CHE 209 Indigo: A World of Blues

Dip white fabric in the muddy-colored indigo dye vat and the cloth emerges green, then slowly turns azure, cobalt or sapphire before your eyes. The chemistry behind this reaction will be revealed-and practiced-in the course. This mysterious dye has an intriguing history, and we will study its societal and environmental impact. We will learn about the equipment used in producing indigo dye, and the three sources of indigo. The course culminates with the design of an indigo production facility. [STSC]
