Introduced in 1989, Daniel Smith professional quality Original Oils have exceptionally strong pigmentation, a uniform buttery consistency and excellent value. Intended to offer remarkable color strength, reliable lightfastness and consistent texture. Daniel Smith starts with the finest pigments, both traditional and modern. The manufacturing process is simple and traditional, batches are small, allowing paintmakers close control of every factor involved. Each batch of color is made, start to finish, by the Daniel Smith manufacturing crew in Seattle, Washington and tested by their full-time chemist throughout the manufacturing process to ensure the highest quality for every tube of Oil Paint. Daniel Smith uses a high-grade alkali-refined linseed oil that's light in color, low yellowing, with low acid value with good adhesion (except Mixed White, Titanium White and Zinc White which are mixed with non-yellowing safflower oil).
