A Safe and Efficient Method for Silver Mirroring Removal in Photographic Conservation

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. Continue reading

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. Continue reading

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. Continue reading

“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. Continue reading

Chemists and conservators: a love/hate relationship

A cathartic experience: There’s nothing more exciting for a conservator such as participating in a chemistry course. We go there with a certain respect (or maybe fear) and the will to be acquainted to a new miraculous reactant that will change our life.
The poor conservator will poorly be able to discuss one to one with a chemist, either about the reactions that happen during the restoration treatments or along the inherent ageing of the artefact; and yet we must call the chemist into question and keep this dialogue alive. But thanks to Richard Wolbers I made peace with chemistry and their scientists. Continue reading

Nanotechnology & chemical gels applied to paper conservation

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
