The following recipes will serve to ill.u.s.trate 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 quant.i.ties 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 F., enter an equal quant.i.ty 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 or 130 F., then work an hour longer. Another black can be dyed in a similar way from 5 lb. Victoria Black B, 10 lb. Glauber"s salt, and 2 lb.
sulphuric acid.
_Violet_.--Use 2 lb. Acid Violet 5 B, or 2 lb. Formyl Violet S 4 B, 10 lb. Glauber"s salt, and 2 lb. sulphuric acid. Fast Acid Violet 10 B gives a bluer shade than the above.
_Green_.--Make the dye-bath with 2 lb. Acid Green G G, 10 lb. (p. 192) Glauber"s salt, and 2 lb. sulphuric acid, working at the boil. This gives a bright yellow shade of green; a bluer shade can be got from Acid Green 6 B or Acid Green B, while Fast Green Bluish gives very blue greens.
_Coeruleum Blue_.--Dye with 3/4 lb. Silk Blue B E S, 10 lb. Glauber"s salt, and 2 lb. sulphuric acid; this gives a very fine bright blue.
_Deep Indigo Blue_.--Dye with 4-1/2 lb. Solid Blue R, 2 lb.
Thiocarmine R paste, 10 lb. Glauber"s salt and 2 lb. sulphuric acid.
_Deep Violet Brown_.--Dye with 3 lb. Croceine A Z, 1-1/4 lb. Indian Yellow, 1-3/4 lb. Formyl Violet S 4 B, 10 lb. Glauber"s salt, and 2 lb. sulphuric acid for an hour at the boil, and for an hour at 120 F.
_Blue Black_.--Make the dye-bath with 5 lb. New Victoria Blue Black, 10 lb. Glauber"s salt, and 2 lb. sulphuric acid, working at the boil.
Another plan is to use 5 lb. Naphthylamine Black 4 B and 10 lb.
bisulphate of soda.

Naphthol Green B, 1 lb. Amaranth, 10 lb. Glauber"s salt, 8 lb.
copperas, and 3 lb. sulphuric acid, working at the boil for an hour and then rinsing in water to which a little acetate of ammonia has been added. The silk is dyed grey and the wool a black.
_Brown_.--A fine yellow brown shot with lilac is obtained by first dyeing in a bath of 5 lb. Naphthol Yellow, 10 lb. Glauber"s salt and 2 lb. sulphuric acid. Wash in hot water, then dye with 2-1/2 lb. Solid Blue P G, 1-1/2 oz. Methyl Violet B O, and 5 lb. acetic acid in the cold.
_Wool, Orange; Silk, Pale Green._--Dye the wool with 1-1/2 lb. Orange G G, 6 oz. Naphthol Green B, 2-1/2 oz. Naphthol Red C, 10 lb.
bisulphate of soda, and 2 lb. sulphuric acid; and the silk with 1/2 lb. Milling Yellow and 1/2 lb. Acid Green.
_Wool, Black; Silk, Light Grey._--Dye in a bath with 5 lb. (p. 193) Anthracene Acid Black S T, 4-1/2 oz. Fast Yellow S, 10 lb. bisulphate of soda, and 2 lb. sulphuric acid. The silk is cleaned by boiling for ten minutes in a soap bath.
_Wool, Bright Red; Silk, Blush Rose._--The gloria silk is dyed in a bath of 3 lb. Naphthol Red O, 10 lb. bisulphate of soda, and 2 lb.
sulphuric acid. After dyeing, soap for ten minutes.

Anthracene Acid Black S T, 5 oz. Fast Yellow S, 2 lb. oxalic acid, 10 lb. Glauber"s salt, and 15 lb. acetic acid. Work the goods in this at the boil for an hour, then lift, add 3/4 lb. bichromate of potash, and boil for twenty minutes longer. Clean the silk by boiling in a bath of soap for twenty minutes, then dye in a cold bath containing 1 lb. Thioflavine T and 1 lb. Brilliant Green.
_Wool, Dark Maroon; Silk, Pale Blue._--After the manner described in the first recipe, dye the wool with 1 lb. Orange G G, 3 lb. Naphthol Green B, 2 lb. Brilliant Cochineal 2 R, 10 lb. bisulphate of soda, and 2 lb. sulphuric acid. Dye the silk with 1-1/2 lb. Pure Blue O T.
_Wool, Violet; Silk, Green._--Make the dye-bath with 1 lb. Acid Violet 4 B, 9 oz. Indigotine extra, 10 lb. bisulphate of soda, and 2 lb.
sulphuric acid. The dyeing is carried on at the boil until the bath is exhausted of colour, whereupon the goods are well rinsed in water.
They are next soaped at 160 F. for ten minutes in a liquor containing 1/2 oz. soap per gallon, then rinsed. Next a dye-bath is made with 1 lb. Acid Green, 8 oz. Milling Yellow O, and 1 lb. acetic acid, the goods being treated in this in the cold until the desired shade is obtained, then lifted, rinsed and dried.

_Brown Olive and Green_ is dyed in a bath made with 1 lb. (p. 194) Quinoline Yellow, 1 lb. Azo Fuchsine G, 1/4 lb. Fast Green Bluish, 10 lb. Glauber"s salt, and 2 lb. sulphuric acid. By using about half the above quant.i.ties of dye-stuffs a drab effect shot with green can be obtained.
_Crimson and Green._--The first bath is made from 4 lb. Azo Red A and 10 lb. bisulphate of soda, worked for an hour at the boil; then treat in a weak bath of acetate of ammonia; and dye the silk in a cold bath of 2 oz. Solid Green Crystals, 1/4 lb. Thioflavine T, and 5 lb. acetic acid.
_Violet and Pink._--Dye in a bath of 1-1/4 lb. Indigo extract, 10 lb.
Glauber"s salt and 2 lb. sulphuric acid.
_Brown and Pink._--This is dyed in a bath made from 1-1/4 lb. Fast Yellow, 5 oz. Rhodamine B, 1/4 lb. indigo extract, 10 lb. Glauber"s salt, and 2 lb. sulphuric acid. The silk dyes a pale pink while the general effect is that of a fine fawn brown with a reddish shot effect.
_Dark Green and Pale Crimson._--This is done in two baths, the first is made with 8 lb. Naphthol Green B, 10 lb. Glauber"s salt, 3 lb.
sulphuric acid, and 7 lb. copperas, working at the boil; then treat with hot water and dye in a fresh bath with 6 oz. Safranine Prima and 5 lb. acetic acid in the cold. The combined effect of the two is that of a brown shot with green.
_Orange and Green._--This gives a splendid shot effect and is dyed as follows. Work for an hour at the boil, for thirty minutes in a bath of boiling water, then enter into a cold bath of 5 oz. Thioflavine T, 3 oz. Brilliant Green, and 3 lb. acetic acid; work for thirty minutes, or until shade is obtained.
