http://news.bbc.co.uk/1/hi/sci/tech/3103354.stm No, this isn't dreadful spam. It is a link to a chap who did some experimental archeology, and came up with a dye technique "long lost" for Imperial Purple. Well, it's a link to the _story_ about the chap. Pass it on to those who would be interested. Cheers! HL Esther of Ennis Merth
