Cotton Blue


This 30 ml glass bottle contains synthetic alizarin. 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 often red , but this sample is termed Cotton 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.
