The mystery of polishing of single-handle long-handled flat-lid pot: the dual secret of beauty and durability?

In the production process of single-handle long-handled flat-lid pot, polishing follows grinding and becomes the key step between casting and finished product. Although grinding can remove the flaws and unevenness caused by the casting process, the surface of the pot still retains tiny pores and scratches. Although these tiny defects are difficult to detect with the naked eye, they may become channels for the penetration of moisture, oxygen and corrosive substances, thus affecting the long-term service life of the pot.

Polishing is born to solve this problem. Through high-speed rotating polishing wheels and fine polishing agents, the polishing process further smoothes the surface of the pot. Under the action of the polishing wheel, the tiny particles in the polishing agent are like countless tiny craftsmen, finely carving the surface of the pot, gradually filling the tiny pores, eliminating scratches, and making the surface of the pot reach an unprecedented level of smoothness.

The most direct change brought about by polishing is that a layer of uniform and delicate luster is formed on the surface of the pot. This layer of gloss, like the second skin of the pot, not only gives the pot a brighter and more upscale appearance, but also invisibly enhances the overall style of the kitchen. During the cooking process, when the sun or light shines on the pot, this layer of gloss will reflect a charming light, which makes people's eyes bright and doubles the fun of cooking.

However, polishing brings much more than that. Behind the gloss, there are more profound scientific principles. Through polishing, the number of micropores on the surface of the pot is greatly reduced, forming a dense protective layer. This protective layer, like a natural barrier, effectively blocks the penetration of moisture, oxygen and corrosive substances, thereby greatly improving the corrosion resistance of the pot.

Another important role of polishing is to enhance the durability of the pot. During the cooking process, the pot needs to withstand the test of high temperature, oil stains, food ingredients and other factors. If there are micropores or scratches on the surface of the pot, these defects can easily become a hiding place for oil stains and food residues, which is not only difficult to clean, but may also affect the cooking effect. The polished surface of the pot body, due to the reduction in the number of micropores and the improvement in smoothness, makes it more difficult for oil stains and food residues to adhere, and it is more convenient and quick to clean.

Polishing also forms a perfect combination with the material of the pot body. Single long handle flat lid saucepans are usually made of high-quality stainless steel or cast iron, which have good durability and corrosion resistance. The polishing process further strengthens these characteristics, so that the pot body can still maintain a good condition during long-term use and extend its service life.

Although polishing greatly improves the corrosion resistance of the pot body, daily maintenance is also indispensable. When using a single-handled long-handled flat-covered pot, be careful to avoid using too rough cleaning tools or chemical cleaners to avoid scratching the surface of the pot body or damaging the polishing layer. After cleaning, the moisture on the surface of the pot body should be wiped off in time to avoid being in a humid environment for a long time to reduce the erosion of the pot body by moisture.

For pots that are not used for a long time, they should be properly sealed. A thin layer of cooking oil or rust inhibitor can be applied to the surface of the pot body to isolate air and moisture, further extending the service life of the pot body.
