Derwent XL Charcoal

Derwent XL charcoal blocks are naturally water-soluble, opaque colors that can be layered to create even more color by adding water. Warm colors are a great way to explore new coals. The Derwent XL coal combines the natural qualities of coal with the strength and ergonomics of a sturdy block, and is great for large strokes. Dimensions: 20mm wide and 60mm long. These incredibly versatile hydrosoluble blocks create a wide range of soft, strong, agile and daring textures.
