From the Dead Sea scrolls and ancient tefillin analyzed using a cyclotron at UC Davis we can see that originally scribal ink was carbon-based. Soot was gathered from burning vegetable fats, mostly olive oil. Charcoal dust was produced by burning vegetable matter such as beech trees or cedars. Often, a glass plate was suspended over the burning materials, and the gathered soot was scraped off for use.
