In 1972 Olitski returned to the smaller canvases and degree of impasto that had characterised his works of the 1950s. He roughened the canvas surfaces with gel and then, using a roller or squeegee, applied paint thickened with gel and, occasionally, small beads of synthetic resin. Sometimes he brushed or sprayed greyed or monotone colours on top. In his essay for Olitski's 1978 exhibition at the Andre Emmerich Gallery, New York, Neil Marshall wrote of the artist's return to impasto:
It is Olitski's achievement to have arrived at a pictorial structure that is also a plastic structure. The peculiar pictorial logic of bas-relief is brought into a new relationship with the colour, and a kind of imagery is created that depends on the relations of colour with a plastic structure apparently independent of it. These relations constitute the structural logic of the pictures reproduced here.Olitski was very much concerned with sculpture during this period in his career. He had been given his first sculpture exhibition in 1969 by the Metropolitan Museum of Art, New York. The use of very thick impasto became a marked feature of Olitski's paintings of the 1980s and 1990s. As such, Solomon's Mirror No.2 is a work that both looks back to his Paris-inspired phase and anticipates later developments in his career.
