Unit IV: Pigment, Print & Seals
CREATIVE ARTS WORKSHOP · UNIT IV OF VII
Cloth held the soft goods. This unit holds the marks.
Everything scholars have made so far can be carried, worn, or bound. What it cannot yet do is repeat itself. A mark made once, by hand, belongs to one object and one afternoon. Pigment ground true, a stamp cut square, a seal pressed into warm wax: these are the tools that let a maker's mark travel, onto ten labels, a hundred pages, a jar that must say whose it is and prove it has not been opened. This unit teaches scholars to make marks that can be trusted at a distance.
The unit begins at the oldest bench in the workshop, a stone for grinding color, where paint starts as rock and earth and a scholar learns that grinding is patient work with a safety record of its own. Then the stamp: printing's ancestor was not a press but a seal, rolled or pressed into clay thousands of years before paper, and scholars work from foam stamps up to a first linocut under strict tool discipline. Last, the seal itself as an instrument of identity: the matrix cut in reverse, the wax that shows tampering, and the reusable wax tablet, the ancient world's notebook, built as this unit's closing make.
Unit Learning Objectives
By the end of this unit, scholars will be able to:
- Grind and mull a safe pigment into paint, and name the binder that makes a pigment into a paint.
- Explain the long history of color, from ochre ground a hundred thousand years ago to the first pigment human beings ever manufactured.
- Name the famous historical pigments that are poisonous, say what each contains, and choose the modern safe substitute for each.
- Keep a labeled color chart that another scholar could use to reproduce a color exactly.
- Print an even run of impressions from a stamp, and describe how printing grew out of seal craft.
- Cut a simple seal matrix in reverse, seal with wax, and build a wax tablet and stylus in the Roman manner.
In This Unit
Lesson 15: Pigments, Paints & Color Charts
Ochre at a hundred thousand years, Egyptian blue, binders from gum arabic to egg yolk, the poisonous shelf taught as history, and the color chart that makes a recipe repeatable.
Lesson 16: Printmaking, Stamps & the Label Station
Cylinder seals as printing's ancestors, the Diamond Sutra of 868, foam stamps and a first linocut, and a working label station for jars, specimens, and the Gazette.
Lesson 17: Seal Matrices & Waxwork
Stamp seals of the Indus cities, medieval matrices and the wax that guarded documents, cutting a design in reverse, and the wax tablet as the unit's closing build.
The Unit IV Quiz closes this unit. You will find it, with its download, at the end of Lesson 17: Seal Matrices & Waxwork.
What Scholars Will Practice and Make
A practice batch of paint ground and mulled by hand from a safe earth pigment, painted out into a labeled color chart that becomes the scholar's standing reference for every color mixed afterward. A foam stamp printed ten times in a row, pressure and ink adjusted until the impressions match, followed by runs of real labels for real jars. A practice seal carved in a potato or an eraser and tested in wax before any true matrix is cut. And the closing make: a framed wax tablet with its own stylus, smoothed and reused until writing on it is second nature.
Every drill in this unit runs on practice material first. Pigment is ground small and wet, blades cut scrap before lino, and wax seals are pulled on waste paper until the hand knows the pressure. A spoiled swatch or a smeared impression costs nothing. A habit learned carelessly costs every mark after it.
Marks learned, Unit V goes outdoors and down to the earth: garden tools, clay in both its lessons, the plant press, and the structures a garden asks a builder to raise.
