Unit II: Ink, the Scribe's Chemistry
SCROLLWORK LIBRARY · UNIT II OF VIII
Good. Your desk is ready. Now we come to the inkwell, and I warn you: ink is where scribes reveal whether they understand their craft or merely decorate with it.
An ink is not a color in a bottle. It is a small piece of chemistry that must do four jobs at once: flow from the pen, mark the page, dry without smudging, and survive. Some inks survive for millennia. Some destroy the very page they were meant to honor. The difference is chemistry, and in this unit you will learn it the way scribes learned it: by making the inks yourself.
You will mix carbon ink from soot and charcoal, and learn what gum arabic does, what viscosity means, and what a suspension is. You will brew iron gall ink from oak galls, and you will confront its beautiful danger honestly: the same chemistry that makes it darken and bite into the page is the chemistry that eats manuscripts from the inside. You will grind the reds of rubrication, minium and madder and the rest, and learn why the word miniature has nothing to do with smallness. And you will finish with the physics of the line itself: capillary action, feathering, bleed-through, sizing, and the conservator's long view. The unit ends with a question worthy of a scribe: choose your ink for a book meant to last five centuries, and defend the choice.
Handle the toxic pigments with respect. Minium and vermilion are studied, never made. The lessons say so, and I mean it.
Unit Learning Objectives
By the end of this unit, scholars will be able to:
- Mix a functional carbon ink and explain the roles of carbon, water, and binder.
- Describe the three ingredients of iron gall ink, explain oxidation, and explain ink corrosion honestly.
- Name four historical red pigments and their sources, and explain what rubrication did in medieval books.
- Explain capillary action, feathering, bleed-through, and sizing, and how each shapes the written line.
- Compare how parchment, sized paper, and unsized paper receive the same ink.
- Choose an ink for a five-century book and justify the choice with chemistry and conservation.
In This Unit
Mix a working carbon ink and learn what gum arabic, viscosity, and suspension do for the line.
The chemistry of iron gall ink: why it darkens after writing, why it corrodes the page, and the trade between permanence and preservation.
Lesson 7: Red Inks & Rubrication
How red became information in medieval books, from minium to madder, and why "miniature" comes from a red pigment, not from smallness.
Lesson 8: Ink Flow & Preservation
Capillary action, drying, and decay: how the line gets onto the page, and how the page survives the line.
The Unit II Quiz closes this unit. You will find it, with its download, at the end of Lesson 8: Ink Flow & Preservation.
What Scholars Will Practice and Make
Three working inks, mixed by hand: carbon, iron gall (or its safe household analogue), and red. Ink flow and line-quality evaluations on ordinary paper. A rubricated page where red carries meaning. And the unit's final judgment: your reasoned ink for the five-century book.
Ink is ready. The desk is ready. Now the instrument that carries one to the other. Unit III is the quill: the feather, the cure, the cut.
