Résumé
  • When Johnson & Johnson discontinued the production of the 6026 Red Cross Cotton Roll in 2004, many in the paintings conservation community were at a loss. This cotton product was a preferred cotton for surface cleaning and varnish removal, famous for its sterile quality, long fibers and handling properties. Since Johnson & Johnson's change in cotton manufacturing, paintings conservators have been searching for a suitable replacement. This research compared those characteristics that made Johnson & Johnson's 6026 Red Cross Cotton useful in conservation. A small amount of remaining cotton was compared against selected cottons to determine their effectiveness in painting conservation. The cottons were chosen from art conservation suppliers and a local drug store brand. Also tested was a sample of cotton from Robinson Healthcare of Chesterfield in the United Kingdom that had similar properties to the Johnson & Johnson cotton. All have undergone either sterile or non-sterile cotton processes.
  • Several quantitative and qualitative tests were performed on each sample. Tests included fiber identification, fiber characteristics, metallic contamination testing, absorbency, and usability testing. Fiber identification was carried out using normal and polarized light microscopy and Fourier transform infrared (FTIR) spectroscopy. Fiber characteristics examined included: texture, tear ability, trash and nep content (debris and entangled fibers), color through colorimetery readings using the CIE L*a*b System (focusing on the L* and b* measurements), and length and length uniformity. Metallic contamination testing was performed using inductively coupled plasma optical emission instrument (ICP-OES) to search for the presence of 30 metals (detects trace amounts in parts per billion). Absorbency testing was preformed using seven swabs from each sample. Each swab was tested for the ability to absorb distilled water. Swabs were weighed using an analytical balance before absorption, rolled onto a bamboo stick, dipped in distilled water, then rolled five times to remove excess water and weighed after absorption using an analytical balance. Residual water left on the balance after the wet swab was removed was also weighed. Usability testing involved testing each sample ten times which included five tests on two different canvases (one textured and one smooth) to determine varnish removal capabilities and assess the number of cotton fibers left behind on the painting’s surface. Test canvases were pre-primed commercial canvases painted with Golden carbon black acrylic paint and spray varnished with Liquitex Soluvar Gloss Varnish in mineral spirits (30%). Varnish removal was performed with pre-weighed swabs and mineral spirits. Each of the ten tests was limited to a canvas area of 1.5 inches².
