Cotton Blue No. 6
notes: label: Description
content: Alizarin, a natural dye derived from the root of the madder plant, was used for many years before 1869 when it became the first organic colorant to be synthesized. The "Wm. Pickhardt & Kuttroff, New York" inscription on this 30 ml glass bottle containing synthetic alizarin refers to a dyestuff firm that was established in 1861, and that became the Continental Color and Chemical Co. in 1906. Alizarin is often red, but this sample is Cotton Blue No. 6.

content: 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.
