Technical Expertise and Search for Authenticity

Annette Douay, restorer of paintings for more than 30 years, has set her eye on several thousand paintings. Holder of the diploma "Expert: Law and Authenticity of Works of Art" from Panthéon-Sorbonne University Paris II, she puts her experience, in partnership with the Pierre and Marie Curie university laboratory, Paris 4, at the service of institutions and individuals alike.

She's an expert concerning the materials that constitute paintings, and, according to the findings provided by the hyperspectral imaging by LAMS, she comprimises technical and scientific files and may issue, when necessary, certificates of authenticity.

There are multiple roles for an expert: they can be an adviser and can also respond to specific assignments such as:
The verification of the attributed artist
• The work's state of conservation
• Damage estimation
• Estimation sheet for conservation and restoration
• Ensuring the correct insurance value
• Drafting the Condition Report before and/or after moving works, etc.



Analysis of the Work:
After verifying the authorship of the work, an approximation will be made first based on professional iconography databases.
Then various means of observation (direct white light, tangential, transmitted light, digital microscopy, fluorescence under ultraviolet, infrared, X-rays) and identification of the materials used in the work (textile fibres, pigments, mediums, varnishes etc.) by Hyperspectral imaging, will make it possible to establish the "technical identity card" of the works analysed.

Authentication of Works by Materials:
The results obtained can then be compared with the artist's iconography in order to verify and establish, if necessary, the authenticity of the work.

Thanks to its partnership with the Pierre and Marie Curie Laboratory, Paris 4, the Atelier du Temps Passé is the first French restoration workshop to offer academic scientific quality on the private market.

Example 1: You have inherited a painting attributed to X painter.
Did they actually paint it? What' its condition? What might be its current value?

Example 2: The piece you plan to buy is presented to you in excellent condition..."Condition report"?
Is this painting really in excellent condition? And is it worth the price?

Example 3: You have a painting signed by "X" Painter...
Is the signature authentic?

Example 4: You are told that the painting you would like to acquire is from the 18th century (or earlier)...
Is that true? Is it from that time? Or more recent?

Example 5: You plan to transfer your assets and you ask about their condition...
Are your assets in good condition? Do the paintings require restoration work? What would be the priorities? What would it cost? Are they kept in the best conditions?

Example 6: You want to check your insurance coverage....
Is your piece adequately insured?

Example 7: You have suffered water damage, fire, vandalism...
What is the damage to your piece(s)? Is a restoration possible? Are the benefits offered by your insurance company properly valued?

Example 8: The piece that was sold to you is not what you expected...
Was the restoration work that was done carried out in accordance with the criteria of professional deontology? Has it been devalued?

All these cases mentioned, and many others, to which the Atelier du Temps Passé will undoubtedly be able to provide an answer...
