Vermilion mud and purple sand are two different teapot materials, and there are obvious differences in their composition, origin, characteristics, and suitable people. Understanding these differences helps us better choose and use the right teapot for ourselves.
First of all, in terms of composition, vermilion is a clay with a high iron content, and the main components are silica, alumina and iron oxide. Purple sand is a special clay that contains minerals such as quartz, mica, and hematite. Due to the differences in these ingredients, there are also obvious differences between cinnabar and purple sand in terms of color, density, and air permeability.
Secondly, the origin of vermilion and purple sand is also different. Vermilion is mainly produced in Dingshan, Yixing, Jiangsu, while purple sand is mainly produced in Dingshu Town, Yixing, Jiangsu. Although the origins of both are in Yixing, Jiangsu, the difference between their origins is still obvious.
In terms of characteristics, the density of vermilion mud is high, it is orange-red or red after firing, the surface is grainy, and the feel is delicate and lubricated. The density of purple sand is low, and it is dark brown or purple-black after firing, with a sandy texture on the surface and a relatively rough feel. In addition, vermilion mud has good air permeability and is suitable for brewing green tea, yellow tea and other teas with a low degree of fermentation; The air permeability of purple sand is poor, and it is suitable for brewing black tea, Pu'er tea and other teas with a high degree of fermentation.
Finally, the applicable groups of vermilion and purple sand are also different. Due to the high density of vermilion teapots, it is easy to cause tea residues, so it is more suitable for experienced tea drinkers; The purple sand teapot, on the other hand, is more suitable for novices because it has relatively low requirements for tea-making skills.
In short, although vermilion mud and purple sand are both high-quality teapot materials, there are obvious differences in composition, origin, characteristics and suitable people. Understanding these differences can help us better choose and use the right teapot for us and enjoy our tea.
