A glass slab with wooden cradle for the grinding of pigments.

The friction created between the sand-blasted surfaces of the glass slab and muller facilitates the thorough mixing of pigment and medium, creating a consistent and strong paint body. This slab can be used to manufacture many types of paint including watercolours, egg tempera and oils.

Mulling is of particular importance when making oil paint; simply mixing pigment and oil together using a palette knife will result in an unstable substance with poor plasticity, which contains a large amount of excess oil and unevenly distributed pigment particles. Thorough mulling in a figure-of-eight motion will enable the pigment to be fully combined into the binder, strengthening the resultant paint film.

PLEASE NOTE: The separate glass slabs are in stock but it is a call to order item due to the fact that we cannot guarantee its safe delivery, however well we package it. Please ring us to discuss your delivery options. In combination with the glass frame, delivery is more secure but we still cannot guarantee a delivery without breakage.

Venice Trupentine is a thick, resinous liquid extracted from the Larix decidua, a larch tree native to Austria. It can impart luminosity, brilliance and gloss when used in mediums and varnishes, and as such it was highly valued during the Golden Age of painting in Venice. It is a slow-drying balsam, which can be diluted with turpentine or placed in a bath of warm water to aid flow.

Phthalo (Mona) Blue is a synthetic organic pigment, Copper Phthalocyanine, that has been in use since the 1930s. It has an extremely high tinting strength and is a staining colour, so cannot successfully be lifted in watercolour. It requires a wetting agent to fully disperse into a medium, and, when used at full strength, a copper sheen is visible in dried paint film. It is transparent, very lightfast, and has a medium-to-slow drying rate in oil.

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

PB35

Cerulean Blue is an artificial mineral pigment that is prepared by heating a mixture of Cobalt Chloride and Potassium Stannate. It was first synthesised in the early nineteenth century, becoming more widely used from 1870, when Rowney introduced Coeruleum Blue into their range. It produces a very bright, clear, and unusually opaque blue, hence its name, which is derived from the Latin for "sky-blue", or perhaps "heaven-blue". It has a very low tinting strength meaning that, although it is stable in all media, some artists may choose to bind it in poppy rather than linseed oil, so that the colour isn't affected by the colour of the binder. It creates a fairly flexible paint film, and is a fast-to-medium drying pigment.

They have an even matt finish which recalls primitive Italian fresco painting. This makes Flashe the ideal medium for all artworks to be photographed. Also popular for illustration, graphics, comics, model making, fresco and interior mural decoration. Learn More

This ink is made to the recipe that Jane Austen used to draft her novels. Austen's maid took this formula from Martha Lloyd's book, ‘The House Keeper’. She used good-quality English oak galls, but poorer quality beer than Isaac Newton, and added a little sugar. Her recipe is less stable and turns ‘antique brown’ over a long period of time, while Sir Isaac Newton's remains black. Initially a medium blue-grey, it darkens to a rich matte back, slightly warmer in tone than our regular Oak Gall Ink. It is made in small batches and blended to give the required consistency and strength, and is fully waterproof in 5-7 days. Permanent and lightfast, it has been steeped for several weeks and left to ‘mature’ for several more in the bottle. When used on animal skins such as vellum, the acids in the Oak Gall Ink react with collagen, effectively ‘etching’ itself into the surface, hence its permanence.

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.

Formulated to the exact recipe used by Isaac Newton, this ink is completely permanant, as his surving writings attest. Although composed of very similar ingredients to our Jane Austen Ink, we consider Newton's recipe to be superior, as Austen's has browned slightly over time. Initially a medium blue-grey, it darkens to a rich, matte back, which is slightly warmer in tone than our regular Oak Gall Ink. It is made in small batches and blended to give the required consistency and strength, and is fully waterproof in 5-7 days. Permanent and lightfast, it has been steeped for several weeks and left to ‘mature’ for several more in the bottle. When used on animal skins such as vellum, the acids in the Oak Gall Ink react with collagen, effectively ‘etching’ itself into the surface, hence its permanence.

PR233

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.

E C Lyons rockers are known world-wide as the finest mezzotint rockers available. They measure 17.75 cm (7 inches) at their total length, including the stained birch handles, and are made with the highest quality high-carbon tool-steel. The gauge (screen) sizes are available in 45 (coarse), 65 (medium), 85 (medium-fine), and 100 (fine) lines per inch. By working the rocker with a rocking motion over a copper or zinc plate evenly in a cross-hatched fashion, one creates burrs that will trap the ink to produce characteristically rich and velvety blacks, which can selectively be burnished away to produce delicate light areas and soft shading.

Mars Violet is an artificial mineral pigment. Its pigment code, PR101, refers to a wide spectrum of synthetic iron oxide pigments including yellows, oranges, reds, violet-browns and green-browns, which replace many natural earth colours, to provide pigments without impurities and with great opacity. It has a good tinting strength, is lightfast and stable in all media, and has a medium drying time in oil. Although it is similar to Caput Mortuum and Indian Red, it is less transparent than the former and warmer than the latter.

Vine Black is derived from charred vines, forming an organic pigment of pure carbon. It has been in use since antiquity, providing a cold black with bluish undertones, which creates a blue-grey when mixed with white. It is a very lightfast, slow-drying colour with a medium tinting strength. It requires a wetting agent to disperse properly, and is not suitable for use in fresco, mortar or cement, as the water-soluble impurities within the pigment can create efflorescence.

Oak Gall Ink was originally used in monasteries and by the Crown in medieval Britain. Doomsday Ink initially lays down as a medium blue-grey, darkening to a rich, matte black, slightly warmer in tone than our other Oak Gall Inks. When diluted, beautiful warm red undertones are revealed due to the presence of wine within the mixture.

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.
