Lefranc Bourgeois are a paint manufacturer with a long history of supplying to artists since their beginnings in 1720.

From their website: The Harlem Duroziez drying medium increases the brilliance and transparency of glazes. It enables the build-up of layers over the course of half a day thanks to the rapid drying effect of thin layers. It is completely dry within three days.

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

Schmincke Medium W is an odourless, jelly-like ("lean") medium for mixing oil colours with water instead of organic solvents such as turpentine or turpentine substitute. It increases gloss and transparency, reduces viscosity and harmonizes the drying process.

Dosage: 50%

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

Safflower Oil is light-coloured, making it suitable for grinding pale pigments. It is still sometimes used as a binder for commercially available paints, although due to its very slow drying time it is best reserved for the final layers of a painting. Compared to Linseed oil, Safflower Oil will give a matte finish.

Gamblin Solvent-Free Gel is manufactured by the American company Gamblin. They write:

"Gamblin Solvent-Free Gel is the only solvent-free painting medium that supports a broad range of painting techniques with minimal compromise. Solvent-Free Gel gives colours more flow and transparency, yet holds the shape of your brushmark. Solvent-Free Gel has a moderately fast drying rate and increases gloss. Made from safflower oil and alkyd resin, Gamblin Solvent-Free Gel is non-toxic and contains no Gamsol or petroleum distillates. In comparison to other solvent-free mediums, Gamblin Solvent-Free Gel supports the broadest range of painting techniques with the least compromise across color, dry time, texture and mark-making. To ensure proper drying of paint layers, Solvent-Free Gel should be used in moderation with oil colors. No more than 25% by volume. To avoid wrinkling, apply mixtures of Solvent-Free Gel and oil colors thinly. To paint solvent-free, we recommend Gamblin Safflower Oil for cleaning brushes while you are working. After your painting session, brushes can be further cleaned using Gamsol and/or soap and water."
