Doris's diamonds

Covering the interior walls of the White Cube gallery with plasterboard, Colombian artist Doris Salcedo has, in turn, embedded the plasterboard with diamond-shaped steel fencing. The fencing extends to cover partially the entrance to the gallery. Other than this, the room is empty.

Salcedo is known for her austere installations that seem to hint at loss or human suffering. But, like Polish artist Miroslaw Balka with whom Salcedo has exhibited, her works are often enigmatic and elusive; interpretations are offered that have little to do with the formal qualities of the piece. Past installations, for instance, have included furniture filled with concrete.

When, however, the materials act as a form of visual shorthand, there could be a danger they turn into uncomfortable clichès. In one exhibition, for example, shoes were stuffed into niches cut into gallery walls. These shoes, we learned, were taken from the victims of Colombia's civil war and made an obviously chilling connection to the piles of shoes belonging to victims of the Holocaust.

In this current work, thoughts turn to incarceration. Or perhaps to those who are unwanted being kept out, such as refugees. Either way, the title of the piece hints at some uncomfortable ambivalence.
