About this product range

Blockx Soft Pastels are handmade in Belgium using pure pigments in the same tradition started by company founder and chemist Jacques Blockx in 1844. Four subsequent generations of Blockx family members have combined traditional methods with modern chemistry to create artist's colors that are pure, permanent, lightfast, and stable.

Colors are named in such a way as to make it easy for artists to choose the exact shades they need. For example, Apple Green's five shades are: Apple Green 641, Apple Green 642, Apple Green 643, Apple Green 644, and Apple Green 645.

If the color name ends in:

1 — the pure color is upgraded with black
2 — this is the pure color
3 — the pure color is tinted with white
4 — the pure color is tinted with more white
5 — the pure color is tinted with much more white

These watersoluble pastels are soft and velvety in texture, possess a superb tinting strength, and will draw on any surface, although they're best-suited for pastel paper.

Individually wrapped pastel sticks are 2-1/2" L x 1/2" Dia (65 mm x 12 mm).

Pigment information

General reference notes about pigments can describe other media (such as oil). They do not verify this product’s exact formulation or behavior.

Mars Black

Pigment code: PBk11
Type: earth
Chemical name: iron oxides
Chemical formula: FeO or Fe2O3
Properties: Mars Black is an opaque black with a strong and cool masstone, a slightly warm tint, and a warm brown undertone. It is not as black as Ivory Black, but it dries more quickly and has three times the tinting strength. Mars Black is normally the only black available in acrylic form and that is safe to over paint. It can be used in all media without reservation and is widely used as an alternative to Lamp Black and Ivory Black.
Permanence: Mars Black is very lightfast with excellent permanence.
Toxicity: Mars Black has no significant hazards and is the only major black pigment considered non-toxic.
History: The word Mars refers to the Roman god of iron and war. Mars Black was developed in the early 20th century from inorganic, synthetic iron oxide.
Description: Black Iron Oxide, Iron Black, Magnetic Oxide, Mapico Black, Mineral Black. Sometimes labeled as Vine Black.

Titanium White

Pigment code: PW6
Type: inorganic
Chemical name: titanium dioxide
Chemical formula: TiO2
Properties: Titanium White is the most brilliant of the white pigments. It is considered an all purpose oil color useful in all techniques and the best all around white. Its masstone is neither warm nor cool, placing it somewhere between Lead White and Zinc White. It is less prone to cracking and yellowing than Lead White, but it still yellows easily. Titanium White dries slowly in oil form, more slowly than Lead White but more quickly than Zinc White. It is opaque in oil and acrylic forms and semi-opaque in watercolor form. This pigment has good chemical stability, and its tinting strength is superior to both Lead White and Zinc White.
Permanence: Titanium White has excellent permanence and lightfastness.
Toxicity: Titanium dioxide is highly stable and is regarded as non-toxic.
History: Titanium is the ninth most abundant element in the Earth's crust, however mineral deposits that are economical to mine are less common. Titanium dioxide was first discovered in 1821, although it could not be mass produced until 1919. Widespread use of the pigment began in the 1940s. Since that time, it has become the most commonly used white pigment. The name comes from the Latin word Titan, the name for the elder brother of Kronos and ancestor of the Titans, and from the Greek word tito, meaning day or sun.

Yellow Iron Oxide

Pigment code: PY42
Chemical name: iron(III)-oxide, hydrated
Chemical formula: Fe2O3 • H2O
Properties: Yellow Ochre provides artists with earthtones from cream to brown. It has good hiding power, produces a quick drying paint, and can be safely mixed with other pigments. Its transparency varies widely from opaque shades to more transparent ones, which are valued for their use as glazes. If gypsum is present, Yellow Ochre is not suitable for frescoing. (See Brown Ochre, PY43.) PY42 is made from synthetic iron oxides. PY43 is made from natural iron oxide.
Permanence: Yellow Ochre has excellent permanence because ochres are some of the most permanent pigments available.
History: Ochre comes from the Greek word ochros, meaning pale yellow. It was one of the first pigments to be used by human beings, and evidence of its use has been found at 300,000 year old sites in France and the former Czechoslovakia.
Description: Chamois, Iron Yellow, Mars Orange, Mars Yellow, Minette, Ochre, Sil, Yellow Earth, Yellow Ochre, Yellow Oxide. Varieties of Yellow Ochre include Brown Ochre, Flesh Ochre, Roman Ochre, Spruce Ochre, and Transparent Gold Ochre.
