214. Properties of Dye-woods

214.    Properties of Dye-woods. Peach-wood reddens, madder gives the drab tint, fustic supplies yellowness, and logwood induces a slate hue.

215. Stone Drab

215.    Stone Drab. "Work the goods for 20 minutes in a bath containing 1 ounce peachwood or limawood, 2 ounces logwood and 1/2 ounce fustic; lift, and add 1 ounce copperas in solution; stir well and work in this for 30 minutes'; lift out and expose to the air for a short time; wash and dry. Different shades are made by varying the quantities of the dye-woods. (See last receipt!)

216. Slate

216.    Slate. Work for half an hour in a bath with 8 ounces logwood and 1 ounce fustic ; lift, and add 1 ounce alum and 1/2 ounce copperas in solution; work for half an hour; wash and dry. For a bluer tint, use less alum and more copperas; for more purple, use less fustic and more alum, etc..

217. Blue

217.    Blue. Dyeing woolens blue is performed by dipping in the blue vat (see No. 130 (Indigo Blue Dye for Yarn)), and then exposing to the air, repeating the operation till the desired depth of color is obtained.

218. Blue Purple

218.    Blue Purple. 100 pounds wool are first dipped a light blue in the vat, and well rinsed. Then take a stone pot, put in 3 pounds tartar, 3 pounds feathered tin, 5 pounds blue vitriol, and 20 pounds muriatic acid; heat all in a sand bath until dissolved.

From this mordant take 10 pounds in a suitable kettle; add 5 pounds tartar to it, stir it well, and enter the wool at 170° Fahr.; let it boil for 1 hour; take it out, cool, and let it lay for 24 hours. Then boil out 20 pounds good logwood for 3/4 hour in fresh water; cool off the kettle to 150° Fahr., enter the wool, and handle it well for an hour, then heat it up to 185° Fahr., but do not let it boil; let it go for 1 hour more, when it will be a dark purple. This color stands the sun remarkably well, perhaps owing to the fact that there is not any alum or sulphuric acid used, except that contained in the blue vitriol.

219. Blue Purple, Fast Color

219.    Blue Purple, Fast Color. 100 pounds of wool are first dipped in the blue vat to a light shade, then boiled in a solution of 15 pounds alum, and 3 pounds half-refined tartar, for 11/2 hours; the wool taken out, cooled, and let stand 24 hours. Then boil in fresh water 8 pounds powdered cochineal for a few minutes; cool the kettle to 170° Fahr.; handle the prepared wool in this for 1 hour, in which time let it boil for £ hour, when it is ready to cool, rinse, and dry. By coloring first with cochineal, as above, and finishing in the blue vat, the fast purple, or dahlia, so much admired in German broadcloths, will be produced.
