As he described in an 1866 essay, he obtained a transparent mass ''of a beautiful orange tending to red, reminiscent of the color of certain varieties of topaz, hessonite (kanel stone) and hyacinth (zircon) (5th Orangeroth 3/10, 9th Clay, Chevreul)''. The results of his experiments proved reproducible, but it was not until 1891 that Franz Welz of Bohemia acquired a German patent for the production of pink and orange glass using selenium.[1] Selenium was also used to decolorize the initially yellow-green glass mass. Depending on the composition of the glass mass, it colors red, orange, brown or pink. The terms ''selenium glass'' and ''rosalin glass'' are therefore not synonymous.[2]

The new glass color first appeared under various names such as ''salmon'', ''dull pink'', ''noble pink'' or ''aurora''. In the 1930s, rosaline glass, which was initially difficult to produce in view of the stability of the color, was offered by almost all pressed glass producers and increasingly became a fashionable color
