What Materials Did Leonardo Use In His Notebooks?

Da Vinci’s notebooks feel like a peek into his restless mind, and the tools he used were as inventive as his ideas. He favored paper made from cotton or flax—durable stuff—and wrote with a sharpened quill dipped in iron gall ink. For sketches, he’d switch to silverpoint, dragging a thin metal stylus across prepared paper coated with ground bone or pigment. The lines started faint but darkened over time, giving his drawings this ghostly precision. Occasionally, he’d add touches of colored chalk or dilute ink for shadows. The fact that these materials let his work survive 500 years is a testament to both his skill and the quality of Renaissance craftsmanship. Holding a facsimile of one of those pages, you can almost smell the iron and vinegar from the ink.

Leonardo da Vinci's notebooks are a treasure trove of his genius, and the materials he used were pretty fascinating for his time. He primarily wrote on loose sheets of paper or in bound notebooks made from linen rag paper, which was the standard back then since wood pulp paper wasn’t common yet. The ink he used was iron gall ink—a mix of tannic acids from oak galls and iron salts—which gives that rich, dark brownish-black color you see in his sketches. For his drawings, he often used metalpoint (a precursor to graphite pencils) or charcoal, especially for preliminary sketches. Sometimes, he’d even layer red chalk or ink washes for shading. The coolest part? Many of his notes were written in mirror script, probably out of habit or to keep his ideas semi-private. Flipping through those pages feels like unlocking a secret vault of Renaissance brilliance.

What’s wild is how durable his materials were despite their age. The linen paper held up remarkably well, and the iron gall ink, while corrosive over centuries, stayed legible. Some pages even show his revisions—scratches or smudges where he adjusted designs, like the helicopter or anatomy studies. You can almost picture him hunched over, scribbling furiously with a quill, completely absorbed in his work. It’s humbling to think these fragile sheets survived wars, time, and neglect to land in museums today. Makes you wonder what else he might’ve jotted down in lost notebooks.
