2581. To Dye with Aniline Crimson

2581.    To Dye with Aniline Crimson. A solid dye, belonging to the same series as the preceding, is sold as crimson, but it does not appear to differ very materially from magenta, giving shades with a trifle less blue. It is applied in the same manner as magenta. (See Nos. 2575 (To Prepare Magenta for Dyeing), etc..) Much better colors are obtained by the use of aniline yellow (see No. 2579 (To Dye Aniline Yellow)) and magenta. The former may be applied in the manner indicated for that color, and the fabric so dyed must be passed through

ANILINE COLORS, a bath of magenta until the required shade is produced. By mixing the liquid yellow and magenta dyes in a bath of soap-suds, nearly every shade from magenta to orange may be obtained. This will be found a satisfactory method for amateurs.

2582. To Prepare Aniline Scarlet Dye

2582. To Prepare Aniline Scarlet Dye. To produce this color, aniline scarlet dye may be used. Neither this nor coralline is adapted for amateur use, as great exactness is required in compounding the dye bath. For the use of amateurs, aniline yellow and magenta, as indicated for crimson (see No. 2581 (To Dye with Aniline Crimson)) is recommended. To produce scarlet the yellow should predominate, or the bath may be rendered slightly sour by sulphuric acid. Aniline scarlet dissolves easily in water, and the bath may be made directly from the 6olid substance. A liquid dye may be made, if desired, by dissolving 1 pound scarlet in 4 gallons water and 1 gallon alcohol.

This solution has to be filtered before being added to the bath. The goods remain in the latter for 15 minutes, when they have become browned, and must be boiled for another half hour in the same bath, after the addition of sal ammoniac. The more of this is added the redder the shade will become.
