Blueing (Laundry).

This article may be had in balls, powders, or in a liquid form. There are a goodly number of proprietary brands, some of which give a tint which appears somewhat greenish when placed by the side of a pure and delicate blue. The coloring principle is usually indigo, Prussian blue, or the favorite ultramarine. The most satisfactory laundry blueing is that which is really and intensely blue in tint, and which is most completely soluble in water, so that it will be well distributed and not make the clothes look streaked.
