How it's made: Pencils – The incredible process that makes billions of pencils!

✏️ Every year, more than 20 billion pencils are manufactured worldwide. These small objects, used for writing, drawing, measuring, or brainstorming, actually conceal a unique expertise blending chemistry, precision, and engineering. But how does the famous black or colored lead end up perfectly centered in a piece of wood?

In this exceptional documentary, we'll follow the entire pencil manufacturing process, from graphite extraction to the finished product you hold in your hand.

Discover in this video:
⛏️ The extraction of graphite, a rare mineral, from quarries and deep mines
⚒️ The transformation of the ore, ground into a fine powder for future use in mines
🧪 The preparation of the paste, a mixture of graphite, clay, and water (or pigments and binders for colored pencils)
➡️ The extrusion of the leads, where the paste is compressed under nearly 10 tons to form long, fragile rods
🔥 The successive firings, up to 1000°C, to harden the graphite leads
🕯️ The wax bath, which makes the lead smoother, more resistant, and more pleasant to use
🌲 The making of the wooden "sandwich," where the leads are inserted between two grooved cedar planks
✂️ The milling and cutting, which give the pencil its round, hexagonal, or triangular shape
🎨 The painting and Varnishing, applied in several coats to achieve a glossy and durable finish
🔤 Automatic marking, which imprints the logo, hardness, or color
✏️ Industrial sharpening, where thousands of pencils are sharpened to a point every minute
📦 Sorting, packaging, and shipping, the final step before arriving in schools, offices, and stationery stores worldwide

Between minerals, pigments, cedar wood, and precision robotics, discover how one of the most universal tools ever invented is born, produced for over two centuries using almost the same principles.
