Hi, Alex, Peter Brothers's response to my 2005 query on ARSCLIST is here: http://www.cool.conservation-us.org/byform/mailing-lists/arsclist/2005/12/msg00073.html My image is back up where it was, but because people had been hot-linking my images, you'll need to copy the URL and paste it into your browser. It didn't click for me from the cool website. Pasting the link into the browser should allow you to see the image. http://www.richardhess.com/tape/tape_crystal.jpg Good luck!
