OUR DEVICE PORTFOLIO
MULTILAYER a method for image stratigrafy of paintings, INTRAVEDO a ultra high resolution IR scanner AND positioning system ... unique technologies that will answer many of your questions about what is on the painting and even more what is hidden under the superficial paint layer.. The instruments employed by Art-Test are the result of a thorough and complex study carried out by experts with wide experience in this field, with the objective of optimizing both performance and portability. Most of the appliances that Art-Test employs have been designed and realized in-house, thanks to the know-how and expertise acquired by its professionals and by our partner companies, specialized in scientific instruments, as well as to the cooperation with research institutes. Some of our devices are for sale. If you are interested ask us for a quotation!

The book documents the restoration done on the precious wooden crucifix , unattributed but dated to 1495-1500, close to Benedetto da Maiano school. The publication goes through the work of restorer Lisa Venerosi Pesciolini and the latest methods of diagnostic analysis applied by Art-Test. Now, after this accurate intervention, the crucifix will be returned to a new place of honor back inside Fuligno’s Cenacolo site, in Florence, with an official presentation on May 19th, at 12.00. << click on the image for more info
6 dec 2011 The miraculous "Madonna delle Acque" is back in Impruneta after some restoration. During the conservation work some new interesting data has emerged thanks to RX and IR reflectography. The outcomes were presented at Circolo Cattolico San Giuseppe in Impruneta. << click on the image for more info
