Dear Consdist, Wishing to gather comments of a mid way treatment rinsing of a gouache.
This paper is expected to be rag / hand made paper with the graph lines screen printed onto it. That is why it absorbed discolouration over the years. Treatment: Humidfied object placed on two layers of Paraprint; the photo tray with clean water was placed fairly high above the gouache. We found that the higher the upper clean water was the better the syphon of water dripping through to the dirty trough catchment area. My 5 litre bottle was filled with discolouration from this one object (see photos) This gouache was left on the saturated Paraprint for five hours. We did lift the object from each of its margins to improve it lying as flat as possible on the Paraprint. On drying discolouration showed in places within the media. Has anyone experienced this? And has anyone placed a solution of bleach in the upper tray and it 'lightened' the work on paper'?
