ous by their
fewness. On the other hand, the dyer has in the blue and yellow dyes
from coal tar a means of producing any tint or shade of green he may
require.
Members of all the classes of basic, direct, acid, azo and mordant
dyes, can be found among the dye-stuffs which can be used in dyeing
green, and the methods and principles of their application have been
fully described in previous pages. The following recipes contain all
the practical information that is needed:--
#With Direct Dyes.# _Dark Green_.--The dye-bath is made with 1 lb. Titan
Blue 3 B, 1 lb. Titan Yellow Y, 2 lb. salt, and 1/2 lb. acetic acid.
_Bright Green_.--Prepare a dye-bath with 1 lb. Titan Yellow G, 1 lb.
Titan Blue 3 B, 20 lb. salt, and 1/2 lb. acetic acid, working at the
boil for one hour.
_Dark Green_.--Make a dye-bath with 4 lb. Acid Blue 4 S, 2 lb. Titan
Yellow Y, and 5 lb. acetate of ammonia, working at the boil to shade.
_Blue Green_.--Make the dye-bath with 6 lb. Acid Blue 4 S, 2-1/2 lb.
Titan Yellow Y, and 5 lb. acetate of ammonia, working at the boil to
shade.
_Bottle Green_.--The dye-bath is made with 5 lb. Acid Blue 4 S,
2-1/2 lb. Titan Yellow Y, and 5 lb. acetate of ammonia, working at the
boil to shade. The greens shown in the last three recipes are of a
very satisfactory character, and show how, by the use of acetate of
ammonia in the dye-bath, the direct dyeing Titan colours can be
combined with acid colours.
_Green_.--Make the dye-bath with 5 lb. Glauber's salt, 5 lb. (p. 128)
acetate of ammonia, 2 lb. Sulphon Cyanine, and 1-1/2 lb. Chrysophenine.
_Dark Green_.--The dye-bath is made with 2 lb. Sulphon Cyanine,
3/4 lb. Chrysophenine, 5 lb. Glauber's salt, and 5 lb. acetate of
ammonia.
_Pale Russian Green_.--Make the dye-bath with 1/2 lb. Sulphon Cyanine,
2-1/2 oz. Chrysophenine, and 10 lb. Glauber's salt.
The last three shades have the merit of being fast to milling, and
fairly so to light.
_Olive_.--Make a dye-bath with 1 lb. Nyanza Black B, 1 lb. Chrysamine,
and 20 lb. Glauber's salt. Work at the boil to shade, lift, wash and
dry.
#With Acid Dyes.# _Blue Green_.--Make a dye-bath with 10 lb. Glauber's
salt, 2 lb. sulphuric acid, 2 lb. Patent Blue N, and 1 lb. Azo Yellow,
working at the boil.
_Sage Green_.--The dye-bath is made with 10 lb. Glauber's salt, 2 lb.
sulphuric acid, 2 lb. Azo Yellow, and 1 lb. Patent Blue N, working at
the boil.
_Olive Green_.--Make the dye-bath with 3 lb. Naphtho
