Gypsum is powdered Calcium Sulphate, a traditional ingredient in gesso grounds used in southern Europe. One of the advantages of preparing your painting surface with gypsum is that it allows for a particularly even absorption of the paint film. It can also be added to acrylic primers to increase absorbency or add tooth to a surface. Learn More

Genuine Indigo is a natural vegetable pigment derived from the Indigofera Tinctoria plant, which was first imported into Europe from India in the seventeenth century. It replaced woad, which had been grown natively in Europe for its blue dye. The leaves are soaked in water to ferment; upon drying, an oxidised residue forms on the dry leaves, which is removed, washed, boiled in water, and then dried to form cakes of pigment or dye.

Indigo is very transparent, with a good tinting strength. It requires a wetting agent to disperse, and in oil it dries very slowly. It is fugitive to light; this drawback means that it is no longer commonly available in commercial paints. It fell out of general use at the beginning of the seventeenth century, largely replaced by Prussian Blue, and synthetic Indigo was patented in the 1890s. However, it provides a subtle shade of blue that is still desirable in works that are going to be protected from light.

Yellow Ochre is a natural earth pigment that has been in use since prehistoric times. It is derived from iron-rich clay deposits that are present all over the world; our Yellow Ochre comes from the hilly regions around Verona, Italy. As a pigment, it is semi-opaque, extremely lightfast, and stable in all media. It has a medium to slow drying rate in oil, creating a tough, flexible paint film. Yellow Ochre is similar in composition to Raw Sienna, 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 compositional difference creates a paler, more opaque Yellow Ochre, and a darker, more transparent Raw Sienna.

Verdigris is an artificial pigment that dates from antiquity. Originally, it was produced by exposing copper to vinegar; nowadays acetic acid is used. It is acidic, so can contribute to the deterioration of paper supports. For this reason, it is more suited to oil or tempera painting than it is to watercolour. In tempera painting, it should be bound in animal glue or isinglass glue rather than egg york. When used in oil painting it should be held in a resin oil or balsam such as Venice Turpentine, as it can turn brown when ground directly into linseed oil. It is a fast-drying, transparent pigment, with a visible crystalline structure.

Potter's Pink is an artificial mineral pigment produced by roasting tin oxide with various other oxides. It was first discovered in the pottery region of Staffordshire in the late-1700s, and in the following century Winsor & Newton introduced Potter's Pink into their watercolour range under the name "pink colour". It went on to become a popular addition to watercolour palettes, offering an opaque, lightfast colour with a weak tinting strength and a medium level of oil absorption.

Colophony is a by-product of the distillation of turpentine. It is soluble in most solvents, but considered an adulterant in varnishes and paints, as it forms a weak surface that is prone to darkening and cracking. It is, however, a key ingredient in wax-based etching grounds, imparting hardness, and can be used in powdered form (rosin) to make aquatints. Learn More

Burnt Umber is a natural earth pigment from Italy, composed of iron oxide, manganese, and aluminium silicate. It is a form of Raw Umber that a has undergone a process of calcination, becoming warmer, more transparent and easier to disperse. It has a good tinting strength, and is very lightfast, quick-drying, and stable in all media. In oils it forms a hard, fairly flexible paint film, though it may be difficult to use in acrylic mediums.

Terre Verte, sometimes known as Green Earth, is a natural earth pigment derived from clay coloured by iron silicate. As with other natural pigments, impurities can prevent it from fully dispersing in an acrylic binder, although it is a popular pigment in all other mediums. It has been in use since antiquity, providing excellent lightfastness and great transparency, with a low tinting strength. It requires a high volume of oil, and dries slowly to create a soft, flexible paint film. When calcined, Terre Verte becomes Burnt Green Earth.
