Regina Valluzzi

Arlington, United States

Artist's Description

Oil on primed Linen, 12 in by 12 in; March 2011

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.

One of a series of paintings addressing scientific imagery as metaphorical visual information. Through a change of context, these paintings (and drawings) explore an communicate the experiential aspects of investigation and discovery. By providing an alternative abstracted depiction of worlds an ideas that cannot be directly seen, a connection is built to the everyday world of objects.
