A Sealed Frame-Case for a Painting
A painting, egg tempera on canvas adhered to wood, had continued to exhibit overall random cracking and flaking of paint despite previous repeated attempts at consolidation. It was decided that the painting’s response to ambient relative humidity fluctuations had to be restricted. As an alternative to a traditional display case, a picture frame was modified in order to moderate the relative humidity in the immediate vicinity of the painting. It is a small sealed case incorporating silica gel. The modifications are relatively unobtrusive, and increase the depth of a painting and its frame only slightly.
