About this product range
- Legendary professional-quality oil colors
- Majority of range is mono-pigment
- High pigment loads and the finest linseed/poppyseed oils
- Maximum tint strength and lightfastness
- Stone ground for optimal pigment integrity
Family-made in Belgium for over 140 years, Blockx Oil Colors are hand-ground up to four times on slowly rotating stone mills for perfect pigment integrity and the purest possible color experience. This time-honored production method results in a range of luminous, ultra-smooth oil colors that rank among the world’s very best.
Still crafted using Jacques Blockx’s original formulas, maximum concentrations of the purest pigments guarantee unparalleled brilliance. Iron oxides, earths, and blacks are ground with linseed oil — the rest of the range is ground with non-yellowing poppyseed oil, which results in noticeably brighter, more intense color and cleaner mixtures.
Entirely free of additives or fillers, Blockx Oil Colors carry the highest possible lightfastness ratings. The range consists primarily of single-pigment colors, and each is meticulously tested to uphold the legendary quality that has attracted artists like René Magritte, Salvador Dalí, and Frank Stella. Historical pigments — including Vermilion, Naples Yellow (Light and Dark), and Lapis Lazuli — expand the range for those seeking timeless hues.
An investment in Blockx means investing in the very finest materials for your art, safeguarding its integrity for generations to come.
