1, mountain spring effect, optimizing water quality
Mountain spring water is the most ideal water for making tea, which is rich in various trace minerals, with less chloride content and sweet water quality. At present, strong oxidizing chlorine dioxide is usually added to drinking water in cities for disinfection, and tap water will contain residues after chemical reaction (disinfection), which will cause damage to cells and tissues if ingested into human body.
When boiling water in an iron pan, chlorine dioxide reacts with iron, which is converted into nontoxic chloride ions and water, and iron is converted into ferrous ions, which are immersed in water, so that the boiled water has the effect of mountain spring water.
2, health care, iron and blood.
Ferrous ion is extremely beneficial to human body: firstly, it is a strong antioxidant, which can effectively remove free radicals (substances that destroy cells and tissues) in human body and maintain health. There are two sources of ferrous ions in iron pot boiling water:
(1) the chemical reaction between oxidized substances such as chlorine dioxide and iron;
(2) Natural dissolution of iron. Experiments show that the use of iron pot boiling water can release a large number of ferrous ions easily absorbed by human body, which can effectively supplement human needs and prevent anemia.
3, tea weapons, players must.
The boiling water temperature of the iron pot is higher, 2-3 degrees higher than that of ordinary stainless steel, which can achieve real boiling (100℃) and the heat preservation time is longer. Soaking old tea (Pu 'er and black tea) at high temperature, especially Pu 'er old tea, must use enough high-temperature water because of its long aging time, so as to fully stimulate its inherent aroma and tea rhyme, and then enhance the enjoyment of tea tasting.
4, artistic enjoyment, love and edification
Iron pot's pot body is often decorated with exquisite ornamentation or landscape poems. Top grade iron pot will even carve gold and silver patterns on hanging beams, or plum blossoms or autumn chrysanthemums, which are simple and elegant, nuanced and pleasing to the eye. Raw iron pots give people a charm of traditional culture from the aspects of modeling design, material selection, firing technology and finished products.

Iron pot technology
1. In order to protect this craft, the iron pot has long been regarded as a traditional craft. This kind of work has excellent cast iron and traditional craftsmanship, and its classical iron muscle and simple style are regarded as pure Japanese creations, which are highly praised in Japan.
2. Iron pots, in particular, are representatives of many families and are highly respected; In order to keep up with the changes of the times, we still cast works in line with modern life based on traditional crafts, not only practical kettles, but also artistic handicrafts with decorative functions: such excellent handicrafts can be preserved and used for a long time.
3. The manufacturing technology of iron pot can be roughly divided into wax mold casting, sand mold casting and hard mold pressure casting. The appearance of iron pots made by wax casting method is very beautiful, and most of them are all-work; "Sand casting method" iron pot generally does not need the whole work except the pot with graupel pattern, and it is generally flat below the feather line; Generally, the shape of die-cast iron pots is exaggerated, and most of them are high relief patterns.
