I believe that the water cup is a necessary daily necessities in every family, after all, we have to drink water every day, and the water cup has become an indispensable item for us.
After all, water is the source of life, 60% of the components of the human body are water, and daily drinking water is an unavoidable topic for people, and it is also the point that people are most likely to ignore. We usually only care about the quality of water, but we ignore the container that holds the water.
In particular, CCTV has exposed the quality of the thermos cup before, and if the unqualified thermos cup is used for a long time, it will cause serious harm to our body.
So people have turned their attention to the glass, after all, it is a glass product, as long as it is cleaned, whether it is hot or cold water, it will not produce any harmful substances.
But glasses that have been fired at high temperatures are not necessarily absolutely safe. If we choose the wrong water cup, even if we drink boiled water, it is likely to become a cup of "poisonous water", which quietly endangers our health. So which cups are harmful, and which ones are safe and reliable?

High-quality crystal glasses
This kind of crystal cup is not made of crystal, but is made of 2%-30% minerals added to ordinary glass, and because it looks very close to natural crystal cups in terms of transparency and clarity.
In order to make the glass more beautiful and increase its transparency and refractive index, some manufacturers will add lead to the glass in order to make it look good. This method can indeed make the cup look crystal clear, but it can be harmful.
If this artificially made crystal cup is used to hold alcohol, carbonated drinks, acidic drinks, etc., the lead in the crystal products will seep out. And the longer the liquid is held, the higher the lead content in the liquid.
Lead can have a serious impact on vital human systems such as the nervous system and immune system, and if something goes wrong, the consequences will be irreversible, so this crystal cup just looks good, but it is not as safe as imagined.
Printed glasses
I believe that the printed glass is the favorite of children, and the children who are already full of childlike innocence will not be able to walk when they see this kind of printed water cup. However, the harm of this kind of printed glass to the body has irreversible damage, and many families have this kind of printed water cup.
When manufacturers make this kind of printed pattern, they need to use a lot of chemical and technological means to ensure that these patterns can be retained in the cup for a long time.
When children use this cup, there is irreversible damage to both the brain and the organs. Especially after the hot water, it will speed up the dissolution speed of the print, and the harm is self-evident.
Internet celebrity glacier cup
When we buy a cup, the first time is not to look at the material, but to look at the appearance of the cup. There is a kind of glass with gradient color on the Internet, which looks very good, and it is usually beautiful and safe to drink, and it also has a nice name "glacier cup".
But what looks good often has a huge potential threat, and the Glacier Cup is one of them. The color on the glacier cup is added to the glass through electroplating, spraying, etc., and the chemical elements and heavy metals used in this process will seriously exceed the standard, which will cause harm to our body.
Because this color is not inherent in the glass, every time you drink water, this harmful substance will gradually be drunk into the body, which will have adverse health effects.
In addition, the glacier cup has almost no transparency, so the flaws in the production are hidden in the cup. Many of them have a very unpleasant smell and small bubbles can be seen on the cup, which are all inferior products. Therefore, everyone should stay away early when they encounter the glacier cup.
Hazards of ceramic cups
The line water cup is also a relatively common drinking container in life, especially this kind of cup is colorful, different shapes, and hard texture, and it is also one of the many water cups with a sense of art and cultural atmosphere.
But this kind of water cup is no less harmful than a glass water bottle. Especially the colorful ceramic cups, the colored ceramic cups are usually coated with a layer of glaze, when encountering boiling water or acidic, alkaline drinks, aluminum and some other heavy metals and toxic elements in the glaze will appear, causing damage to our liver and other organs.
Moreover, the texture of the ceramic cup is relatively loose, and the surface is very easy to breed bacteria, which is not easy to plot, which increases the risk of bacterial infection. Among them, there are many small manufacturers for the benefit of the ceramic cup is not qualified, in order to be able to obtain benefits, can only continue to reduce the cost of production, such a ceramic cup itself has a certain danger, not to mention used to drink water.
How to choose a safe drinking glass
When buying a water glass, there are many things to pay attention to if you want to distinguish a toxic glass. One of the most intuitive points is to buy cups produced by big brands, which generally have a reputation and quality assurance, and if there is a problem, you can also complain.
If you buy three or five products because they are cheap, and there is really a problem, then you really can't cry. And there will be obvious labels in the products of big brands, emphasizing that they do not contain lead, so you must observe more when buying water bottles.
The second is that you can't buy bright cups, and the pigments used in this cup are basically "technology and hard work". When the cup is heated at a high temperature, the "semi-permanent material" on the surface of the cup is washed away with the hot water.
If you don't want a glass, for plastic cups, you can choose food-grade materials such as PETE1, PP5 or PC7. If you have a stainless steel mug, you should choose a product made of 304 or 316 stainless steel.
This type of thermos cup can be in direct contact with food, and the safety aspect is more reliable, especially the 316 stainless steel thermos cup, because of the addition of metal molybdenum, so it has absolute corrosion resistance.
In addition to choosing safe materials, we should also pay attention to the usual cleaning work, if there are often bacterial residues, the harm to the human body is not small, many people are rinsed with water, which is also a point that we are easy to ignore.
We have to drink water every day, but drinking water is not a simple thing, we must take it seriously, although the cup is a small container, but it plays an indispensable role in our lives, it is directly related to the safety of our lives.
