25 Light crystal chandelier with Chrome finish and clear crystal. Bulb: Candelabra.
Full Lead crystal is lead glass that has been machine-cut with facets. Lead oxide added to the molten glass gives lead crystal a much higher index of refraction than normal glass, and consequently much greater "sparkle" by increasing specular reflection and the range of angles of total internal reflection. Ordinary glass has a refractive index of n=1.5, whereas the addition of lead produces a range up to 1.7. This heightened RI also raises the correlating index of dispersion, which measures the degree to which a medium separates light into its component spectra, as in a prism. The presence of lead also makes the glass softer and easier to cut. Crystal can consist of up to 35% lead, at which point it has the most sparkle. The higher lead content also makes it much more difficult to form crystal during manufacturing.
