What is leaded crystal and lead-free crystal? Why is lead-free crystal become so important

Leaded vs. Lead-free crystals: a battle and choice for transparent beauty

 In the world of crystals, leaded and lead-free crystals are two common materials, each exuding a unique charm and triggering consumer consideration between aesthetics and health and safety. This article takes an in-depth look at the differences between leaded and lead-free crystals, including their composition, characteristics, advantages and disadvantages, and how to make an informed choice.

 Ingredients and Characteristics

 Lead crystal, as the name suggests, is characterized by a high percentage of lead oxide (PbO), usually around 24% or above 24%. The addition of lead oxide gives crystals an extremely high refractive index and a sparkling effect, making lead crystal products look even more crystal clear and brilliant. This material is often used to make decorative items and artwork, and is favored for its unique optical properties.

 Lead-free crystals, on the other hand, are crystal products that contain no lead or only trace amounts of lead (usually less than 1%). In order to achieve a visual effect similar to that of lead crystals, lead-free crystals usually use other metal oxides such as potassium, barium and zinc as additives. While these crystals may be slightly less transparent and lustrous, their environmental friendliness and safety have become their biggest selling points.

 Safety and Health Considerations

 The safety of lead crystal has always been a concern. Although the amount of lead released from lead crystal under normal use is not sufficient to cause immediate and significant harm, prolonged exposure or improper use (e.g., storing acidic beverages) may result in the release of trace amounts of lead, which in turn increases the risk of lead poisoning, especially for children and pregnant women who are more sensitive. Lead poisoning can cause neurological damage, anemia, and growth disorders.

 Lead-free crystals, on the other hand, greatly reduce the aforementioned health risks due to their low- or no-lead characteristics, and are especially suitable for daily use in the home, especially for families with children. It ensures aesthetics while paying more attention to product safety and environmental protection, which satisfies modern people's pursuit of a healthy life.

 Environmental Protection and Sustainability

 From the perspective of environmental protection and sustainable development, lead-free crystals are undoubtedly a better choice. With the global awareness of environmental protection, many countries and regions have begun to restrict or ban the production and sale of lead-containing products. The promotion of the use of lead-free crystal not only reduces environmental pollution, but also promotes the green transformation of the crystal products industry.
