Among all the water bottles of the material, the glass water bottles are the healthiest. Glass water bottle does not contain organic chemicals in the firing process, and the glass surface is smooth, easy to clean, bacteria and dirt are not easy to breed in the glass wall, so people drink water with glass water bottle is the healthiest and safest.
Plastic water bottles should also be unpopular. Because plasticizers are often added to plastics, which contain some toxic chemicals, when hot water or boiling water is filled in plastic water bottles, toxic chemicals can easily dilute into water, and the internal micro-structure of plastics has many holes, which hide dirt, and it is easy to breed bacteria if it is not cleaned properly. Therefore, when choosing plastic water bottles, it is necessary to choose water bottles made of edible grade plastics that meet the national standards.
Although the glass water bottles does not contain chemical substances and is easy to clean, it is easy for users to blanch themselves inadvertently because of its strong thermal conductivity. If the water temperature is too high, it may cause the glass water bottles to burst, so it is necessary to avoid filling hot water as far as possible. Metal cups, such as stainless steel, are more expensive than ceramic cups. The metal elements contained in the enamel cup are usually stable, but they may dissolve in acidic environment. It is not safe to drink acidic drinks such as coffee and orange juice.
Colorful cups are attractive, but it's better not to use them. Because there are huge hidden dangers in those bright pigments, especially glazed inner walls. When cups are filled with boiling water or drinks with high acidity and alkalinity, toxic heavy metal elements such as lead in these pigments are easy to dissolve in liquids. When people drink liquid with chemical substances, it will cause harm to human body.
