Green with Prussian Blue

Dye a good Prussian blue (see No. 131) according to the depth of green required; then work 10 minutes in red liquor (see No. 100) at 40 Baumé; wash in warm water, and work for half an hour in a decoction of 3 pounds fustic; lift, and add 2 ounces alum in solution; work again for 10 minutes, wash and dry. A finer tint can be obtained by using bark instead of fustic, but it must not be worked too warm.
