On woolen goods, boil the goods, which must be well cleaned, in a boiler along with some of the sulphate of indigo and fustic. - Yarn must be well turned in the liquor and cloth well stirred. The depth of shades depends on the quantity of indigo used. The fustic must be added or diminished according to the yellowness of the shade wanted. About a pound of fustic to a pound of goods, is about enough for a common shade. The sulphate of indigo is made by adding the flour of indigo of the best quality, to vitriol, about 1lb. of indigo to the 5 of vitriol and adding gradually for two days stirring frequently at the same time. The sulphate of indigo should never be used before it is nine days old. It is worth twice as much after this time, as it would be if used before. A little alum is added to the woolen cloth. The sulphate of indigo will dye many shades of blue.
Green on silk is dyed with the same stuffs as wool, or woolen goods, only not boiled, and a little quantity of turmeric used. It is requisite to dye at a good heat.
Green on cotton, is dyed by dipping the goods first in a blue vat, then washing them and pressing them, and then running them through a solution of sugar of lead and afterwards through a solution of the bichromate of potass airing them and running through the lead again. Three parts of the lead to one of the chrome are the proportionate quantities. —The sulphate of zinc and litharge are also used as mordaunts. The depth of color is regulated by the darkness of the blue. All goods should be well washed for finishing. Any person can soon hit the depths of shade by practice, if they have an eye for colors.
Another method : After the goods are dyed blue, wash them, run them through pyroligneous acid pretty strong, wash them and run them through a solution of Quercitron bark, at the rate of 4 lbs. of bark to 10 lbs. of cotton. The quantities always in proportion to the depth of the shade.
Another method, and one good for carpet rags, and with which every housewife ought to be acquainted : Scald about two pounds of ground logwood and boil about five pounds of fustic well ; take the clear of this and put in about 4 ounces of the sulphate of copper, (blue vitriol,) and keeping the liquor at a good heat for some time, it will dye ten pounds of cotton carpet rags and twenty pounds of woollen carpet rags, a good dark green. This is cheap and easy dyed color.
These colors may be depended on. They are not receipts that will not operate as described—we have tested them. The woolen green is not a pure fast color though.
