Works from this series were painted with one kind of black oil paint, Winsor&Newton No. 25, which is called Lamp Black. Central to these monochromatic pictures is the shaping of the painting’s surface so that, when struck by various kinds of light, falling from different angles, of various temperatures and intensities, the work creates the illusion of being three-dimensional and multicolored. The pictures from Lamp Black series have no “right side up” and can be presented any which way, and thus their changing positions and illumination can generate an endless number of compositions and colors. The inspiration for the first pictures in this large series was the geometrical shapes of lumps of coal. The following works, which eschewed mimetic associations, focused on breaking through the flatness of the picture, ultimately leading Bujnowski to paint canvases on irregular, multi-angle stretcher bars, which were finally spatially deformed as well.
