Flint Glass

Webster's Dictionary

A soft, heavy, brilliant glass, consisting essentially of a silicate of lead and potassium. It is used for tableware, and for optical instruments, as prisms, its density giving a high degree of dispersive power; - so called, because formerly the silica was obtained from pulverized flints. Called also crystal glass. Cf. Glass.
