In this era of change, our way of life has undergone tremendous changes. Once upon a time, those things that were loved by the public have now faded out of history, like a flash in the pan, as if they were only drowned by the merciless years in an instant.
Every time I look back at those memories that have been sealed by the dust of the years for a long time, I can't help but feel nostalgic for that distant and familiar era, and an indescribable intimacy can't help but come to my heart.
Let's look back at that time fragment that is completely different from the present, the once ubiquitous "pouring aluminum pot" technique. There is no doubt that in those days, whether you were on a bustling city street or a quiet country alley, you could easily capture the busy figure of craftsmen with heavy burdens and aluminum pot tools in hand.
Carrying heavy bags on their backs, they weave through the bustling bazaars in search of the next stage where they can showcase their skills.
Today, however, these scenes have faded away, becoming a glimmer of the past. Nowadays, it is difficult to find those busy figures of "pouring aluminum pots" craftsmen in the streets and alleys.
That era that was once all the rage seems to have been left behind in a corner of people's minds with the passage of time. We have to sigh that a traditional industry has quietly disappeared from people's field of vision and is far away from our lives.
In those days, despite the harsh living conditions in the countryside, the enthusiastic villagers could always find their own happiness. At a time when the choice of goods was scarce, aluminum pots undoubtedly became the ideal kitchenware in the minds of rural residents, with a wide variety, low prices, rich capacity, and almost anything.
Whenever the village market is approaching, the craftsmen who carry shabby bags will become the center of attention. Their skillful arrangement of tools such as crucibles, molds, and gas canisters is a unique scene that always attracts many curious villagers.
As soon as all the preparations are in place, the masters are immediately engaged in this fascinating process. The farmers in the village have already sorted out the various cans and old aluminum products collected in their daily lives and can't wait to hand them over to the masters.
In this painstaking process, the craftsmen did not hesitate to throw all of the jumble into boiler-shaped crucibles and heat them with a blazing flame until the entire aluminium was completely transformed into a glittering liquid molten aluminum.
The next scene can be called the most eye-catching thing in the whole process. Craftsmen carefully pour red-hot molten aluminum into specially processed casting molds, while quickly covering them with a fine layer of grit.
The role of this layer of grit is not only to promote the process of cooling and solidification, but also to make the bottom of the finished aluminum pot shine charmingly, showing a unique interweaving of simplicity and refinement.
All those present tensed their heartstrings and waited patiently. A moment later, a new and bright aluminium pot was born. Seeing the scrap materials they once collected come back to life, the farmers smiled with joy and expressed their sincere admiration and gratitude for this skilled craftsman.
However, who would have expected that this otherwise ordinary craft would become the focus of attention at some point in the future. At that time, rumors were rife and all kinds of gossip spread on the Internet.
Just more than ten years ago, a rumor that "aluminum pot is poisonous" spread wildly on the Internet. According to people familiar with the matter, all this stems from the research reports of some foreign doctors.
At the time, they were studying the symptoms of dementia in some patients who were undergoing hemodialysis treatment, and found that the culprit was an excess of aluminum ions in the dialysate.
Subsequently, more researchers looked at people with dementia and found that their brains also had unusually high levels of aluminum. It can be seen that the damage of aluminum to the brain is obvious.
In this virtual online world, this rumor quickly fermented, and the public's fear of aluminum products reached an unprecedented level. Some people even directly assert that in a high-temperature environment, highly toxic aluminum ions will be precipitated from the inner wall of the aluminum pot, and long-term consumption of food cooked by it will directly damage intelligence and eventually lead to dementia.
This outrageous lie has stirred up panic among the public. Those aluminum pots, which were once regarded as treasures, became the target of public criticism overnight. When pedestrians saw the aluminum pot, it was like seeing a fierce beast, and the insults came and went.
"Pouring aluminum pot", a traditional skill that has gone through the vicissitudes of life, has silently withdrawn from the stage of history. In the midst of many cynicisms and accusations, these craftsmen had to pick up the tools in their hands again and re-enter the familiar but distant world.
Although everyone was shocked by the possible health risks posed by aluminum, the mainland's medical elite did not weaken their resolve.
On the contrary, with a rigorous scientific attitude, they have made an in-depth and authoritative interpretation of the hazards of aluminum, and successfully eliminated the doubts in the minds of the public.
Experts stress that we must first be clear that although aluminum does pose a certain potential threat to the human body, "talking about toxicity regardless of dosage is tantamount to playing hooligan".
They elaborated that the neurological disorders observed by early doctors were mainly caused by patients ingesting excessive amounts of aluminum salts over a long period of time.
At that time, the high concentration of aluminum ions in the dialysate was due to the use of drugs with too high aluminum content in the treatment process. The high levels of aluminium in the brains of patients with dementia were only caused by their long-term consumption of foods containing high doses of aluminium additives.
For example, alum that was once widely used, as well as some leavening agents containing aluminum, etc.
In contrast, the amount of aluminum ions released by an aluminum pan during daily cooking is negligible. Experts candidly say that even if a person has used an aluminum pan all his life, the total amount of aluminum ions he will consume will not exceed the amount of one fritter (at that time, fritters were commonly used with aluminium-containing leavening agents).
"This value is far lower than the limit standard for food additives in any country." The expert firmly said, "The metabolic function of ordinary people is completely able to excrete all these trace aluminum ions from the body, so there is really no need to worry too much."
In addition to its extensive use in the kitchenware sector, aluminum foil also plays a pivotal role in the pharmaceutical industry and food packaging. From the aluminum foil sealing of boxed medicines, to the aluminum foil lining of dairy packaging, to the insulated bags of takeaway fast food, etc., the ubiquitous appearance of aluminum foil bears witness to its importance.
