Art + Work | Removing stains from a Japanese print

[@brylorbs69]

A very interesting demonstration but did it work? Was the foxing removed? A "before and after" would be nice to see.

Hi! Conservator Madison Brockman shared this update: "Foxing is often difficult or impossible to fully 'remove,' but this treatment was very successful in reducing its appearance. After bathing, the print dried for a whole month in a weighted pressing stack of cotton blotters, so the filmmaker could not include its appearance after treatment on the day of filming."

@@lacma Thanks for this explanation. Yes, a one month time-lapse would be challenging! :-) Keep these wonderful videos coming. We love them!

Thanks so much for the instructional video. I’m curious if the ink on that particular print was water based? Where do considerations of ink material and conservation material enter into the restoration process?

I need to remove foxing from 3 Japanese Prints, do you publish information about this; details of the ratios of sodium citrate and calcium accetate to the gellan gum solution etc?

Thanks for the video! I wonder whether the water dissolves the ink??

What is the cleaning solution?

[@zvonimirtosic6171]

Paper foxing .. is it due to the impurities in water during the paper production, or during the ink laying process? Too much iron (Fe) in water ..?

[@JimOConnell]

I think it is from impurities in the material used to for 'sizing' the paper. Not size as in length and width, but a glue-like material used to give the paper a better surface so that inks don't blur and bleed.

I find these videos on restoration most interesting, I'm glad those of you at LACMA share them. You've offered many details however I'm curious about the brush, whether it's stiff or somewhat soft, what are the bristles themselves? Thank you. Robert @ Innate.Style

Hello! Conservator Madison Brockman shared this response to your questions: "We use a variety of brushes in treatments like this. For dry surface cleaning, we often use a very soft 'hake' brush made of goat hair. The stiffer Japanese water brush used to smooth out the object on the gel is called a 'mizubake' and is made of densely packed deer hair."

@@lacma Thank you so much for this answer and the details. In addition to finding the art pieces interesting I enjoy learning about the tools used in the creation or restoration. The actual hair used in these brushes in particularly interesting. Thank you again.
