Cotton Blue 3 1/2
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 3-1/2.
