Quartz glass is also called rock crystal.
Quartz glass, fused quartz is a single-component glass made of pure silicon oxide, obtained by melting natural varieties of silica - rock crystal, vein quartz and quartz sand.
Crystal (from ancient Greek κρύσταλλος - ice) is a special type of glass containing at least 24% lead oxide (PbO) or barium oxide (BaO).
The addition of lead oxide increases the refractive index of glass and the dispersion of light in it (from a jeweler's point of view - "play of color", "fire").
