Viridian Green is a synthetic inorganic pigment, similar in composition to Chromium Oxide. However, unlike Chromium Oxide, Viridian contains water molecules within its crystal structure, imparting a greater degree of transparency. Sometimes referred to as Verte Eméraude, Viridian was discovered in France in 1838, patented in 1859, and made available in the UK in 1862. It is stable in all media, and offers excellent lightfastness and good tinting strength. It requires a high oil content, and dries slowly to form a hard, fairly flexible paint film.

Cinnabar, composed of mercuric sulphide, is a mineral pigment found in crusts or veins in sites of volcanic activity. It has good tinting strength and opacity but, like many red pigments, it dries very slowly in oil media. Due to its high toxicity, it is no longer an ingredient in commercial paints, but is a prominent colour in historical palettes.

Generally, Cinnabar refers to the natural mineral, while Vermilion refers to the synthetic pigment. Cinnabar has been mined since at least the tenth millennium BC, and used as a painting material, gemstone, and ritual object by many cultures around the globe.

Gamblin Solvent-Free Fluid is an oil painting medium created by the American company Gamblin. They write:

"Gamblin Solvent-Free Fluid painting medium gives oil colours more flow and transparency. It has a moderately fast drying rate and increases gloss. Made from safflower oil and alkyd resin, Gamblin Solvent-Free Fluid is non-toxic and contains no Gamsol or petroleum distillates. To ensure proper drying and prevent beading-up of paint layers, Solvent-Free Fluid should be used in moderation with oil colours – no more than 25% by volume. To avoid wrinkling, apply mixtures of Solvent-Free Fluid and oil colors thinly. For underpainting, we recommend adding Gamsol to Solvent-Free Fluid."

Raw Umber Greenish is a natural earth pigment composed of iron oxide, manganese, and aluminium silicate. It has its roots in the Umbria region of Italy, and was historically a popular colour for underpaintings, as it dries very quickly. It is semi-opaque, very lightfast, and stable in all media but may be difficult to disperse in acrylic. It requires a large amount of liquid when mixed with oil.

Isinglass is derived from the dried swim bladders of fish, with Salianski Isinglass being the highest grade available. In the Russian Icon tradition, it commonly provided the glue component in gesso recipes, and was sometimes mixed with pigment to make tempera paints, due to its high binding strength. It can be used to make a pale, clear glue, which is less prone to darkening than other animal glues, and which is particularly flexible, making it a useful material for repairing textiles.

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.

Solid artists' quality oil paint sticks. (Ø = 3/4 ; length = 5" ) SENNELIER Extra-Fine Solid Oil Sticks can be used alone or in combination with to oil colours in tubes. The oil stick colours can be used for an entire painting. They are applied directly to any traditional oil-painting support, such as canvas, wood panel or fine art paper. They need the same archival priming (acrylic gesso or oil ground) that oil paint requires. Surfaces: Before use, the surface film of the oil stick must be peeled off. It will form again after a few days of non-use, protecting and conserving the color. The oil sticks must be applied in a thin film application of no more than 1mm thick. Once applied they can be painted over with oil stick or oil paint and if desired be diluted with turpentine. Oil stick Medium, a colorless oil stick, may be used to produce transparent effects and glazes. Once applied, the oil stick surface will dry in 2 to 5 days, depending on the atmospheric conditions Varnishing: If varnishing is desired, you must wait 6 months (as in traditional oil paint) until the colour is completely dry, before giving the painting a final coat of picture varnish. Use a soft brush to varnish so that the oil stick marks are not disturbed. SENNELIER Extra-Fine Solid Oil Stick colours are either opaque (O) or transparent (T) depending on the nature of the pigment in each colour. Oil Sticks do not change during storage and require no special precautions except to be kept away from any source of heat, which could adversely affect the stick. Application Techniques After applying the colour with the point or the edge of the oil stick, colours can be mixed directly on the support using the following methods: • Blending, with brush, finger, or drawing stump. With or without turpentine • Wash-drawing, dilute colours with turpentine or mineral spirit • Retouching, with oil stick, palette knife or brush • Textures, thick application oil stick colour. Retouch with a brush or palette knife •Sgraffito, scratching a layer of fresh paint with a point (brush handle, palette knife, etc.) to reveal the layer below. Sgraffito is related to engraving, and is used not only for revealing the under-layers of paint but also to scratch and clean unsatisfactory parts of the painting •Interior Decoration, on glass, ceramics etc. Use for decorative purposes only Learn More

Prussian Blue is a synthetic organic pigment that was discovered by the paint maker Diesbach, apparently by accident, in Germany in the early eighteenth century. For many years, it was used not only as a colour in its own right, but also as a component of the original Hooker's Green. The other ingredient, gamboge, is highly fugitive, which is why many watercolours painted with Hooker's green have taken on a bluish tone with with age.  

