173: Midnight Blue

We start with a 1927 patent awarded to George Washington Carver, an agricultural chemist, for a locally-sourced Prussian blue. We learn a bit about Carver's life, education, and hobby of painting which may have led to the patent. We examine the patent in some detail, and then hear how it's been revived by a modern artist. Then we discuss other blue pigments throughout history, ending with the newest blue, an accidental discovery in a laboratory in 2009.Support the showSupport my podcast at https://www.patreon.com/thehistoryofchemistryTell me how your life relates to chemistry!
