Conference about impregnated tracing paper conservation and premier of the video of my latest super-oversized project
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!
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 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.
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.
