The manuscript of A Christmas Carol by Charles Dickens was bound in crimson morocco after it was returned by printer. One of the peculiarities of that binding was that each page was silked.
As it happens, silk deteriorates faster than paper. It becomes brittle and endangers the paper. When the manuscript was brought to the conservation lab, it was decided to remove the silk. Below you can see a video, made by Reba Snyder, a conservator at the Thaw Conservation Center at The Morgan Library & Museum, that illustrates the process.
