Which toxic metal is often found in crystal drinking vessels, china, pewter, and paint?

• A. Lead
• B. Cadmium
• C. Mercury
• D. Arsenic

Answer: (A)

Lead is the toxic metal tied to all four items. In crystal glassware, lead oxide is added to increase density and refractive index, giving that characteristic bright sparkle. In ceramic glazes for china, lead compounds create a glossy, glassy finish and can affect color. Pewter historically included lead to improve malleability and workability. In paints, lead pigments like white lead or other lead-based compounds were widely used for durability and color. Because lead is highly toxic, exposure can be dangerous, especially for developing children, which is why modern products reduce or eliminate lead content.
