Thanks for sharing the basic treatment process here. - I suppose that the sodium citrate solution varies according to the specific piece being treated, but what would be a typical concentration used? - It would be very informative to have at least a brief description of how the artwork is handled after the immersion bath and removal of the cleaning solution, to ensure proper drying, minimize warping and waves, etc.
thank you. I am in the process of restoring my grandfathers portraits. He was Ernest Walter Histed, Sr. His works are from late 1800'2 to 1920's. Foxing on the paper. he used platinum glass negatives
This is a great video. And I am very thankful for the effort that the conservator took in showing how to clean that beautiful engraving. One question, however, remains in my view. What would be the best way for drying the sheet? It should probably dry slowly. On what kind of material should it lay for drying, may be linnen? Should it be pressed in that process?
I'd like to know that too. Laying on a horizontal piece of stretched (framed) linen canvas is the way to go, but I've only seen it when the poster is glued to it so I don't know how easily peeled off the linen might be after drying. As for pressing, careful draping and gravity will do most of the work, but I'd probably put an acetate sheet over it and use a roller to make sure any kinks are ironed out. I'm told a standard movie poster will dry in 24-48 hours. You can see in the video that the bottom is wavy but like you say it feels like that's not the "walk away" stage of the process.
