About this product range
These artist grade watercolors continue the Blockx family legacy that began in 1865. They are made using the same processes developed many years ago. Only the finest ingredients go into the manufacture of Blockx watercolors. Rare, tough pigments are ground slowly and repeatedly on stone mills to achieve the optimum particle size, and to eliminate overheating and iron pollution. The pigments are then blended with pure, light gum Arabic, honey made from selected flowers, and chemically pure glycerin and water. The result is a variety of stable, transparent colors with wonderful working properties.
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.
Cadmium Yellow
- Pigment code
- PY35
- Type
- inorganic, cadmium
- Chemical name
- cadmium zinc sulfide
- Chemical formula
- CdZnS
- Properties
- Cadmium Yellow is brilliant, dense, and opaque, with good tinting strength and very high hiding power. It is the artist's principal bright yellow and is available in light, medium, and dark shades. The deeper shades appear deep orange and have the greatest tinting strength. It is slow-drying in oil form and is used in both oil and watercolor form. A clean Cadmium Orange is created when Cadmium Yellow is mixed with Cadmium Red. Hues vary by brand. Cadmium pigments have been partially replaced by azo pigments, which are similar in lightfastness to the cadmium colors, cheaper, and non-toxic. Cadmium Yellow is usually available in a pure grade, or in a cadmium-barium mix. This mix has the same permanence with a lower tinting strength.
- Permanence
- Cadmium Yellow is lightfast and permanent in most forms, but like most cadmium colors, it will fade in fresco or mural painting. The deeper shades are the most permanent. The pale varieties have been known to fade with exposure to sunlight in conditions where moisture is able to penetrate the binder.
- Description
- Aurora Yellow, Cadmium Primrose Yellow, Cadmium Zinc Yellow, Lemon Yellow, Primrose Yellow. Deep Cadmium Yellow is sometimes called Orient Yellow.

Cadmium Orange
- Pigment code
- PO20
- Type
- cadmium
- Chemical name
- cadmium sulfide and cadmium selenide
- Chemical formula
- CdS x CdSe
- Properties
- Cadmium Orange was the first true orange and was made by mixing Cadmium Yellow with Cadmium Red. It is a pure hue with excellent opacity and low toxicity compared with its predecessors. It also has very high hiding power. The greatest tinting strengths are possessed by the deeper shades. Only the highest grades contain pure Cadmium Orange without barium mixed in it. Cadmium pigments have been partially replaced by azo pigments, which are similar in lightfasness to the cadmium colors, cheaper, and non-toxic.
- Permanence
- Cadmium Orange has excellent permanence, but like many cadmium pigments, it will fade in fresco or mural painting. The deeper varieties of this pigment are the most permanent. The paler varieties have been known to fade when exposed to sunlight.
- Toxicity
- Cadmium Orange is a known human carcinogen. It is extremely toxic if inhaled and slightly toxic if ingested.
- History
- Cadmiums get their names from the Latin word cadmia, meaning zinc ore calamine, and the Greek word kadmeia, meaning Cadmean earth, first found near Thebes, the city founded by the Phoenician prince Cadmus. Metallic cadmium was discovered in 1817 by Friedrich Strohmeyer. It was used sparingly after its discovery due to the scarcity of cadmium metal.
Zinc White
- Pigment code
- PW4
- Type
- inorganic
- Chemical name
- zinc(II)-oxide
- Chemical formula
- ZnO
- Properties
- Zinc White is the coolest white, and it has a cold, clean masstone and a slightly bluish tint. It has less hiding power and is more transparent than other whites. It dries slowly and is good for painting wet into wet and for glazing and scumbling. Zinc White is neither as opaque nor as heavy as Lead White, its covering power is not as good, and it takes much longer to dry. However, it does not blacken when exposed to sulfur in the air as Lead White does. It is very valuable for making tints with other colors. Unmixed Zinc White dries to a brittle and dry paint film that may crack over the years, so it is not good for frescoing. It is more transparent in acrylic form than Titanium White and is the most commonly used white with gouache. Chinese White is a version of Zinc White appropriate for opaque watercolor techniques.
- Permanence
- Zinc White has great permanence and lightfastness.
- Description
- Chinese White, French White, Permanent White, Silver White, Snow White, Zinc Oxide.
