Untitled (Construction) recalls the series of glass cubes that gained Bell international recognition in the 1960s. Resembling a black-mirrored box, this recent iridescent piece produces an uncanny effect in which the interior planes seem to enclose a mysterious light. Although austere in form, Bell’s works are far from simple: he uses technology like a vacuum-coating process, to accurately control the different levels of opacity and transparency on the surface of his immaculate glass works.
