Dichroic Crystal  Glass Cube by artist Harold Lustig (1928-2018).  Lustig deposited thin layers of metallic oxides on the glass; each absorbing different spectral lights. As different colors are absorbed, other colors are reflected, and so the color bursting from the glass changes as light hits the different oxides. Because of this, Lustig’s dichroic glass captures different colors as the sun catches it at different angles.  This cube measures approx 2" x 2".  With the base, the height is approx 3".  There is a very small chip on the base-see pics 9-10.  A stunning piece!
