Before treatment a detailed shot of a map that had been damaged by water resulting in mould, which is visible in the black, green and white stains.
Before treatment, the map was in a fragile condition, the paper was acidic and weak with several small tears & losses.
The reverse showing acidic discolouration and a repair patch to the bottom centre edge
Viewed in raking light the repair patch on the reverse can be clearly seen, as can the losses.
A close up of some of the worm hole damage.
During treatment the map is cleaned removing soluble acidity. Old repair patches are removed as is acidic discolouration.
A thin sheet of handmade Japanese paper is pasted & applied to the reverse of the map to strengthen & support it.
After applying the lining the map is placed face up. Tears and folds are checked & repositioned.
. A corner that had been pulled away from the work due to inaderquate mouting was reunited. .
The losses were inpainted with watercolour, a different medium to the original printing ink used thus enabling easy identification of the retouching.
The Japanese lining paper was trimmed away carefully following the contours of the uneven edges.
The map after its preservation. The disfiguring losses have been repaired restoring the maps intergrity.

Before treatment the map had been backed on a stiff poor qualtiy kraft paper and tightly rolled.
It was difficult to view the map while adhered to backing, this photo was taken after humidifying the work.
After treatment, the acidic backing and adhesive was removed. Then the map was cleaned and flattened, mounted and framed using 99% ultra violet filtering glass.
