Gloria may be dyed either by a one-bath or two-bath process, and
either one or two colours, as may be required. In both cases advantage
may be taken of the different affinities of the two fibres for the
dye-stuffs used, as, for instance, the silk may be dyed brown, the
wool olive by using a mixture of Acid Yellow, Indigo extract and
Orange G. Indigo extract, Cochineal, Acid Magenta, Picric acid,
Naphthol Yellow, and Tartrazine dye the wool only at the boil.

The following recipes will serve to illustrate the foregoing remarks
and show how this important fabric may be dyed:--

_Deep Gold_.--The dye-bath is made from 2 lb. Indian Yellow, 10 lb.
Glauber's salt, and 2 lb. sulphuric acid, dyed at the boil. In this
and following recipes the quantities are for 100 lb.

_Orange_.--The dye-bath is made with 2 lb. Indian Yellow, 19 lb. (p. 191)
Glauber's salt, and 2 lb. sulphuric acid.

_Scarlet_.--Make the dye-bath with 2 lb. Scarlet 3 R, 10 lb. Glauber's
salt, and 2 lb. sulphuric acid. Another scarlet is got from 2 lb.
sulphuric acid. Another scarlet is got from 2 lb. Croceine Scarlet
3 B, 2 lb. sulphuric acid, and 10 lb. Glauber's salt; by using the 5 B
Scarlet a bluer shade can be dyed. Azo Cochineal also dyes a fine
scarlet on gloria.

_Crimson_.--Make the dye-bath with 1 lb. Carmoisin B, 10 lb. Glauber's
salt, and 2 lb. sulphuric acid. The 7 B Croceine Scarlet also dyes a
fine crimson of a more fiery tone than the last, while 2-1/2 lb. Azo
Fuchsine G dyes a bluer shade of crimson.

_Rose_.--A fine rose is obtained with 2 lb. Rhodamine B, 10 lb.
Glauber's salt, and a little acetic acid. 1 lb. Phloxine dyes a fine
deep rose; the silk comes out a paler colour than the wool, but the
general effect is good.

_Deep Maroon_.--Make the dye-bath from 1-1/2 lb. Croceine A Z, 1/2 lb.
Indian Yellow, 1/4 lb. Formyl Violet S 4 B, 10 lb. bisulphate of soda.
Enter the goods, work at the boil for an hour, then cool down to
120 deg. F., enter an equal quantity of dye-stuff and work for an hour
longer.

_Pale Maroon_.--Make the dye-bath with 3 lb. Azo Bordeaux, 10 lb.
Glauber's salt and 2 lb. sulphuric acid.

_Black_.--Prepare the dye-bath with 5 lb. Naphthylamine Black D, 1 lb.
Acid Green B, 10 lb. Glauber's salt, and 2 lb. sulphuric acid; work at
the boil for twenty minutes, then allow to cool to 120 deg. or 130 deg.
F., then work an hour longer. Another black c
