A strategy is reported to optimize lighting to reduce photochemical degradation of works of art and archival documents. The strategy revolves around improving luminous efficiency of the spectral profile to exclude light which doesn't contribute to br

Summary When conservators of art on paper in the USA find it necessary to carry out a bleaching procedure the method most frequently chosen is aqueous light bleaching. Experiments and practical experience with this technique have shown that when appl

The immediate and long-term effects of aqueously light bleaching both unsized and gelatin-sized cotton cellulose papers in either calcium hydroxide, Ca(OH)2, or magnesium bicarbonate, Mg(HCO3)2, solutions were investigated. After samples were treated
