About this product range

Schmincke Horadam Gouache is more than just opaque watercolor. Since no white is added to Horadam Gouche to artifically boost its covering power, it can create crisp color blends like no other gouache. Of the 48 colors, all but 8 are based on a single pigment.

Like Horadam Watercolors, colors thin with water and are easily rewetted if left to dry on the palette. Horadam Gouache is so finely ground, it can even be used for 0.15 mm airbrush work.

Many other brands of gouache are "designer" gouaches, with an emphasis on accurate pre-mixed colors for use by the designer. By contrast, Horadam is a "fine artist" gouache, with an emphsis on providing the classic range of pigments as pure, single-pigment colors.

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.
