During the 1990s, Anish Kappor made sculptures that appear to be pure pigment. The first room of the retrospective at the Royal Academy was filled with pigment sculptures, plus the pregnant wall.
Later on in the exhibition, a series of rooms dedicated to extrusions. This (left page) is two views of a very large extruded (really constructed) form. The (right page) other is an immense rusted steel form that is closed at one end, open at the other. The relationship to the domed gallery delighted me. I did not attempt to draw the cannon shooting red wax nor the train-like machine that moved a block of wax tbrough five galleries.
