Alkali Blue and Nicholsons Blue
Dissolve 1
pound of the dye in 10 gallons boiling water, and add this by small portions
to the dye bath: which should be rendered alkaline by borax. The fabric
should be well worked about between each addition of the color. The
temperature must be kept under 212° F. To develop the color, wash with water
and pass through a bath containing sulphuric acid. |
