Glaze (painting technique)

Glazes can change the chroma, value, hue and texture of a surface. Drying time will depend on the amount and type of paint medium used in the glaze. The medium, base, or vehicle is the mixture to which the dry pigment is added. Different media can increase or decrease the rate at which oil paints dry.

Often, because a paint is too opaque, painters will add special media or a lot of medium to the paint to make them more transparent for the purposes of glazing. While these media are usually liquids there are solid and semi-solid media used in the making of paints as well. For example, many classical oil painters have also been known to use ground glass and semi-solid resins to increase the translucency of their paint.

Oil painting

In oil painting, the simplest form of a glaze is a thin, oily, transparent layer of paint spread over the top of an opaque passage that has been given some time to dry. Light travels through the glaze and is reflected back off of the opaque layer below. This can cause a glowing effect similar to looking at a brightly lit white wall behind a film of colored cellophane. The thin oily layers of a glaze can facilitate the rendering of details that would be more difficult with opaque paints—e.g. the complexities of skin tones.

When multiple layers of glazes are used, the colors in all visible layers can appear combined. However, the pigments are not physically mixed, since the paint is left to dry before each successive glaze is applied. The artist may apply several layers of paint with increasing amounts of oil added to each successive layer. This process of applying the fat layers (more oil in the painter’s medium) over the lean layers (less oil) can minimize cracking; this is the "fat over lean" principle.

Many painters juxtapose glazes and opaque, thick or textured types of paint application (that appear to push forward) as a means to increase surface variety, which some painters feel increases a painting's drama, brightness and depth.[1]

Wall glazing

When the technique is used for wall glazing, the entire surface is covered, often showing traces of texture (French brush, parchment, striae, rag rolling). Either oil-based or water-based materials are used for glazing walls, depending upon the desired effect. Kerosene or linseed oil may be used to extend the "open" or working time of oil-based glazes. Water-based glazes are sometimes thinned with glycerin or another wetting agent to extend the working time. In general, water glazes are best suited to rougher textures where overlaps of color are acceptable.

Glaze is also used in cabinet, furniture, and faux finishing.

Scumble is a technique similar to glazing, except that the coating is opaque, and is just painted on very thinly to allow bits of the paint below to shine through. Scumbling works by a similar principle as the pointillists use—mixing colors optically. While most painters glaze with dark colors, scumbling is more popularly used for lighter colors; especially atmospheric effects when rendering fog or clouds.
