Concreto 4.0/02 presents a quiet collision between the elemental and the luminous. Cast in raw concrete and embedded with fragments of coloured glass, this compact 2013 work distills David Batchelor's longstanding fascination with the chromatic life hiding within industrial and everyday materials. The glass catches and refracts available light, introducing bursts of saturated colour into the grey austerity of the concrete ground, creating a surface that shifts in character depending on viewing conditions and time of day. Batchelor, a Scottish-born artist long based in London, has built a celebrated practice around what he terms "chromophobia," the deep suspicion of colour that he identifies running through Western culture. Works like this one offer a pointed counter-argument. By anchoring vivid colour within one of the most utilitarian substances in the built environment, Batchelor refuses any hierarchy between the decorative and the structural, the beautiful and the functional. The concrete does not suppress the glass; it frames it, lending the colour a weight and permanence it would not possess on its own. At just 31 by 41 by 6.5 centimetres, the work is intimate in scale, inviting close attention rather than demanding it from a distance. Signed by the artist and offered through Galeria Leme, Concreto 4.0/02 would sit naturally in any collection engaged with materiality, abstraction, or the ongoing conversation between Arte Concreto traditions and contemporary British practice. It is a resolved and quietly generous object.
