The Galaxy 5, 1872
[Sheldon and Company, New York]
Antimony Blue is the name of a new color, much like ultramarine, but said to be more permanent. It is prepared by dissolving metallic antimony in nitro-muriatic acid, filtering through granulated glass, and adding to the filtrate solution of yellow prussiate of potash as long as any precipitate is formed. It promises to be very useful as a coloring for artificial flowers; and mixed with chrome yellow and zinc yellow it form fine greens, equal to those produced from arsenic, and much less poisonous. It also works well with oil varnishes, gums, glue, and starch, but is decomposed by lime. Boettger is the discoverer.
