stained areas under suction, drawing thesoluble deterioration components intothe underlying blotter. The application ofethanol around the treated areas helped toavoid the formation of tidelines (Photos11a-b).3. INFILLSMany objects on paper sustain physicaldamage in the form of tears and losses.Several techniques for infilling losses maybe used, including a passive method of usingthe auxiliary lining support; tracing andfilling losses with similar papers; and usingpulp infills to approximate the color andappearance of the original support (Photos12a-c).This manuscript Map of the South Westernextremity of Manitoulin Island, produced ona thin wove paper support, was discoloredwith large losses along the left and rightedges (Photos 13a,b). The media weretested prior to treatment and found to bestable in water and ethanol. The conservatorchose to infill the losses using paper pulpmatched to the color and weight of thesupport. The method is quick and precise,provided that the artifact can withstandwetting out.STAIN/DISCOLORATION REDUCTIONWashingBleachingPoulticesImmersion in alkaline water bathLocal treatment using suction tableor suction platenCapillary washingBlotter washingImmersion in oxidative or reductionbleachesLocal bleaching using suction tableor suction platenLight bleach: sunlight or artificiallightLocal treatment using laponite,gellan gum, etc.Diagram 2 Stain Reduction TreatmentsLight bleaching apparatusPhoto 10a Detail, after treatmentPhoto 10b Detail, before treatmentPhotos 10a-b Map of the Saint Lawrence River, 1815-1820, 25.0 x 108.2 cm, Library and Archives Canada, MIKAN 4517130.Before treatment.61
