Titanium White, or Titanium Doixide, is an artificial mineral pigment introduced in the 1920s. It is valued for its opacity, good lightfastness, and stability in all media. Its high tinting strength can render it a dominant colour in mixtures. It is very slow drying in oil, and creates a somewhat brittle paint film, though more flexible than Zinc White. Its brightness makes it a popular addition to gesso.

Burnt Sienna is a natural earth pigment that has been in use since antiquity. Our Burnt Sienna comes from Tuscany, and is produced by calcining Raw Sienna to temperatures of about 450 degrees Celsius. This process creates a rich warm colour and increases transparency. It also offers a good tinting strength, excellent lightfastness, and a fast to medium drying rate in oil. It is stable in all media but, like umber pigments, may be difficult to disperse in acrylic binders.

Raw Sienna is a natural earth pigment that dates back to antiquity. Our Raw Sienna comes from areas of Tuscany where the earth has been coloured by iron-rich minerals. It provides a good tinting strength, excellent lightfastness, and a fast to medium drying rate in oil. It is stable in all media but, like umber pigments, can be difficult to disperse in an acrylic binder. It is similar in composition to Yellow Ochre, but whereas Yellow Ochre contains a higher proportion of clay, Raw Sienna contains a higher proportion of silica. As a natural material, the exact colour and qualities of the resultant pigments can vary, but generally this difference creates a paler, more opaque Yellow Ochre, and a darker, more transparent Raw Sienna.

Ultramarine Blue Dark is an artificial mineral pigment that is produced by heating clay, soda, sulphur and coal to high temperatures. Its name comes from outremer, or over-the-sea, as a reference to the highly-prized Lapis Lazuli pigment which had been imported into Europe from Afghanistan since the Middle Ages. First manufactured in France and Germany in 1828, synthetic Ultramarine provided a brilliant and affordable blue to artists, and it remains one of the most popular blues on artists' palettes today.

It is a transparent pigment, with a high tinting strength and excellent lightfastness. It reacts to alkali, therefore it is not suitable for use in lime-fresco; we do offer a Limeproof Ultramarine Blue for this purpose. It is stable in all other media, although it can be tricky to grind in oil. Instead of creating a thick, buttery paste, it can remain stringy and deteriorate when stored in a tube. To correct this, many commercial paint manufacturers include additives and waxes in their recipes; if you intend on grinding your own paint, you could try replacing 10-15% of your Linseed Oil with Poppy Oil to improve the consistency. Ultramine Blue provides a slow-drying, fairly hard paint film, which can tend towards brittleness.

Smalt is a kind of cobalt blue glass or frit, and its use as a pigment dates from the 1600s in the glass-making regions of Saxony. We offer two shades, light and dark, which are determined by the particle size of the pigment; the more finely ground the powder, the paler the colour. Before the introduction of Ultramarine Blue, Smalt was available in a wide variety of grades. It is a very transparent pigment, which is easily overwhelmed in mixtures due to its weak tinting strength. It works best in water based media. When ground in oil, it can become almost invisible in dried oil-paint films because its refractive index is so close to that of linseed oil.
