Overview

Analysis reveals ink and pigment detachment mechanisms in palm leaf manuscripts during humid-dry cycling, highlighting conservation strategies.

Key Points

  • Ink and pigment detachment increases with humid-dry cycles, driven by a mismatch in substrate and ink expansion.
  • Chromatic analysis indicates stable chemistry; minor ΔE* increases observed in ink and substrate during the study.
  • Hygroexpansion leads to tensile-compressive stress cycling, resulting in mechanical fatigue and adhesion loss.
  • Conservation strategies focus on stabilizing humidity and using protective coatings to mitigate interfacial stress.
