Glass cups have certain harmful effects on the human body. The main component of glass cups is ammonium aluminum sulfate. After placing a glass cup in the cup, it will not completely precipitate. There may be a small amount of aluminum powder floating on the surface of the cup. Long term consumption of such glass cups may have an impact on the body, such as osteoporosis, metal poisoning, gastrointestinal damage, etc.
1. Osteoporosis: The main component of a glass cup is ammonium aluminum sulfate. After placing a glass cup in the cup, there may be a small amount of aluminum powder floating on the surface of the cup. Long term consumption of such a glass cup may lead to excessive aluminum intake. Excessive aluminum intake can affect the synthesis of vitamin D, affect calcium absorption, and cause osteoporosis. It is recommended to choose a glass cup that does not contain aluminum as much as possible when drinking a glass cup;
2. Metal poisoning: Because the main component of glass cups is ammonium aluminum sulfate, if the cup is contaminated with aluminum products, it may lead to excessive intake of aluminum in the human body after use. Aluminum will bind with proteins in the human body, producing insoluble salts, which may cause metal poisoning and symptoms such as abdominal pain, nausea, and vomiting. In such cases, it is necessary to go to the hospital for examination and treatment in a timely manner;
3. Gastrointestinal injury: When using a glass cup to drink water, there may be a small amount of aluminum powder floating on the surface of the cup. Long term consumption of such glass cups may cause excessive aluminum intake, which can damage the digestive tract and lead to diseases such as gastritis and gastric ulcers. It is recommended to choose glass cups that do not contain aluminum as much as possible when using glass cups in daily life;
4. Other hazards: Due to the unstable aluminum element in glass cups, toxic gases may be released after severe impact, causing symptoms such as dizziness and vomiting in the human body. Therefore, it is not recommended to use glass cups for drinking water for a long time.
Whether a glass can be placed in a microwave depends on the type of glass.
If it is a regular glass cup or a tempered glass cup, it cannot be heated in the microwave because the former has poor heat resistance, and the latter contains metal components, which may explode when placed in the microwave. If it is a heat-resistant glass cup or a microwave heating specialized glass cup, it can be heated in a microwave oven. Both have undergone special treatment, have a small coefficient of expansion and good heat resistance, and are suitable for use in microwave ovens.
