Definition: crystal glass
Flint glass \Flint" glass`\ (Chem.)
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.
Note: The concave or diverging half on an achromatic lens is
usually made of flint glass.
