- Résumé
- "Many conservation labs have made the switch to disposable nitrile gloves for handling metals. Nitrile gloves are impermeable to the damaging residues from our skin and provide better grip than cotton. Based on methodology developed in a research project carried out at Queen’s University by William Hoffman in 2009, concerns about the effects of sulfur-containing accelerators on silver were investigated by testing four nitrile gloves. Accelerators are commonly used additives in the manufacture of nitrile gloves, but their use can be avoided if a combination of other additives performs the same cross-linking function. The four gloves included three standard nitrile gloves and one accelerator-free nitrile glove: Ansell TouchNTuff® Disposable Nitrile Gloves, Kimberly-Clark™ Purple Nitrile Powder-Free Exam Gloves, Showa Best™ NDEX ™ Medical nitrile gloves, and Showa Best™ N-DEX™ Free nitrile gloves. Experiments included the silver nitrate test for chlorides, the sodium azide test for reduced sulfur, Fourier Transform infrared spectroscopy of gloves and transferred residues, and Oddy-style accelerated ageing. Of the four nitrile gloves tested, two tested positive for chlorides, three tested positive for reduced sulfur, and three transferred residues that had visible impacts on metal coupons in high heat high relative humidity accelerated ageing conditions. The effects of the residues on silver, sterling silver, and copper are discussed."
