Crystal foods harmful to the human body?

Colorful crystal containers often cause consumers to have a strong desire to buy. So, will these beautiful crystal products endanger our health?

The answer is yes, because the content of lead oxide contained in crystal products is as high as 20%-30%, so when we use it to hold water, no chemical reaction occurs, but when we use it to hold wine, crystal products Lead will be dissolved in wine, and the longer the time, the more dissolved. Similarly, when crystal products are used to hold foods, especially acidic foods such as cola, honey, and fruit juices, lead ions are also prone to form soluble lead salts, which are ingested by humans as a result of beverages or foods, thus seriously endangering health. Therefore, crystal glass products have been called "beautiful killers" by scientists. Therefore, identifying leaded crystals and non-leaded crystals is a place worthy of our understanding.

Experts suggest that the purchase of crystal glass tableware can distinguish ordinary glass, lead crystal glass, and lead-free crystal glass by sound, feel, and appearance. Ordinary glass products are dull in color, poor in refractive index, rough in workmanship, and have poor feel. There are even bubbles in some places, and the sound is lightly tapped. Crystal glass products are lighter in color than ordinary glass products, have a high refractive index, are exquisitely crafted, and have a good feel. They look like crystals and gently strike a crisp metallic sound. Lead-free crystal glass products are slightly thicker than lead-free crystal glass products. In addition, the same volume, shape, size, two lead-free crystal glass and lead crystal glass, lead-free crystal glass lighter.
