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).
A midnight lockdown paper conservation dream
A lockdown is kind of stoping any activity, and that is what I have done, a stop-motion video, showing the full conservation treatment of a paper document.
Christmas angels in serious condition,on their way to full recovery!
Christmas angels currently at ICU in serious condition. Diagnosis: chronical humidity, binding dislocation, a variety of infections and rodent attack. Prognostic is optimistic because a high level team is taking good care of them. Soon they'll be bright and happy as Larry, just like in this year's Christmas greetings. Don't miss the video!
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.
Hold on and suck in, Miss Scarlett! Removing a plastic corset from a manuscript
A personal story, a historic manuscript, a crazy laminating machine and a final outcome. All these ingredients are seasoned with PFTE, TFA, HFIP, PE, DMSO, PET... cling, dong and BOOM!... An explosive -but most irresistible- cocktail. We'll discuss about synthetic polymers, sorts of laminations and encapsulation.
Posters conservation: virtual inpaint vs “virtuous” retouching
The bike riders from Sants reached my studio squeaking, rather than cycling! Tears, foxing, discolouration, brittleness, acidity... All these damages have been carefully restored in order to let the splendorous riders finish line at the Municipal Archive of Barcelona. They are almost centenarian... and yet they ride wild along the repository! I'll explain which beauty and health treatments these illustrated posters have passed through
Flattening under tension on paper and parchment conservation
Flattening under tension may be an interesting alternative to the press and very useful when a selective flattened is required: dry seals, wax seals or even parchment and ink manuscripts. Explanation based on the recently discovered oldest documents from Sants-Montjuïch archive.
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.

Silver-gelatine photographs conservation
New Elimination Procedure for Silver Mirroring. Silver mirroring is a type of deterioration that appears in most gelatin developing-out paper (DOP) historical photographs and black-and-white films. Its treatment involves so many problems that it has often been ruled out. In this article we present a new and simple elimination procedure, which is efficient and offers stable results in the long term. The study of the causes of the formation of silver mirroring sheds light on aspects that had been little explained so far: the fact that this type of deterioration always appears on the surface of the image leads us to consider a mechanism of transport of electrical charges.
Touch and “my crumpled ADLAN tracing papers”
How we restorers motivate with crumpled tracing papers, beautiful papers... This restorer is thrilled with "crumpled ADLAN tracing papers" from CoAC archive, which went through my hands some years ago, and invites you to participate in its digitization.
Gone with the wind
I don’t like much having war books, but I must admit that this one is particularly beautiful. The velvet binding seemed to me a challenging issue on the restoration, which did not have major complications besides this. I show the restoration of this book because of the headaches it has given me when solving the lost areas, the wooden work. The considerable losses on a laborious woodcarving work, and the lack of originals of many of the missing pieces fairly complicated the subject (the shields on the corners were different).
