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.

Ultramarine [Blue]
- Pigment code
- PB29
- Type
- inorganic
- Chemical name
- complex silicate of sodium and aluminum with sulfur
- Chemical formula
- Na8-10Al6Si6O24S2-4 or Na6-8Al6Si6O24S2-4
- Properties
- Ultramarine is the standard warm blue, a brilliant blue pigment that has the most purple and least green in its undertone. It has a moderate to high tinting strength and a beautiful transparency. Synthetic Ultramarine is not as vivid a blue as natural Ultramarine. Ultramarine dries slowly in oil and tends to produce clean, though granular, washes in watercolor. French Ultramarine mixes well with Alizarin colors in oil and watercolor form to create a range of purples and violets. It can dull when mixed with white in acrylic form, but mixes well with other colors. The shade varies based on manufacturer. Considered a great color for glazes, it is not suitable for frescoing.
- Permanence
- Ultramarine has excellent permanence, although synthetic Ultramarine is not as permanent as natural Ultramarine. It may discolor if exposed to acid because of its sulfuric content.
- Toxicity
- Ultramarine has no significant hazards.
- History
- The name for this pigment comes from the Middle Latin ultra, meaning beyond, and mare, meaning sea, because it was imported from Asia to Europe by sea. It is a prominent component of lapis lazuli and was used on Asian temples starting in the 6th century. It was one of the most expensive pigments in 16th century Europe, worth twice its weight in gold, and so was used sparingly and when commissions were larger. Ultramarine is currently imitated by a process invented in France in 1826 by Jean Baptiste Guimet, making blue affordable to artists and extending the range of colors on their palettes.
