  • 1.  glassine stuck to surface

    Posted 21 days ago

    Hello, 

    I'm looking for some advice on removing a piece of glassine that is stuck to the surface of a oil on paper. It was stored improperly and overtime the pressure of the other WoP stacked above adhered the glassine to the surface. We did a small test to see how easily it comes up on a corner hidden behind the mat and there's some resistance, but it comes up without any visible damage. From what I've read, the safest option seems be light humidification with distilled water? 

    Thanks!

    Ellen

    Hi Ellen,

    As the acting C2C Care community monitor, I'd like to thank you for posting this question to the community. Yes, indirect humidification, which can be applied locally or overall, can be used to ease the removal of the adhered glassine. I've attached some resources that provide descriptive information on humidification treatments, indirect water application techniques, and importantly, factors to consider before undertaking either treatment.

    AIC Wiki – BPG Hinge, Tape, and Adhesive Removal – Sections 1 Factors to Consider and  6.4, Poultices https://www.conservation-wiki.com/wiki/BPG_Hinge,_Tape,_and_Adhesive_Removal#Poultices

    As always, community members are welcome to offer additional guidance and resources.

    If both the media and paper support are stable, paper poulticing with blotter could be the most straightforward option. Be sure to test the method in a non-conspicuous area before scaling up, starting with minimal amounts of moisture/time to avoid creation of tidelines. Conservation staff at one of your local institutions could also offer guidance if needed.
