Treatment; 30 Jul 2017; Surface clean. Wash as necessary. Repair. Return remounted; Western Art on Paper

Reason: Storage
Description: A combination of chemical sponge, grated eraser, and pen-style eraser was used for surface cleaning on both recto and verso of the object, except the main image area. [1850,0211.118] A humidification chamber was used to do the humidification before washing treatment. Tap water was used to remove the textile backing strips. Warm water was used for a second washing, and a brush was used to gently brush off the adhesive residues in a water bath. Once removed from the water bath, wet cotton balls were gently rubbed around these areas to remove residues. A warm water bath was used for the third washing for about 2 minutes in order to get ride of remaining residues. [1850,0211.95] Cold tap water was used for washing first, to let the paper fibre swell up gently and then warm tap water was used to separate the lining strips. Afterwards, the object was put face-down in a water bath and a very soft brush was used to brush off the adhesive. The adhesive residue areas were very slimy, a nylon brush was used to gently brush off the adhesive residue. Local humidification was used and then the two separated pieces were pushed together using fingers in order to reduce the gap. Finally paper repairs were carried out. [1850,0211.141] Before humidification, MC (5%) was used to remove the tape where it covered the mark to test if the mark was done in sensitive media. This mark is a pencil mark and is safe for further moisture treatments. A humidification chamber was used to do humidification. Cold tap water bath was used to do the first washing, a warm water bath was used to do the second washing. A teflon spatular was used to remove the tape strips and the backing paper. Wet cotton balls were used to remove the adhesive residue. Ca(OH)2 was dropped into the cold water bath in order to rise the pH to about 8—9 to reduce the discolouration of the object. Tear repairs were carried out in three areas using Japanese paper (usumino, 11gsm) and wheat starch paste. [1850,0211.95] Losses were infilled with western wove paper, toned with water colour to match the object.
