In modern family life, glass has become the first choice for many consumers due to its transparency, beauty and easy cleaning. Among the many glass materials, crystal glasses is loved by more and more people for its crystal clear appearance and high-grade texture. But at the same time, many people are also concerned: Is it safe to drink water from crystal glass?
As a brand focusing on the manufacture of high-quality glassware, XINGHUO Glass will provide you with a comprehensive analysis of this issue from aspects such as material properties, production process, and health standards.
1. What is crystal glass?
"Crystal glass" is not glass made of natural crystal, but a glass material containing lead oxide (PbO) or other metal oxides (such as barium oxide, potassium oxide). It is named because of its high refractive index and good gloss, presenting a visual effect similar to natural crystal.
According to the different lead content, crystal glass can be divided into:
- Leaded crystal glass: The lead content is usually above 24%, with a thick texture and a steady feel, making it suitable for making high-end wine utensils, decorations, etc.
- Lead-free crystal glass: does not contain lead elements, and is replaced by other metal oxides, which also has good optical properties and environmental safety.
2. Is it safe to drink water from a crystal glass?
- Safety of lead crystal glass
Although leaded crystal glass contains lead, its structure is stable and it will not easily release lead at room temperature. However, if it is used to hold acidic beverages (such as juice, vinegar, carbonated beverages, etc.) for a long time, it may cause trace amounts of lead to precipitate, which poses certain health risks.
Therefore, XINGHUO Glass recommends:
Leaded crystal glass is more suitable for drinking water, boiled water or non-acidic beverages. It is not recommended to store acidic liquids such as juice, coffee, red wine, etc. for a long time.
In addition, there are strict international standards for food contact glass products, such as the EU's EN 1388-1/2 and the US FDA's relevant regulations. Crystal glass cups produced by regular manufacturers will pass relevant tests to ensure that they meet food safety requirements.
- Advantages of lead-free crystal glass
As consumers become more aware of health and environmental protection, more and more families are choosing lead-free crystal glass. This type of glass not only retains the transparency and beauty of crystal glass, but also avoids the potential risks brought by heavy metals, making it a safer and healthier option.
The lead-free crystal glass cups produced by XINGHUO Glass adopt advanced production technology and pass the national food-grade glass standard test. They are fully suitable for daily drinking, tea brewing and other scenarios.
3. How to judge whether the crystal glass is safe?
- Check the certification mark:When purchasing, you should choose products that have passed food contact material safety certification, such as: National GB 4806 Standard (China Food Contact Material Standard); FDA Certification (US Food and Drug Administration); LFGB Certification (German Food Grade Testing Standard)
- Observe product description:Crystal glass cups from regular brands will clearly indicate on the packaging or instructions whether they are "lead-free" or "low-lead", as well as information such as the applicable temperature range and usage recommendations.
- Sensory Discrimination:Listen to the sound: high-quality crystal glass will make a clear and pleasant sound when knocked. Look at the texture: crystal glass is more transparent and glossy than ordinary glass. Touch the edge: the cup mouth is smooth, burr-free, and comfortable to the touch.
