This post was written by Amy Sullivan, Preservation Officer for George Mason University Libraries. You can follow Amy’s adventures in preservation on Instagram @gmupreservation. SCRC sent items from Randolph H. Lytton Historical Virginia collection to be de-framed by Amy and her student, and she noted this document made of parchment that was covered in *GASP* scotch tape.
Pressure sensitive tape is the bane of archival collections. It’s never good for preservation, but in this particular case it’s bad for a new reason: it’s on parchment. (A quick primer: parchment is hide that has been prepared by paring and stretching under tension as it dries.) Unlike paper with similar problems, you can’t heat the adhesive (in this case, tape) to make it pliable – heat can shrink and even split the parchment – or use anything wet, like a solvent (as moisture introduces the possibility of warping and stretching). this means it’s time for some good old fashioned mechanical reversal. Yep, that’s right, time and patience and a microspatula are all you need. (Side note 1: always stop when the friction caused by stabilizing your spatula hand with some fingers against your work surface start to bleed. Preferably before it ends up on the item under treatment. Side note 2: transparent tape means you’ll be working almost 100% by feel to know where the tape is and when you’ve removed it all.) Below are some pictures of this process. Enjoy!
