Scientific Study

Since 1987, the GCI has provided scientific support to better understand the original materials Siqueiros used to paint the mural and causes of its deterioration.
Scientists at the GCI have undertaken several studies on the materials Siqueiros used to paint the mural, including pigment and binder identification and plaster characterization. Environmental monitoring was carried out to assess the effects of wind, rain, ultra violet radiation, and atmospheric pollution on the mural, and light studies were performed to show the trajectory of the sun across the mural surface at different times of day over the year (See Maekawa and Meyer, 1993).
Combined, these studies have provided conservators and architects with valuable information needed to treat the mural and construct an adequate shelter for it.
