Medical Definition of Flint glass

1. 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. Synonym: crystal glass. Cf. Glass. The concave or diverging half on an achromatic lens is usually made of flint glass. Source: Websters Dictionary (01 Mar 1998)
