Geskiendenis
In 1529, Georigius Agricola described the use of fluorspar as a flux.
In 1670 Heinrich Schwandhard found that glass was etched when exposed to fluorspar treated with acid.
In 1810, French scientist Andre-Marie Ampere proposed that fluoric acid was a compound of hydrogen with a new element.
The element was finally isolated in 1886 by Henri Moissan.
