Read the passage below:
Long before conservator Kenji Sato presented the fully restored sixteenth-century Japanese screen printing to the museum board in 2018, his restoration team had undertaken a meticulous stabilization project. The delicate artifact had been discovered in an abandoned temple storehouse in 2005, although municipal records indicated that monks had relocated the screen there following a catastrophic river flood in 1972. Before any chemical cleaning could commence in 2012, Sato spent three years cataloging the pigment degradation under ultraviolet illumination. It was only after completing this detailed pigment analysis that the team applied an organic binding gel in 2015 to stabilize the flaking gold leaf, a procedure that preceded the screen's final re-housing in an airtight glass casing by exactly two years.
