Premiere of the video of the conservation treatment of a map
Premiere of the video showing the full conservation treatment of an oversized hand-coloured map, varnished and lined on a canvas. Do not miss it! Next Thursday 27 at 4pm CEST (UTC+2).
Save the date: Tuesday 21st at 11h
Conference about impregnated tracing paper conservation and premier of the video of my latest super-oversized project
Housing as a (quite desperate) conservation resource
New artwork arrives at the studio to be ready for an exhibition: pressure, limited time, bleeding inks... Could it not be some other easier and more showing off artefacts? Here's what I do when I don't seem to find much to do: Tape removal, and failing to flatten under tension with magnets... Mounting the artwork on a housing that secured an even tension on the artwork during the exhibition, was the last resource.
Gels, microemulsions and nano-systems applied to pressure sensitive tape removal: latest updates
Tape removal, chemical and physical gels, microemulsions and much more. Review and abstract of the conference "Nanosystems. Application to tape removal on cellulosic supports,", which took place in Madrid (Spain), on June 6 to 8th, 2018; within the context of NanoRestArt, the european Research and Developement project.
Bibliopaths: The case of the lacquer binding
Are we supposed to fear bibliopaths? Or maybe we should give them an award? Who are they? Atention! Because they can be among us, or we might even be one of them?! I invite you to read the Case of the Lacquer Binding to know more about them
New conservation methodolgy to retrieve lost flexibility to brittle tracing paper
Approach to a new methodolgy to retrieve the lost flexibility to brittle paper. Tracing paper -so usual among technical drawings- have in common their transparency, but there are significant differences in the process to make them. The properties and behavior will be very different then. Impregnated papers, for an instance, were applied oils or varnishes to provide them translucency. Explanation restoration of several drawings in which the varnish was removed to replace it later.
Damned “sellotapes”!
Which damages cause sellotapes? Can we release documentary heritage from these fatty strips? Explanation for the degradation mechanisms of this historic "remedial" tapes that we can find in documents of all kinds, and restoration possibilities in each case.
Conservation of school poster from spanish civil war period
This map represents the typical scholar posters: with its wooden slats to roll and hang, lined on the back. It was very common to varnish them with shellac to waterproof and protect them from abrasion. This one was made of two pieces of printed paper, sticked together along the central horizontal stripe. It is from 1936, spanish civil war was barely breaking. Removing the old varnish has allowed to repare other minor damages: tears, gaps and wrinkles. But most important is that the new varnish is not oxidizing nor yellowing. As it is very flexible it will not crack in the future.
