How to Fix the Above Colors Permanently.
Blue, stone, and slate-colored articles may be made to retain their color perfectly by adding sugar of lead to the water in which they are to be washed for the first time. Dissolve 1 oz. of sugar of lead in a pailful of hot water; stir carefully until it is thoroughly dissolved, and let the mixture cool. When about milk-warm, put in the articles and let them remain an hour. Hang up to dry before washing. When dry, wash as directed in bran water. The sugar of lead fixes the color permanently, so that this treatment with it will not need to be repeated. Use this preparation with caution; sugar of lead is poisonous, but no danger in this way of using it.
