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.
