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

I have mold! (…or is it foxing?)

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.

Flattening under tension on paper and parchment conservation

Wrinkles and folds are a usual damage in documents made of paper, cloth or parchment. The common way to restablish these supports to its original condition is by pressure: under weights or in a press. When the paper has a relief which must be preserved, it is then not possible to use pressure, as it would smash this relief. Flattening under tension may be an interesting alternative on certain occasions or when a selective flattened is needed. It takes advantage of the natural shrinkage of the paper when going from wet to dry, so that the tension is given by the same paper.

New conservation methodolgy to retrieve lost flexibility to brittle tracing papers

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.

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.

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).
