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).
Profession: book and paper conservator
What does a paper conservator do? Whom does she work for? What skills and knowledge does she ought to have? Preservation and conservation, a field linked to science, history and arts and crafts. A video explains what differenciates us from forgers and shows -among other- how we produce a hand-made suction table to restore paper artifacts, with loads of creativity, a feature most necessary to become book and paper conservator.
A midnight 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!
Retouching, a taboo in paper conservation?
Retouching is among the most sensitive within ethics in conservation since it means to establish the aspect a restored object is expected to have. My opinion is that the looks of an historical object is often as important as its physical-chemical condition, and not intervening provides poor results that might mislead its readability more than a proper intervention. The more we intend to make it as neutral as possible, the least arbitrary, we need to admit that retocuhing requires good taste.
Silver Mirroring Removal in Photographs (Video)
At last a deffinitive method, safe and efficient for silver mirroring removal in historical photographs. This new treatment will change the way the issue of silver mirroring removal has been addressed in photographic collections. See it in this video and value the results.
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.
Untangling tensions, for an improved 2019
We wish you merry Chrsitmas and a better (and restored) 2019, untangling knots and tensions, at least those from parchment manuscripts.
Silver Mirroring: Its Importance, Formation Process, and a New Elimination Procedure
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.
Unlocking St. Anthony’s locked manuscript
"Tony, Tony, come around, something’s lost and can’t be found!" Some manuscripts require more than just manual skills to succeed in their conservation, and so we prayed to Saint Anthony to help us unlocking the bookbinding, whose key had been lost forever. Certainly not many renaissance bookbindings have an iron safety lock in their covers and thus this extra holly help was deemed quite necessary. The prayer didn't provide any key, but at least a satisfactory conservation solution was achieved!
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.
Sōkō conservation for oversized sketches by Sorolla
Sorolla sketches represent the spontaneity, the genius and the creative stage for its own right. Their conservation shares with them this essentiality, the minimal intervention character. The restoration has adopted japanese tools and techniques, a paper conservation at the most eastern style. Or not that utmost, since the Karibari was replaced by a wooden board. Eastern or western, the restoration of the gouache sketches has been truly remarkable, and you'll have to read it to know why.
Endbands, headbands and ties
The headband to a book is like the tie to a suit: they both give their owner the chance to stand out. It is like the icing on the cake of the binding, and gathers the bookbinder's proficiency and taste. We'll discuss their aspect like in a Vanity Fair, and go beyond: What are they meant for? and why stuck-on headbands are less cared by conservators than sewn ones? Should we replace them or conserve them? The untrained eyes will look at them with more interest now, because -just like ties- there are headbands for all tastes!
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. We'll discuss about synthetic polymers, sorts of laminations and encapsulation. All these ingredients are seasoned with PFTE, TFA, HFIP, PE, DMSO, PET... cling, dong and BOOM!... An explosive -but most irresistible- cocktail.

Conservation of ‘The Disasters of War’, by Goya
There are all sorts of projects, and when Mr. Goya knocks at the door, the red carpet is ready to receive him at the studio: Please, come in! The Disasters of War by Francisco Goya arrived at the studio in a fairly intact condition, with its 80 etchings, corresponding to the very first edition (in later editions two more etchings were added, making a total of 82). This first one was edited in 1863, more than forty years after
“Customized” conservation with Richard Wolbers
Fellows of joys and sorrows, conservators, here is why I am so excited with the "Cleaning workshop: Paper bathing/stain removal", given by Wolbers: The idea is to make every conservation treatment a kind of custom-made dress for each particular object with a minimal initial investment. He speaks about solvents, gels, surfactants, conductivity and pH. Nor in my wildest dreams had I imagined such a close, easy and useful chemistry. Thanks a lot Richard, we owe it to you.
