Reflectance Spectroscopy for Paper Conservation. National Archives, The Netherlands

2017-11-01T07:03:00+00:00

Reflectance Spectroscopy is a powerful method for pigments identification even for works of art on paper. We just delivered on Oct 24th a full day Training and a Gorgias Spectrometer system to the Paper Conservation Department of the National Archives of the Netherlands in The Hague. Read and learn more about Reflectance Spectroscopy and our [...]

Technical examination for Statues – suggestions and a case study – St. Elijah in Comiso, Sicily

2017-06-28T12:43:22+00:00

We just performed a diagnostics service for a statue of St. Elijah, in Comiso, Sicily. This is a good opportunity for our art conservation community to review technical photography, spectroscopy, and other tools for the documentation of antique statues,  a preparatory examination for the conservation treatment which is undertaken by the Conservation Studio Tiziana Cilia [...]

Mapping covered paints with Transmittance spectroscopy and transmitted multispectral imaging

2016-12-19T04:18:57+00:00

How to identify and map covered paints on translucent support, such as canvases? We just published:  A. Cosentino “Transmittance spectroscopy and transmitted multispectral imaging to map covered paints” Conservar Património 24, 37-45, 2016. doi:10.14568/cp2015021 Transmitted spectroscopy and transmitted multispectral imaging in the 400-900 nm range have been applied for the mapping and tentatively [...]

Reflectance spectroscopy of new pigments

2016-10-17T16:32:22+00:00

We just updated our database of Reflectance spectra of pigments with the new 4 pigments added in Pigments Checker v.3. DOWNLOAD Reflectance Database: A. Cosentino “FORS spec­tral data­base of his­tor­i­cal pig­ments in dif­fer­ent binders” e-conservation Jour­nal 2, 57–68, 2014. We added Reflectance spectra of bitumen, chrome yellow, cobalt blue and cobalt chromite blue. Pigments Checker is a [...]

Miniaturized Spectrometers for Art Examination

2016-10-17T16:33:04+00:00

Read this great article on Photonics Spectra! Spectroscopy: Going Small to Get the Whole Picture Now miniaturized spectrometers are also used in Art Conservation. CHSOS illustrates in this paper  the possibilities that miniaturization will bring in the near future of on-site art examination. CHSOS has been disseminating the use of innovative, affordable and sustainable technologies for art [...]

How to Identify Pigments with Reflectance Spectroscopy

2016-10-17T16:33:05+00:00

CHSOS just added a miniaturized spectrometer to its instrumentation. This system is equivalent to the ones tested already by CHSOS (Ocean Optics, BWTEK) and it will be used for pigments identification following the FORS (Fiber Optics Reflectance Spectroscopy) method. CHSOS chose a ASEQ LR1 spectrometer (300-1000 nm, 2nm resolution with 100um slit)   This spectrometer weights just 430 gr and [...]

FORS, Reflectance Spectroscopy for pigments. BWTEK mini spectrometer

2016-10-17T16:33:12+00:00

Just tested the low-cost mini spectrometer from BWTEK, Quest U (BRC112P-U). This is the most affordable of BWTEK series of  mini spectrometers. It features a 2048 pixels linear array and covers the 200 -850 nm range. This test was done in collaboration with MADATEC, an Ital­ian com­pany sup­ply­ing sci­en­tific imag­ing and ana­lyt­i­cal equip­ment also for art conservation [...]

New Pigments FORS Spectroscopy Database

2016-10-17T16:33:19+00:00

A new free online FORS spectra database of pigments is available. FORS (Fiber Optics Reflectance Spectroscopy) is a low-cost spectroscopy and it is used to identify pigments on art works. CHSOS tested an innovative miniaturized and affordable spectrometer and created the spectral database. This new paper “FORS spectral database of historical pigments in different binders” introduces [...]

Fors, Fiber Optics Reflectance Spectroscopy (for Italian readers)

2016-10-17T16:33:20+00:00

Published on Archeomatica, 1 Marzo 2014  a paper, for Italian readers, introducing the miniaturized spectrometers for Fiber Optics Reflectance Spectroscopy. This paper shows the results of the testing of a FORS (Fiber Optics Reflectance Spectroscopy) system assembled with Ocean Optics components and featuring a USB4000 miniaturized and low cost spectrometer. The small dimensions and little [...]
