Icon Book and Paper Group: Lecture about Impregnated Tracing Paper Conservation

CASTELLANOCATALÀ

  • Organization: Icon Book and Paper Group (London). Webinar series #ConservationTogetherAtHome
  • Lecture: Conservation of Impregnated Tracing Paper.
    This lecture was held first in the Hague (Netherlands), in the Symposium Technical Drawings and Reproductions, organized by Restauratoren Nederland (October 2014). The study cases discussed then belong to the collection of CoAC (Architects Association of Catalonia). Now the lecture is revisited, updated and with a few study cases more, from Art Center Grau-Garriga (Sant Cugat del Vallès, Barcelona) and Municipal Archive of Renteria (Basque Country, Spain).
  • Speaker: Rita Udina.
  • Fee: Free entrance.
  • Submit here:  Registration to the Zoom Webinar (registration closed).
  • Date: June 9th, 2020, at 4:00 pm BST (London time). The lecture will be recorded and uploaded at the Icon Book & Paper YouTube Channel (link available here in short).
  • Pdf notes of the powerpoint presentation (click to download).
  • Abstract:
    Impregnated, prepared, vellum or oiled papers are different names for this type of tracing paper that was produced by coating the paper with a varnish in order to make it translucent.
    Most commonly used oils have inherent oxidizing features, making the paper brittle and acidic after time. Fragility may be such that dissuade against any manipulation, since a regular handling might involve tears. The varnish also prevents cellulose from moisturising normally and its conservation is therefore quite complex. A replacement of the varnish intends to stop oxidation and enable wet treatments in order to improve the paper condition as well as maintain its transparency.

Here’s the lecture!
(I must correct myself in the misuse of the word “rows”, which meant to say “columns”, at the very last slide, from the minute 54′ on… my appologies for the confusion!)

With tomorrow's talk, we have reached a mindblowing #ConservationTogetherAtHome webinar number 30! Once again, we want to thank all the speakers that gave their time and decided to share their knowledge and findings with the rest of the conservation community 👏🏻👏🏻👏🏻 We are happy and proud to have been able to put this together. And let me take this opportunity also to thank all the fellow committee members of the Icon Book & Paper Group who have done SO much work to organise talks, host them and all the rest of the work that happens behind the scenes! Tomorrow we'll hear from Rita Udina @ritaudina_conservation about the 'Conservation of oiled or impregnated tracing paper'. Oiled (or impregnated) paper is a kind of tracing paper that was produced by soaking the paper on a varnish in order to make it translucent.
Most commonly used oils have inherent oxidizing features, making the paper brittle and acidic after time. Fragility may be such that dissuade against any manipulation, since a regular handling might involve tears. The varnish also prevents cellulose from moisturising normally and its conservation is therefore quite complex. A replacement of the varnish intends to stop oxidation and enable wet treatments in order to improve the paper condition as well as maintain its transparency.
Rita Udina is paper and book conservator based in Barcelona (Spain) at her private conservation lab where she works for Archives, Museums, Libraries and private collectors since 1999.
She organizes international conservation courses at her studio as well as in other countries and with other institutions: Restauratoren Nederland, Institut National du Patrimoine, Paris; Universidad de Granada…
She enjoys sharing conservation in conferences, papers, and on social media, particularly with her blog (https://ritaudina.com) which has followers from all over the world. ➡️Follow the link in bio to register for the talk, June 9 at 4pm BST, and as always, there's the #ConservationTogetherAtHome hastag to use if you fancy 🙂 #conservation#paperconservation#tracingpapers#oiledpapers#transparentpapers#impregnatedpapers#preservation#fragile
