About 100 <i>charba drawings of the Mughal period (17th18th century A.D.) were given preservative treatment. They are drawn on parchment thinner than tissue paper, in ink which can be removed by rubbing with water. Nepalese paper soaked in 10% vinyl acetate was stretched on a glass plate to provide a board on which to work. The parchment was softened with water; an aqueous solution of rectified spirit was applied to the folds which were then pressed out with a blotter. Stains were removed with running water; one much-darkened specimen was cleaned with rectified spirit. The drawing was dried first between blotting paper, and then between Nepalese paper. Mounting was done directly on Nepalese paper with starch paste made with sodium arsenite insecticide and saffrol. The edges were pasted down to the table so that the parchment could shrink uniformly as it dried. After it was completely dried it was cut away, leaving suflicient margin (1/2 inch) of paper; this margin was pasted down to the mounting board. A few of the <i>charbas had ink drawings on both sides. These were mounted on nylon with vinyl alcohol adhesive. -- AATA -- AATA
