Oil Painting - Scumbling

Scumbling means coating a dried painting by rubbing over it with a little straight oil paint, usually but not necessarily smearing or rubbing off the surplus with a soft cloth or the fingers. Scumbling implies the use of light or pale tints over darker ones, the use of less transparent pigments, and sometimes a rather wholesale, overall toning rather than the carefully controlled, more delicately applied glazes. [p. 113] [Mayer, Ralph. The Painter's Craft. An Introduction to Artist's Methods and Materials.

A scumble is related to a glaze in that it is a film of color laid over another paint surface so that it modifies the original color but does not completely conceal it. Unlike a glaze, the scumble is usually a light, semiopaque color placed over a darker one. Some colors (Naples yellow, for example) are particularly suitable for this technique, but any color may be combined with opaque white and used as a scumble when it is placed over a darker tone. Scumbles are usually characterized by a pearly opalescence or by a soft smoky optical effect. [p. 79] [Kay, Reed. The Painter's Guide to Studio Methods and Materials.
