Pinch, also known as "iron tire", has a thick carcass, which can keep tea warm, but it is difficult to be cold after long heat. It is made by high-temperature back-firing, and the glaze water flows downward, and the mouth is thin along the glaze, or dry glaze, also known as "dry mouth". The bottom of the lamp is glazed and the outer wall is semi-glazed, so that the bottom of the lamp will not stick to the kiln during the firing process. There are many small holes in the inner tube of the sword lamp, which helps to keep the tea soup warm.
There is another saying about the magical effect of Jianzhan, that is, this small hole absorbs calcium and magnesium ions in the water, reduces the hardness of the water and makes the water soft. Cai Xiang also praised Jianzhan in the Book of Tea: "Tea is white and should be black. Jian' an is made of black, the lines are like rabbit hair, and the blank is slightly thicker ... It is difficult to cool after a long time of heat, and it is the most important to use. Those who go out from other places, whether thin or purple, are not as good as them. "
Second, the mouth is big and the bottom is small, and the tea fragrance is obvious.
A common building lamp is shaped like a funnel, with a shallow circle at the bottom and an opening. This pattern contains the wisdom of our ancestors. Funnel-shaped tea set is not only convenient for better observing the changes of tea soup during tea fighting, but also beneficial to the distribution of tea fragrance.
Third, preservation, not overnight deterioration.
On a hot summer night, the leftovers are put in a covered white bowl and a set of lamps respectively, and put in the kitchen cabinet. The leftovers in the built lamp can't be eaten the next day, and the leftovers in the white bowl have gone bad, giving off a sour taste.
Fourth, soften the water quality and improve the taste.
Drinking tea with spikes can keep warm and store heat for a long time and improve the alkalinity of tea soup. The quality of tea will become soft and sweet, which will stimulate and enhance the aroma of tea and ensure a better taste of tea. Therefore, drinking tea with a built lamp, boiling water with a iron pot and boiling water with a silver pot all have the same effect. Moreover, liquor, beer, red wine, boiled water, mineral water, coffee and other liquid drinks will taste more pure and delicious.
If you don't believe me, you can try comparing the same amount of hot water with a glass. If the hot water changes from hot to warm, the effect will be more obvious, as will other liquid drinks.
With these secrets, building a lamp will make tea lovers yearn for it.
