If you walked into a book restoration lab, you might think you were in a surgery center instead of a library. The tools are that precise. We aren't talking about hammers and nails here. We are talking about tools that allow a person to move a single fiber of paper or flatten a piece of skin that has been curled for two hundred years. One of the most important tools in the kit is the bone folder. It sounds like something out of a gothic novel, but it is actually just a smooth, flat piece of animal bone, usually from a cow or a deer. Why bone? Because it is incredibly smooth and does not have the sharp edges or static electricity of plastic. When you rub it against old vellum, it does not scratch or abrade the surface. It just glides.
The bone folder is used for making precise creases. If you have a page that has been folded the wrong way for a century, you cannot just push it down with your thumb. The oils from your skin could damage the paper, and your thumb is too soft to get a crisp line. The bone folder allows you to apply even, firm pressure exactly where you need it. It is also used to burnish the edges of the binding. It is a simple tool, but in the hands of an expert, it can do amazing things. You can feel the texture of the material through the bone in a way that you just cannot with a metal tool. It is all about that tactile feedback. Do you ever just feel like you can 'read' a surface with your fingertips? That is what this is like.
At a glance
The specialized tools used in vellum restoration are designed to be gentle but effective. Here are the heavy hitters in a restorer's drawer:
- Micro-Spatulas:These are tiny stainless steel tools used for lifting up delaminated layers of paper or glue. They are thin enough to slide under a flake of paint without breaking it.
- Fine Bone Folders:Made from real bone to ensure no scratching or heat buildup during friction.
- Custom Book Presses:These are not your average clamps. They have adjustable platens that ensure the pressure is perfectly even across the entire surface of the book.
- Linen Thread and Beeswax:Used for re-sewing the signatures. The wax reduces friction so the thread doesn't saw through the old paper.
- Microscopes:Because sometimes the damage is too small for the naked eye to see.
The power of the press
Once a book has been cleaned and the pages have been treated, it usually needs to spend some time in a press. But you cannot just squash it. Vellum is especially tricky in a press. If you apply too much pressure too quickly, you can actually crush the fibers of the skin or cause the inks to transfer to the opposite page. Custom-fabricated book presses have adjustable platens—that is the flat part that touches the book—so the restorer can dial in the exact amount of weight needed. It is a slow process. A book might stay in the press for weeks as it dries out after a treatment. This ensures that the book stays flat and the new glues set properly without causing the covers to warp.
Restorers also need incredible visual acuity. That is just a fancy way of saying they need to be able to see tiny, tiny details. They look for 'foxing,' which are those little brown spots you see on old paper, or for signs of 'red rot' in leather. They look for the way the light hits the vellum to see if it is starting to flake. It is like being a detective. You are looking for clues about what happened to this book over the last 400 years. Was it kept in a damp room? Was it near a fireplace? Every bit of damage tells a story, and the tools help the restorer read that story and then fix it. It is a beautiful blend of physical skill and mental focus.
