Made from organic walnut husks collected in Cambridgeshire, this deep brown walnut ink is made to an 18th-century formula. Small batches of the ink are blended to give the required consistency and strength. It has good permanence, but will eventually fade if left in direct sunlight for sustained periods of time, and is not wholly waterproof, but has some staying power, especially on sized watercolour papers. As with all handmade products derived from natural ingredients, there may be slight variations in the colour and consistency as a result of seasonal changes.

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

This unique colour is an intense orange oxide that is made from the decay of Victorian pipes mixing with the chalk bed of the infilled docks at Rotherhithe, in south east London. Rotherhithe has a long history as a port, with many shipyards from Elizabethan times until the early 20th century and with working docks until the 1970s, when they began to be infilled due to a decline in imports to Central London. With a fine particle size and transparent quality this pigment would be great for glazing techniques.

Shellac is a natural resin that is deposited by the female lac insect on the branches of trees in India and Thailand. It is soluble with alcohol, but not with mineral spirits or turpentine. It forms a tough yet flexible film, with many applications. It is suitable as a top coat for gilding when applied thinly, a sealant for porous surfaces, an isolating layer for tempera paintings, a base for pigmented inks, a protective layer for collograph plates, and a warm varnish for wooden floors and furniture. As it is prone to darkening with age, it is not recommended as a varnish for oils, and its solubility can reduce over time. There are various grades of shellac. When mixed with alcohol, it may initially form a cloudy mixture, due to traces of wax in the shellac, but this should become clear once it has dried. The highest grades of shellac are Clear Dewaxed Shellac, which has been de-coloured using the carbon filtering method, Lemon Shellac, and Orange Shellac, which are pale in colour. Button Shellac is less refined and therefore produces a reddish varnish. It was, in fact, widely used as a red dye before synthetic dyes became available. Learn More

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

Ultramarine Blue Limewash 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. Most Ultramarine colours It react to alkali and are therefore unsuitable for use in lime-fresco; Limeproof Ultramarine Blue remedies this problem. 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.

Parchment Clippings, usually waste goatskin vellum, were utilised throughout the Middle Ages to make an animal hide glue. This continued to be commonly used as a sizing for canvas before rabbit skin glue came to prominence in the nineteenth century. Parchment glue is comparable to isinglass glue, as it also produces a very pale, almost transparent glue with a degree of flexibility. Our parchment clippings are a mixture of vellum scraps, and may include goatskin, calfskin and sheepskin. Cennino Cennini gives a recipe for gesso using parchment in his treatise about painting; please see below for our recipe. 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.

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.
