Large Di-Chroic 'Ice Cube' by Harold Lustig in Action

Di-Chroic is a finish perfected by NASA for use in the space shuttles. The word comes from the Greek-"Di" meaning two and "Chroic" meaning color. The layering of the di-chroic finish must be done in a vacuum chamber where an electron beam deposits many microscoptic layers of metallic oxides, such as magnesium and titanium, on the optically pure glass. The metallic coating absorbs different colors of light at different angles making the glass multi-hued. The cubes-on-base are coated on the three concave undersides. This allows the color to "Bounce" around inside the cube. The other pieces in the line are coated on the bottom and then covered with felt to protect the finish.
This sculpture consists of 8 - 80mm cubes fused together as one on a mirrored base.
