The introduction of Walnut Oil as a pigment binder is contemporaneous with the emergence of Linseed Oil. Their drying properties have been appreciated since the Middle Ages, and throughout history there is evidence of both oils being used alongside each other within the same painting. In fact, until the sixteenth century, it is believed that Walnut Oil was the preferred binding medium among Italian artists. It is made from mature walnut kernals, offering a pale colour and brilliant gloss. For this reason, it is sometimes chosen as a binder for light colours, as it provides a stronger paint film than Poppy Oil, and faster drying times. However, a paint film made from Walnut Oil will tend to be brittle, so it is more suited to a rigid support rather than canvas. 

This watercolour paint making set includes a 30ml glass vial of gum Arabic crystals and another of Hampstead Orange, a pigment rich in iron oxide. A pamphlet detailing a a watercolour recipe and an introduction to London pigment is also included. The perfect gift for artists getting into making their own art materials or those interested in handmade British earth colours. The pigment itself has a fine to medium grain size and has been washed, levigated and ground to create a stable high quality artist’s pigment.

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."

Gamsol is an odourless mineral spirit created by the American company Gamblin. They describe it as "the safest solvent that allows oil painters to utilize all traditional painting techniques without compromise."

Please see below for Gamsol's primary applications.

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.

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.
