Royal Blue (Into a vessel of cold water)

Into a vessel of cold water add 2 pints nitrate of iron; then take 1 pint water and 1/2 pint of hydrochloric acid, and add to it 3 ounces crystals of tin; when water as hot as the hand can bear, dissolve a little white soap-enough to raise a lather; then add 1 gill archil liquor, and work the goods for 15 minutes, wring out and dry. To obtain a redder tint, boil 1 ounce cudbear, and use instead of the archil liquor. A still redder tint is attainable by leaving out the soap altogether. 262. Violet, Lilac, Wine Color, &c!

Work the goods for 20 minutes in plumb liquor (see No. 111) in a copper pan or stoneware vessel; wash out repeatedly until the goods cease to taste of the liquor, then dry.

To obtain a rich blue shade, add to the plumb liquor 1 fluid ounce either sulphate or extract of indigo. For a red shade, first dye a lavender by cudbear without soap. (See No. 261.)
