Step 1: See if the workmanship of the glass is fine. The exquisite processing technology can ensure the purity and transparency of the glass body.
Step 2: Pay attention to whether there are cracks in the inner and outer layers of the glass. Cracked glasses are easy to burst after hot water is injected, which may burn yourself, so be sure to carefully observe whether there are cracks in the glass body when choosing a glass.
Step 3: Bring the cup closer and smell it. Generally speaking, glass has almost no smell. Even if some cups have a taste, they will be washed with boiling water once or twice, so I am not very worried about this.
Is the glass cup poisonous?
At present, there are two kinds of crystal glass circulating in the market: lead-free crystal glass and lead-containing crystal glass. The former generally contains potassium, mostly high-grade handicrafts and marked on the outer packaging; The latter contains lead, that is, crystal glassware common in some supermarkets and stalls, and its lead oxide content can reach 24%.
In daily life, when a cup made of artificial crystal containing lead is used to hold acidic drinks, such as alcohol, cola, honey, fruit juice containing fruit acid or other acidic foods. Lead ions may form soluble lead salts, which are ingested by the human body with drinks or food, seriously endangering health.
