Abstract
ABSTRACT This research explores the viability of using diatomaceous earth stone mats, a commercially manufactured, rigid, absorbent board marketed for home use (aka DE stones) as a sustainable tool in paper conservation. Analytical studies, including X-ray fluorescence, Fourier-transform infrared spectroscopy, gravimetry, colorimetry, accelerated aging, pH, solvent reactivity, and absorbency testing, were conducted at the National Archives and Records Administration on the DE stones and on Whatman® filter paper samples. The experiments with samples dried in direct contact with DE stones showed no undesirable transfer to the filter paper. Gravimetric analysis showed the drying rate of samples placed between DE stones was much more rapid than for samples placed between blotter or wool felt. Colorimetry before and after accelerated aging of samples dried in direct contact with DE stones showed no undesirable aging patterns. Successful case studies illustrate high potential for the use of DE stones in paper conservation treatments.
