Ultrasonic misting in the treatment of works of art on paper

João Paulo Dias


A solution of calcium hydroxide and sodium borohydride was applied using an ultrasonic misting device to a graphite drawing from the artist Guilherme Camarinha. This process allowed the drawing to be washed, reduce its foxing stains and planar distortions without interfering with a fountain pen inscription written by the author in the bottom righthand corner. As there is not much literature regarding this procedure, some practical questions related to the use of ultrasonic dispersions in the treatment of paper are discussed herein.
