This object relates to the painting Lost Mine, displayed nearby. Lanyon often used materials found in his studio to make three-dimensional constructions that helped him develop the space of his pictures. Pieces of glass stuck together with black paint and glue were especially effective, as their transparency suited the ambiguous spatial organisation of the paintings. Here, the vertical axis of the construction, coated with black, refers to the flooded mine shaft. The red pigment, also seen in the final painting, may signal danger and the loss of life.
