Price introduction and product use evaluation of copper pot

Pots are made of many materials. Generally speaking, we all use iron pots, not only because of the high cost performance and guaranteed quality. Or because iron is one of the essential elements in human daily life, iron pots can protect family members and their health to a certain extent. But in fact, there are many other pots on the market for you to choose from. For example, the copper pot recommended below is a representative one, and its price introduction and product use evaluation are involved. Interested friends can also refer to their own demand budget to analyze, I believe that when necessary, they can also buy satisfactory copper pots.

Second, how about using a copper pot? Why?

There are all kinds of pots in the kitchen: boiling pot, wok, steamer, pressure cooker, milk pot, flat pot ... But judging from the raw materials, there are generally only two kinds: iron pot and aluminum pot.

In the past, people also used copper pots. Humans discovered and used copper much earlier than iron, so they naturally used copper to make pots first. After the appearance of iron pots, some people still like to use copper pots. Copper is shiny and looks beautiful. Among metals, copper's heat transfer ability is second only to silver and better than iron. The biggest disadvantage of using copper as a cooker is that it is easy to produce toxic rust, which is what people call patina (hey hey? Like malachite). In addition, the use of copper pots will destroy vitamin C in food? .

With the development of industry, people find it really unfair to use copper as a pot. The output of copper is small and expensive. Used to make wires and motors (hehe? Including the chip in the computer), and even the manufacture of guns and bullets, in order to better play its characteristics (hey hey? Bombing the White House). So, the iron pot replaced the copper pot.

In the countryside, the cauldron on the stove is made of pig iron. Pig iron is hard and brittle, so it won't collapse if you tap it lightly, but it will break if you tap it again. Wrought iron can be used as wok and iron spoon. Wrought iron is soft and tough, and it won't break when bumped. The difference between pig iron and wrought iron is mainly the difference in carbon content. The carbon content of pig iron exceeds 1.7%, and that of wrought iron is below 0.2%. Iron pots are cheap. More than 30 years ago, almost all the pots in the kitchen were iron pots. Iron pot also has its shortcomings, which are relatively heavy and easy to rust. Iron rusted, like a scar, and fell off one by one. The heat transfer ability of iron is not too strong, not only inferior to copper, but also inferior to aluminum.

Now many utensils in the kitchen are made of aluminum or aluminum alloy. Pots, pots, shovels and spoons are almost all made of aluminum. However, a century ago, the price of aluminum was higher than that of gold, and it was called "silvery white gold".

The French emperor Charles Louis Napolé on Bonaparte treasured a set of aluminum tableware, which was only displayed at a grand state banquet. Mendeleev, a Russian chemist who discovered the periodic law of elements, was awarded a high prize by the Royal Society. An aluminum cup. These stories sound funny now. Today, aluminum is a very cheap metal. Compared with iron, aluminum has strong heat transfer ability and is light and beautiful. Therefore, aluminum is an ideal material for cooking utensils.

Some people think that aluminum will not rust. In fact, aluminum is a kind of active metal, which can easily combine with oxidation in the air to form a transparent and thin layer of aluminum rust-aluminum trioxide. However, unlike loose rust, this layer of aluminum rust is very dense and protects the interior from rust like skin. However, this aluminum rust film is afraid of both acid and alkali. Therefore, aluminum pot can't store dishes for too long, nor can it be used to hold vinegar, sour plum soup, alkaline water and salt water. Most aluminum products with rough surface are primary aluminum. Raw aluminum is impure aluminum, just like pig iron, it will break when you knock hard. Common aluminum products are light and thin. This is cooked aluminum. Aluminum alloy is smelted by adding a small amount of metals such as magnesium, manganese and copper to pure aluminum, and its corrosion resistance and hardness have been greatly improved. Pressure cookers and kettles made of aluminum alloy have been widely sold in the market. In recent years, anodic oxidation products have appeared in shops. This is because aluminum is oxidized by the electrode, which thickens the aluminum rust layer on the surface and forms a loose and porous adhesion layer, which can firmly adsorb dyes. So the surface of this aluminum lunch box, rice cooker, kettle, etc. Can be dyed into bright colors, making aluminum products more beautiful and attractive.

Aluminum pot also has its shortcomings. Excessive intake of aluminum can easily lead to Alzheimer's disease. So you'd better use stainless steel pot.

There is an old saying that people will die overnight. Tinned wine is also very popular in rural areas. Everyone must pay attention. If you have a stomachache, the doctor may not see the cause of your illness when you go to the hospital. In fact, this is called "lead poisoning".

The use of copper pots is not very common, because everyone is worried about its safety and quality. After all, the pot made of copper is slightly inferior in practicality and economy, so the above small series will analyze this problem for everyone, and give an in-depth example to illustrate the price knowledge and manufacturer's recommendation of copper pots. Friends who are interested in understanding can take this as an in-depth study. Or you can choose to buy a set of copper pot products suitable for you from the right platform.
