Here are some specific details about Copley's materials and techniques:
* Oil paints: Copley used high-quality pigments, carefully ground and mixed with linseed oil.
* Canvas: He often used fine linen canvas, which provided a smooth surface for his detailed brushwork.
* Glazing: Copley frequently employed glazing, a technique involving thin layers of transparent paint applied over the base layers to achieve subtle variations in color and depth.
* Scumbling: He also used scumbling, a technique involving applying opaque paint in a thin, dry brushstroke, to create textural effects and subtle transitions in color.
Copley's use of these materials and techniques contributed to his distinctive style, characterized by its realism, naturalism, and rich, nuanced color palettes.