It is a very transparent and heavily staining colour. It dries quite quickly in oil, and can therefore wrinkly if applied too quickly. It is suitable for use in oils, watercolour, and egg tempera. However, it shouldn't be used in conjunction with alkali substances, such as Lead White or Calcium Carbonate as it can turn brown, so it isn't suitable for fresco. For the same reason, it isn't used with acrylic resin binders due to their alkaline nature, so most paint manufacturers will replace Prussian Blue with a mixture of Phthalo Blue and black in their acrylic ranges. It requires a wetting agent to fully disperse into a binder.

Linseed Oil is derived from flax seeds, and appears on our shelves in many guises: Cold Pressed, Refined, Stand Oil, and as a key ingredient in many mediums. It has been appreciated for its drying properties since the Medieval period, and has become the most popular oil used in painting today due to the strong, flexible and glossy film that it creates. Cold Pressed Linseed Oil is ideal for the grinding of pigment to make oil paints. The process of producing Cold Pressed Linseed Oil results in a lower yield, but the resultant oil is of a superior quality to oil that has been extracted by other methods, creating a paint film that is more resistant to embrittlement on aging. Its yellow colour is caused by the high concentration of linolenic acid, the presence of which provides durability to the paint film. The amount of oil that each pigment requires can vary enormously. Alizarin Crimson, for example, requires a high percentage of oil compared to most other colours. We would always recommend mulling the pigment and oil together thoroughly to create a "short" or buttery paste, with evenly dispersed, well-coated pigment particles. This process contributes to the strength and flexibility of the paint film, and prevents the inclusion of excess oil. Origin: USA Learn More

Michael Harding Non-Absorbent Acrylic Primer (NAAP) is a versatile product suitable for application on various surfaces, including linen, wood, MDF, and more. It is designed to create a robust, flexible, permanent, and intensely pigmented ground, making it an excellent choice for both acrylic and oil paints. Important Application Guidelines: Support Selection: NAAP should not be applied over surfaces treated with rabbit skin/hide glue or on unsound, flimsy supports such as cardboard. Opt for stable substrates to ensure the primer’s effectiveness. Not a Gesso: Please note that NAAP is a primer, not a gesso. As such, there is no need for additional gessoes, sizes, or other ancillary products when using NAAP. DIRECTIONS: Coat Application: Apply a minimum of two coats of NAAP to your chosen support, ensuring liberal coverage for optimal results. Dilution for Flow: If you desire increased flow, dilute NAAP with a mixture of 1 part water to 4 parts NAAP. This adjustment allows for customization based on your artistic preferences. Second Coat Application: Apply the second coat once the first coat is touch dry, typically after approximately 1 hour. This step contributes to the creation of a well-prepared painting surface. Additional Considerations: Suitable Supports: Do not use Michael Harding Non-Absorbent Acrylic Primer on flimsy or unsound supports. It is crucial to choose a stable and well-prepared surface for priming to ensure the longevity and integrity of your artwork. Canvas Weave Consideration: Avoid using this primer on canvases with a wide weave. The non-absorbent nature of the primer may not be suitable for canvases with a loose or open structure, compromising its effectiveness. Transparency Check: Before application, inspect your canvas material by holding it up to the light. If you can see light passing through the wefts (threads) of the canvas, it is not recommended to use Michael Harding Non-Absorbent Acrylic Primer. Opt for a more appropriate primer based on the transparency of your canvas. Learn More

Casein is a protein derived from dried milk, which has been used in painting since ancient times. It can be combined with Ammonium Carbonate to form an emulsion, which acts as a durable, non-resoluble binder for pigments, producing a matte, fast-drying paint, similar in appearance to egg tempera. We use casein as a binder for our L. Cornelissen & Son Pigment Colour Charts, as it is a medium that clearly showcases the characteristics and behaviour of each pigment in its pure form. Casein paints can be applied in thin layers to watercolour paper, but would require a more rigid support, such as a gesso panel, to be applied thickly, as the comparative inflexibility of the paint layer means that it can be prone to cracking. Subsequent layers of paint should be more diluted to aid adhesion, and impasto effects are not recommended. It is possible to varnish casein paintings using an acrylic or damar varnish to obtain a glossy surface if desired, although this is not a necessary step. Casein can also be used as an ingredient in gesso, and is a suitable binder for fresco secco techniques.

Some pigments may require a wetting agent in order to fully disperse within the binder, in which case alcohol may be used.
