2742. Gum Arabic Starch
Procure two ounces of fine white gum arabic, and pound it to powder. Next put it into a pitcher, and pour on it a pint or more of boiling water, according to the degree of strength you desire, and then, having covered it, let it set all night. In the morning, pour it carefully from the dregs into a clean bottle, cork it, and keep it for use. A tablespoonful of gum water stirred into a pint of starch that has been made in the usual manner will give to lawns (either white or printed) a look of newness to which nothing else can restore them after washing. It is also good (much diluted) for the white muslin and bobbinet.
