1、壶盖。壶盖有平形和弧形两类。同时盖分有盖舌与无盖舌两种。如果是使用过的壶,在壶的盖舌外沿就会留下茶垢,茶垢的厚度基本与壶内的茶垢相当,因为每次泡茶盖盖时,盖舌总是浸在茶汁内。如果壶盖是平的,又没有盖舌的盖,盖的内壁也会有茶垢,但是茶垢要比盖舌、壶内要淡得多。 1, lid. Lid has a flat and curved two types. At the same time, there are two types of flap-type flap and flapless flap. If it is used in the kettle, the outer edge of the tongue will leave tea kettle scale, the basic thickness of tea scale and tea pot fairly, because every time the lid is covered, the tongue is always immersed in tea Juice inside. If the lid is flat, there is no lid flap, cover the inner wall will have tea scale, but the tea scale than flap, the pot to much lighter.
