le of readily conforming to the various

2684. The Mordants.

For the reasons just given, the acetate or tartrate of iron is
preferable to the sulphate; and the acetate or tartrate of alumina to
alum. _For reds, yellows, green, and pinks_, aluminous mordants are to
be used. _For blacks, browns, puces, and violets_, the acetate or
tartrate of iron must be employed. _For scarlets_, use a tin mordant,
made by dissolving in strong nitric acid one-eighth of its weight of
sal-ammoniac, then adding by degrees one-eighth of its weight of tin,
and diluting the solution with one-fourth of its weight of water.

2685. Calico, Linen, and Muslin (Blue).

_Blue_.--Wash well to remove dressing, and dry; then dip in a strong
solution of sulphate of indigo--partly saturated with potash--and hang
up. Dry a piece to see if the colour is deep enough; if not dip again.

_Saxon Blue_.--Boil the article in alum, and then dip in a strong
solution of chemical blue.

2686. Calico, Linen, and Muslin (Buff).

_Buff_.--Boil an ounce of anatto in three quarts of water, add two
ounces of potash, stir well, and put in the calico while boiling, and
stir well for five minutes; remove and plunge into cold pump water,
hang up the articles without wringing, and when almost dry, fold.

2687. Calico, Linen, and Muslin (Pink).

_Pink_.--Immerse in the acetate of alumina mordant, and then in the
colouring of a pink saucer.

2688. Calico, Linen, and Muslin (Green).

_Green_.--Boil the article in an alum mordant, and then in a solution
of indigo mixed with any of the yellow dyes until the proper colour is
obtained.

2689. Calico, Linen, and Muslin (Yellow).

_Yellow_.

i. Cut potato tops when in flower, and express the juice; steep
articles in this for forty-eight hours.

ii. Dip in a strong solution of weld after boiling in an aluminous
mordant. Turmeric, fustic, anatto, &c., will answer the same as weld.

2690. Cloth (Black).

Impregnate the material with the acetate of iron mordant, and then
boil in a decoction of madder and logwood.

2691. Cloth (Madder Red).

Boil the cloth in a weak solution of pearlash--an ounce to a gallon of
water,--wash, dry, and then steep in a decoction of bruised nutgalls.
After drying it is to be steeped twice in dry
