Schlieren Chiarascuro is a fairly Representational painting. Schlieren refers to the dark lines that appear when a liquid crystal drop is place between two polarizing plates at 90 degrees to one another. The patterns formed by the dark Schlieren can be used to identify the type of liquid crystal, and to infer how the molecules are organized.
The patterns of light and dark and regions of color in a liquid crystal arise from changes in the orientation of the molecules. Smooth changes in orientation create a natural gradation from light to dark, or from one hue to another. The result is a natural chiarascuro of transmitted light.
