Flint glass is optical glass that has relatively high refractive index and low Abbe number (high dispersion). Flint glasses are arbitrarily defined as having an Abbe number of 50 to 55 or less. The currently known flint glasses have refractive indices ranging between 1.45 and 2.00.

http://hyperphysics.phy-astr.gsu.edu/hbase/geoopt/glass.html WebCrown glasses have low refractive indices and low to moderate dispersions. The first flint glasses were potash-lead-silicate glasses prepared using English ‘flint’ as the source of silica. The presence of lead in these glasses results in higher refractive indices and dispersions than those of crown glasses. WebThe density of glass varies with each type and ranges from 2000 to 8000 kg/m 3 (for comparison, from less dense than aluminum to more dense than iron) at standard conditions. Flint glass can be so much denser than crown glass because flint glass contains lead, which is a very dense element. Shaye Storm -- 2004 flash-animation tutorial

WebHyperphysics. 2005. "Common crown glasses have indices of refraction around 1.5 to 1.6, while extra dense flint glass may have an index as high as 1.75." 1.5–1.6. Refraction is the change in direction of a wave due to a change in speed at the boundary between two media of different density. The Latin word "fract" in refraction means to break.
