Why does Princess House crystal have a 24% lead content?

The 24% lead content is a recognised standard for high-quality crystal. European regulations often define lead crystal as containing at least 24% lead oxide. This level enhances clarity, making the glass more transparent. It also allows artisans to cut detailed patterns into the surface. Princess House adopted this standard to align with traditional European crystal-making methods. The result is a product that reflects light more effectively than ordinary glass. This feature became one of the brand’s key selling points during the 1960s and 1970s.
