Usage conditions apply
Alizarin, a natural dye derived from the root of the madder plant, has been used for many years. This 30 ml. glass bottle contains synthetic alizarin, the first organic colorant to be synthesized. in 1869. The "Wm. Pickhardt & Kuttroff, New York" inscription refers to a dyestuff firm that was established in 1861, and that became the Continental Color and Chemical Co. in 1906. Alizarin is usually red (and known under such names as Mordant Red or Turkey Red). This sample, however, is blue.
This sample was probably part of the Loeb Collection of Chemical Types, a collection that was formed under the bequest of Morris Loeb (1863-1912), a Jewish-American chemist and philanthropist, and sent to the Smithsonian in 1920.
