Microscopia per l’arte. Preparazione di Cross-section.

Letture suggerite sull’argomento sono gli articoli di W. C. McCrone‘s  [1,2], che e’ un riferimento nel settore. La microscopia per l’indagine dell’arte e’ stata trascurata per dar posto a nuove  e piu’ sofisticate tecnologie, ma dai costi proporzionalmente piu’ alti [3].

Preparazione di Cross-sections

  Nel video mostro come realizzare le cross-section. Ricordo che la resina epossidica e’ tossica, quindi raccomando molta attenzione. Utilizzare guanti e mascherina. Un’utile risorsa di informazioni sulla preparazione di cross-section e’ [4].

I materiali che uso sono:

  • stereo microscope
  • EpoxiCure Epoxy Resin 20-8130-032 Buehler 0.95l
  • EpoxiCure Epoxy Hardener 20-8132-008 Buekler (o.24l)
  • 8” microcloth PSA 10/PK Buehler 693-3
  • 8” Carbimet 2 abrasive paper 600/P1200 Plain back Qty 100 PN: 30-5108-600-102
  • 8” Carbimet 2 abrasive paper 400/P800 plain back Buehler PN: 30-5108-400-102

Freelance Cultural Heritage Scientist I’m a PhD physicist and my goal is to make Scientific Documentation and Examination of Fine Art affordable to all those private collectors and small and medium museums across Europe which cannot have a scientist on their budget or buy costly instrumentation. I currently provide documentation as well as training on scientific documentation methods such as black light, infrared, reflectance transformation imaging and 3D modeling My interest is to promote the development of multispectral imaging software and hardoware tools for museums professionals and the public: ipad apps for interactive exhibits to engage public in examination and discoveries; ipad apps to examine and annotate multispectral images for painting conservation; web-server apps to examine and share multispectral images. more @ www.antoninocosentino.it
