Nevertheless painted approximately 90 several years back, the watercolor landscape just lately donated to the Museum of Northern Arizona continues to be vibrant with washes of purple dust, blue skies, and orange daylight glinting off the Piestewa Peaks. But raise the mat keeping this portray and you are going to place a dilemma. Organic acids in the mat have begun to discolor the edges of the paper.

Luckily, now that the painting is section of the museum collections, it is one of 2,044 performs on paper about to be rehoused by way of a $343,812 grant from the Countrywide Endowment for the Humanities.

There is a science to preserving artwork.

Opened in 2009, the selection heart is made to supply the optimum degree of security and preservation. Sustaining a steady temperature and humidity within just the developing slows the chemical reactions that trigger degradation. The NEH-funded rehousing job will increase extra concentrations of security for the portray of Piestewa Peaks and other fragile operates on paper, starting with the mats that keep them.
