Cindy and Beth had the unique opportunity to closely examine four works of art by important but little-known Surrealist artist Enrico Donati. With a chance to sleuth around the artist's studio overlooking Central Park, we were able to see his tools and raw materials firsthand: cans of unusual wood scraps and painting tools, bags and buckets of dense fibrous material and sand, and shelves holding a myriad of artists' paints, dry pigments, adhesives and varnishes. The samples found in the studio provided a unique insight into the wide array of supplies and techniques Donati used during the latter part of his career, and informed the technical examination reports we produced for four of his works. We chose paintings for in-depth investigation that appeared to represent stylistic transitions and development in the artist's techniques and materials. All four of the works were examined with various lighting techniques, and some of the painting materials were also sampled and examined with optical microscopy for fiber and particulate characterization. FTIR (Fourier transform infrared spectroscopy) was used to characterize some of the binders present in the various paint films.
