Purple casserole is made of purple sand, which is rich in trace elements, supplements iron and blood, and is good for health. It is a proud assistant for ordinary consumers to cook soup and rice. But now there are fake purple casseroles on the market, which are not entirely pure purple sand, but made of ordinary clay such as loess and black soil, and added with chemical pigments such as iron red powder and manganese dioxide. Therefore, many consumers flinch from purple casserole and worry whether it will harm their health. So what's the difference between true and false purple casserole? How can I buy a truly reassuring product? Today, Bian Xiao, the porcelain library, will give you a few tips. To identify the true and false purple casserole, you need to look at the following three kinds. First, look at the color is the first impression, purple sand is rich in color, besides chestnut purple, there are red purple, brown purple, black purple and so on. In other places, the so-called purple mud burned by finished products is single in color, usually orange. Look carefully, there is a feeling of yellow mud. In addition to a large number of purple, purple casserole also has green, yellow, black and other colors. It can be said that the color is similar, and there is no product.

Because the purple clay contains a considerable proportion of sand, the purple casserole made of non-Yixing purple clay looks smooth, but it feels astringent in the hand, but the feeling of good quality purple casserole in contact with the skin is comfortable and gentle. Some fakes feel very delicate and smooth, and sometimes they shine. This is because this product is often polished mechanically during processing to deceive consumers. Third, listen to the sound. Purple casserole is made by hand, and the mud has been hammered many times. * * *, and then the producer has many processes. The fingerprints on it can be said to be tens of millions of times. After firing, the knocking sound is crisp. When the fake purple sand casserole is shaped, it is only made of mud by spinning it out of the turntable or using a model. Mud has not been squeezed, nor has it been pushed, pinched, touched, wiped or scraped by artists. (Editor: Chen Ling)
