Whether a fake purple casserole is toxic
Are the chemicals contained in the “purple clay pot” row harmful to health? In food safety knowledge, manganese dioxide, nickel oxide clauses chemicals and other materials have some toxicity data, but in food added equipment, whether it is harmful to the human body, experts express firm dose toxicity.
Purple clay products are composed of four steps: raw material formulation, refining, forming and firing, and purple sand grains with different colors and luster are selected from the purple clay made by refining, and then infiltrated into the purple clay mud after calcination, crushing, and sifting, and then mixed into the purple clay required for molding. The purple casserole pot and various tea utensils produced have good air permeability, and the tea can be brewed for many days, and the appearance of purple clay products is lustrous and beautiful.
Identify the authenticity of the purple casserole
Look at the color: the color of pure purple sand, whether purple, yellow, red or the color between the two should have a jade-like charm, its light quality is a dark light, like oil, the more rubbed the more moist, can not be waxed, can not be polished, can refer to the material effect of old jade, the rarer the material, the more valuable, because of limited resources.
Look at the feel: Zisha’s hand sensor is smooth and round, comfortable, although there are particles but very round.
A real purple clay utensil should be pure in color, uniform in particles without impurities and blemishes, even if it is “clay” and “granular skin”, each of its colors should be very pure. That color is dirty and full of impurities, and the burrs must not be good mud. Without good mud, its craftsmanship level must be very poor. To be precise, the craftsmanship value of purple clay pottery (or price, in Marx’s theory, price and value are two completely different concepts) is completely determined by its level of craftsmanship. In layman’s terms, it’s workmanship.
