The manufacture of earth colours : With thirty-one illustrations

This volume offers a clear look at earth pigments—the low‑cost colours that have colored art and industry for centuries. It sorts pigments into three groups: naturally occurring minerals ready for grinding, minerals needing chemical activation, and organic‑derived hues that blend nature with synthetic chemistry. Despite their limited palette, earth colours are prized for durability and opacity.

The core of the book describes how raw earth becomes usable paint, from hand‑grinding to modern mechanised mills and chemical treatments. Detailed diagrams show each stage, from crushing stones to refining iron‑oxide by‑products into bright reds and yellows. It also explains how industrial waste can be turned into stable, vibrant pigments.

Aimed at artists, conservators and curious readers, the text balances scientific explanation with practical advice. The thirty‑one illustrations bring the machinery and mineral textures to life, making complex steps easy to visualise. Whether you mix your own paints or simply enjoy the chemistry of colour, this guide opens a window onto an often‑overlooked facet of visual art.
