Scumble

By Scumbling is meant, the application of opaque tints very thinly, over parts that have already been painted, and that are sufficiently dry and firm, to undergo the operation; it is usually performed with a hog's hair brush, very sparingly charged with the tint to be employed; which is called a Scumble, and must be generally lighter, though nearly of the same tone of colour, as the part over which it is passed.

A Scumble is generally a tint made of some colour mixed with white; its usual effect is to render the part of the picture where it is employed, somewhat cooler, grayer, and less defined than before; hence it is of great service in connecting any tendency to muddiness or dirtiness of colouring; and also to what is called hardness, or over-distinctness of detail.
