207. TO DYE LEMON COLOUR
Peach leaves, bark scraped from the barberry bush, or saffron, steeped in water, and set with alum, will colour a bright lemon, drop in a little gum-arabic to make the articles stiff.
208. TO DYE ROYAL PURPLE
Soak logwood chips in soft water until the strength is out, then add a teaspoonful of alum to a quart of the liquid; if this is not bright enough, add more alum, rinse and dry. When the dye is exhausted, it will colour a fine lilac.
209. TO DYE SLATE COLOUR
Tea grounds, boiled in iron vessels, set with copperas, makes a good slate colour. To produce a light slate colour, boil white maple bark in clear water, with a little alum. The bark should be boiled in brass utensils. The goods should be boiled in it, and then hung where they will drain and dry.
210. TO DYE SCARLET
Dip the cloth in a solution of alkaline or metallic salt, then in a cochineal dye, and let it remain some time, and it will come out permanently coloured. Another method: 1/2 lb. of madder, 1/2 oz. of cream tartar, and 1 oz. of marine acid to 1 lb. of cloth; put it all together, and bring the dye to a scalding heat; put in your materials, and they will be coloured in ten minutes. The dye must be only scalding hot. Rinse your goods in cold water as soon as they come from the dye.
211. TO COLOUR A BRIGHT MADDER
For 1 lb. of yard or cloth, take 3 ozs. of madder; 3 ozs. of alum; 1 oz. of cream tartar; prepare a brass kettle with two gallons of water, and bring the liquor to a steady heat, then add your alum and tartar, and bring it to a boil; put in your cloth, and boil it two hours; take it out, and rinse it in cold water; empty your kettle, and fill it with as much water as before; then add your madder; rub it in fine in the water before your cloth is in. When your dye is as warm as you can bear your hand in, then put in your cloth, and let it lie one hour, and keep a steady heat; keep it in motion constantly, then bring it to a boil fifteen minutes, then air and rinse it. If your goods are new, use 4 ozs. of madder to a lb.
