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? Here are a few tips for everyone. To identify the true and false purple casserole, you need to look at the following three kinds.
Look at the color first.
Color is the first impression. Purple sand is rich in color, except chestnut purple, 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 and generally clear. Look carefully, there is a feeling of yellow mud. In addition to a lot of purple, purple casserole also has green, yellow, black and so on. It can be said that the colors are different and the products are different.
Second, look at the feel.
Because purple mud contains a considerable proportion of sand, the purple casserole made of non-purple mud looks smooth, but it feels astringent in the hand, but the high-quality purple casserole feels comfortable and gentle with the skin. 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 hand-made, the mud is hammered many times, and then the producer has many processes. The fingerprints on it can be described as thousands of times, and the knocking sound is crisp after firing. When the fake purple casserole is shaped, it is only made of mud that is spun out of the turntable or made of a model. The mud has not been pushed, pinched, touched and scraped by artists, so it lacks rhyme and makes the tapping sound dull.
