224. TO DYE SILKS BLACK
To 8 gallons of water add 4 ozs. of copperas; immerse for 1 hour and take out and rinse; boil 2 lbs. logwood chips, or 1/2 lb. of extract; 1/2 lb. of fustic; and for white silks, 1/2 lb. of nicwood; dissolve 2 lbs. of good bar-soap in a gallon of water; mix all the liquids together, and then add the soap, having just enough to cover the silk; stir briskly until a good lather is formed, then immerse the silk and handle it lively. The dye should be as warm as the hand will bear; dry quickly and without rinsing. The above is enough for 10 yards or one dress. 225. TO COLOUR YELLOW ON COTTON Wet 6 lbs. of goods thoroughly; and to the same quantity of water add 9 oz. of sugar of lead; and to the same quantity of water in another vessel, add 6 oz. of bichromate of potash; dip the goods first into the solution of sugar of lead, and next into that of the potash, and then again into the first; wring out, dry, and afterwards rinse in cold water. 226. FOR STAINING GLASS--No. 1 FLUX Minimum, or red lead, 3 parts; white sand, washed, 1 part. This mixture is melted, by which it is converted into a greenish-yellow glass. |
