First, the characteristics of the silver pot
Silver: English name: Silver, chemical symbol: Ag, which was called silver in ancient China.
Silver is a beautiful silvery white metal with good ductility, second only to gold in precious metals, and the first in electrical conductivity and thermal conductivity.
"Silver" has been closely related to human life since ancient times. Man has discovered and used silver for at least two thousand years. And silverware was once brilliant in the Tang Dynasty in China. At that time, the output of gold and silver utensils was limited, and users had strict grade restrictions, so the gold and silver utensils made were gorgeous and noble, showing the royal style.
1. Sterilization: The silver ions released by the manual silver pot when boiling water have the characteristics of high stability, low activity, fast heat conduction, soft texture and constant corrosion by chemicals. The positively charged silver ions produced in water can adsorb bacteria, shut down and inactivate the enzyme system on which bacteria depend, and achieve sterilization effect. As long as every liter of water contains one milligram of 50 million silver ions, it is enough to kill most bacteria in the water.
2, the role of soft water: boiling water in a silver pot can make the water quality soft and thin, which has a good soft water effect. The ancients called it "water like silk", which means that the water quality is as soft, thin, smooth and smooth as silk.
3. Deodorization and health care function: Silver is clean and odorless, with stable thermochemical properties, and it is not easy to rust, so that tea soup will not be contaminated with peculiar smell. Silver has strong thermal conductivity, which can quickly dissipate heat from blood vessels and effectively prevent various cardiovascular diseases.
Second, the characteristics of iron pot
1, iron supplement expert: Scientists have found that iron is a hematopoietic element, and adults need 0.8- 1.5 mg of iron every day. Severe iron deficiency will affect intellectual development. Experiments have also proved that using iron pots, iron pots and other raw iron utensils to drink water and cook can increase the absorption of iron. Because boiling water in iron pot can release ferrous ions easily absorbed by human body, supplement the iron needed by human body, and effectively prevent iron deficiency anemia.
2. Sharp tool for making tea: The boiling point of boiled water in iron pot is higher, 5-6 degrees higher than that of ordinary stainless steel, and the heat preservation time is longer. Making tea with high-temperature water can stimulate and enhance the aroma of tea. Especially for old tea, due to its long aging time, it needs enough high-temperature water to give full play to its inherent fragrance and tea rhyme. Iron pot has become a professional tea set for tea lovers at the player level to taste tea, fight tea, taste tea and carry out tea party activities.
3. Efficacy of mountain spring water: Mountain spring water is filtered by sandstone layer under the mountain forest, and contains trace minerals, especially iron ions and a very small amount of chloride. The water quality is sweet and it is the most ideal water for making tea. Iron pots can release trace iron ions and adsorb chloride ions in water. The water boiled in an iron pan has the same effect as mountain spring water.
4. Appreciation and collection: The relationship between tea set and tea is as inseparable as the relationship between water and tea. The quality and aesthetic feeling of tea sets affect the quality of tea tasting and the mood of tea tasters. The ancients said that "vessel is the father of tea and water is the mother of tea", so tea set is an important element of tea ceremony aesthetics. It is essential to add a iron pot with exquisite workmanship to the coffee table. The outer coating of iron pan is food-grade material, which is painted by high temperature process, non-toxic, wear-resistant and high in strength. With the increase of scrubbing times, it will show the dim light of metal texture more and more, especially giving the appliance new vitality and unique ornamental value.
A pair of iron pot and a silver pot can basically meet the needs of brewing, so that the taste and fragrance of tea can be brought into full play. The thermal conductivity of iron is 80W/mk, and that of silver is 429 W/MK. The larger the value, the better the thermal conductivity, with a difference of 4.3 times.
"The silver pot carries incense, and iron pot carries rhyme."
Handmade silver pots are suitable for brewing lightly fermented tea, such as Tieguanyin and green tea.
Iron pot is suitable for brewing tea with heavy fermentation process, such as black tea, black tea (Pu 'er, aged tea, etc. ).
Therefore, most people who love tea think that the best effect can be achieved when the silver pot and iron pot are used together.
