Cobalt Green is a synthetic pigment that consists of compounds of cobalt and zinc oxides. It is sometimes referred to as Rinman's Green, after the Swedish chemist who discovered it in the late-18th century. It is a permanent, opaque colour, with a weak tinting strength. It dries quite quickly in oil, requiring a high oil content and  forming a hard, fairly fleixible paint film. Cobalt Green is available in light and dark shades; the colour is determined by the amount of zinc oxide present.

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

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.

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.

Yellow Ochre is a natural earth pigment that has been in use since prehistoric times. It is derived from iron-rich clay deposits that are present all over the world; our Yellow Ochre comes from the hilly regions around Verona, Italy. As a pigment, it is semi-opaque, extremely lightfast, and stable in all media. It has a medium to slow drying rate in oil, creating a tough, flexible paint film. Yellow Ochre is similar in composition to Raw Sienna, 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 compositional difference creates a paler, more opaque Yellow Ochre, and a darker, more transparent Raw Sienna.

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
