- Observe the materials
Glass materials include soda-lime, tempered borosilicate, crystal(lead/lead-free) glasses, and it is safest to choose high borosilicate glasses.
2. Observe the thickness.
High-quality glasses, the thickness of the cup body is thicker, and the thickness of the bottom of the cup is thicker than the cup body, which is generally not easy to break and has a good heat resistance effect.
3. Observe transparency/transmittance
A good quality clear glass should be free of any impurities and no visible glass spots. Inferior glasses have poor light transmittance, blurry and impurities.
4. Observe bubbles.
A good glass is not allowed to have bubbles, if there are bubbles or there are more bubbles, it is generally poor materials/low process level, it is not.
5. Observe the roundness and thickness of the cup.
If it is not a special-shaped glass, check the roundness of the cup mouth and the bottom of the cup, whether it is perfectly round, the cup mouth is not round of the thickness is different, is not recommended to choose to buy.
6. Choose a double wall glass.
The double wall glass cup not only has a certain thermal insulation effect but also is not hot,easy to use, if the double wall glasses and the thermos cup have the same effect, don't believe it.
