The authors propose an evaluation method of textiles antiquity that could be applied to the Shroud. This paper was presented in the Symposium held by CIELT (Centre International d'Études sur le Linceul de Turin) in Rome - June 10th-12th 1993
What's very interesting is the article published earlier this year ( 2011 ) in the WSJ on the same topic applied to silk age on Egyptian mummies. I can't find the paper, but I remember how interesting it was to find anyone using polarimetry these days of intense genetic research.
