wool, the amazing thing about it is that it has wool samples in it that are affixed with red sealing wax! So not only do you have the color preserved between the pages with the recipe and variables like time, etc. - you have a real sample that can be chemically tested either nondestructively or destructively with tiny hair like samples removed. That is a TREASURE.
This book is owned by the Getty Research Institute and there is a wonderful blog about the book by Karin Leonhard (Research Scholar, MPIWG) and David Brafman (Curator for Rare Books, Getty Research Institute) that I will let you read instead of paraphrasing.
And even better for any of you who get really interested and 'geek-ed' out by stuff like this, the entire manuscript has been photo graphed and put up on the Getty site for researchers. It is a bit clunky to go through, but fun none the less.
