A Convenient Apparatus for Small-Scale Dyeing with Indigo
David W. Boykin
Delaware Technical & Community College, Biology/Chemistry Department, 400 Stanton-Christiana Road, Newark, DE 19713-2197

June 1998
Vol. 75 No. 6

Abstract
Small fabric strips can be dyed with indigo in a simple apparatus constructed from a 50-mL filter flask. The flask is charged with the dye bath and fabric, and it is closed with a stopper and a slit Pasteur pipette bulb over the side arm. When the bath is heated, the slit safely equalizes the pressure and minimizes exposure of the leucoindigo to air. The amount of reducing agent required and the odor produced are significantly less than with open dye-bath containers.
