Glass Cup is the safest material for drinking cups. The glass is made of inorganic silicate after high temperature firing, the chemical composition is relatively stable, will not produce harmful substances. Its surface is smooth, easy to clean, and bacteria and dirt are not easy to breed. High borosilicate glass is more resistant to heat, wear and drop than ordinary glass. However, the glass is heavy and fragile, not suitable for carrying around, and may burst when heat expands and cold contracts. 12
Glass : Advantages include non-toxic, tasteless, chemical-free, heat and cold resistant, easy to clean and not easy to breed bacteria. The disadvantage is that the weight is large, fragile, not suitable for carrying out.
ceramic cup : the advantages are natural material, no chemical harm, beautiful and good thermal insulation effect. The disadvantage is fragile, easy to damage, need to be careful when cleaning, some ceramics may contain lead and other heavy metals.
Stainless steel cup : the advantages are corrosion resistance, high temperature resistance, lightweight and durable, good thermal insulation effect. The disadvantage is that inferior stainless steel may release harmful heavy metals and is not suitable for acidic substances.
Plastic cup : The advantages are light, affordable, colors and shapes. The disadvantage is that some plastic materials may release harmful substances at high temperatures, are not resistant to high temperatures, and are easy to deform.
When choosing a cup, use scenarios and personal preferences should be considered. For everyday household use, glasses and ceramic cups are good choices, especially glasses are highly respected for their high safety and easy cleaning. For portable occasions, stainless steel cups and some plastic cups (such as polypropylene PP and Tritan) are also good choices.
