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.
This can cause a glowing effect similar to looking at a brightly lit white wall behind a film of colored cellophane.
However, the pigments are not physically mixed, since the paint is left to dry before each successive glaze is applied.
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.
[2] When the technique is used for wall glazing, the entire surface is covered, often showing traces of texture (French brush, parchment, striae, rag rolling).
