Glass: practical safety anti-explosion
The first choice for drinking glasses should be glass, especially for office and home users. Glasses are not only transparent and beautiful, but the healthiest and safest among all materials. The glass is fired from inorganic silicates and does not contain organic chemicals during the firing process.
When people drink water or other beverages from a glass, they don’t have to worry about chemicals getting into their stomachs. Moreover, the glass surface is smooth and easy to clean, and bacteria and dirt are not easy to breed on the wall of the cup. So it is the healthiest and safest for people to drink water from a glass. But it should be noted that the glass is most afraid of thermal expansion and contraction. Do not pour hot water into a glass that is too low in temperature to prevent it from bursting.
Enamel cup: should be eliminated decisively after damage
Enamel drinking glasses are also a good option. Enamel is a composite material in which inorganic glass materials are melted and solidified on metal at thousands of degrees. Enamel coating on metal surfaces can prevent rust. When the metal is heated, it will not form an oxide layer on the surface and can resist the erosion of various liquids. Enamel products do not contain harmful substances such as lead, and are easy to carry and clean. Widely used as eating utensils and washing utensils used in daily life.
The enamel cup has a disadvantage. The enamel cup is afraid of bumping, and the surface is prone to damage. Studies have shown that damaged enamel cups are prone to precipitation of harmful substances when serving drinks, and should be eliminated decisively.
