Which is better, a steamer or a steamer? Which color will turn black?

1, manual steamer, mainly about workmanship (all products are the same, good workmanship and good quality) 2, there is not much difference between the two kinds of bamboo. Kind bamboo leaves also have the effect of clearing away heat. The master who makes a steamer usually removes the green skin of bamboo. Because the green husk is hard, it will take a long time to make it if it is not removed, as if it must be baked soft. In many places, bamboo is divided into thin bamboo pieces. This kind of steamer is light and easily damaged. Sichuan is the main producing area of Cizhu, and most of the steamer is made of Cizhu. But there are also two kinds, those with green skin and those without green skin. The steamer with green husk needs baking, so the price is more expensive (but mainly depends on the workmanship, and the poor workmanship is cheaper). 6. Phyllostachys pubescens, also known as Phyllostachys pubescens, is the main material of the steamer. Because it is easy to process, it is convenient to make a steamer and the cost is low. The price of mass-produced steamer in Guangdong and Fujian is only about 10 yuan. 7. Color change of the steamer: If the outer skin is green, it will turn brown with the increase of use time, and the longer the use time, the better the color. And those without green skin will gradually turn black. Just like chopsticks. The picture below shows the color contrast of the steamer with and without green skin.
