To trim or not to trim. Is that the question?
A book conservator deals with main ethical considerations. Sometimes because of the customer desire’s, and most of the time seeking an equilibrium between preservation and functionality. To top it up, we expect the result to be pleasant as well: not too new, not too worn; most original, but not too weak…
Rare is the case when we find a salomonic solution that satisfies all the requirements.
I guess a conservator is not the type who cuts the gordian knot, but rather one who tries to unlock it no matter how painful that is! Continue reading
To trim or not to trim. Is that the question?
Conference about impregnated tracing paper conservation and premier of the video of my latest super-oversized project Continue reading
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. Continue reading
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. Continue reading
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.

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 Continue reading
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. Continue reading
Or how to remove pressure sensitive tapes, without removing them We have spoken about bibliopaths, about misuses and how to eradicate its effects… But, what happens when the artefact itself causes its own degradation? It’s not a spy movie’s myth: … Continue reading
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 Continue reading
Foxing is mould… or not?
One of the main concerns in archives and libraries is the presence of mould. Not surprisingly: it develops without fanfare, and when it is detected, an irreversible loss of information might have taken place. Before pulling your hair out, you should identify whether the symptoms actually reveal fungal activity, or not. Not an easy assessment. Continue reading
Approach to a new methodolgy to retrieve the lost flexibility to brittle papers.
Tracing papers -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. Continue reading

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. Continue reading
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. Continue reading
What are nanoparticles and chemical gels? Latest technological advances in restoration of archive material is about nanotechnology and chemical gels and so it is studied in the paper & books section of the IPCE Continue reading
