M Graham Walnut Oil Sampler Set

Interested in trying out this unique oil medium? Then this M Graham Walnut Oil Sampler set is for you. This set includes two bottles of M. Graham Walnut Oil mediums: 2oz Walnut Oil, and 2oz Walnut Alkyd. Walnut oil has a unique refractive index, so colors ground in this fine medium are more jewel-like and bright. Additionally, Walnut oil does not yellow as much as other oils. This is especially important in whites, blues, and yellows.

Walnut oil is a natural oil that does not evaporate or remove essential oils from the artist brushes. The addition of M Graham walnut oil to oil paint will slow drying, enhance flow, and increase sheen. It will dry a bit slower than linseed oil. Based on environmental factors and paint film thickness, about 20% slower.

M. Graham Walnut Alkyd medium thins oil colors, accelerates drying, enhances adhesion between layers and increases surface sheen and flexibility while remaining essentially non-yellowing. M Graham walnut alkyd is non toxic and there are no solvents used in it. It is an alcohol-based resin mixed with walnut oil. This medium is a drying agent, but the most important feature is increased adhesion between the paint film, the painting surface and the paint layers themselves. This makes for a more durable painting.

These mediums are designed to augment the special nature of M Graham oils, but are completely compatible with other artists oils and mediums.

If you want your paint more fluid or creamy, then add a small amount of medium as in 1 – 3 drops per inch of extruded paint and mix it in. You can always add more, but do so in small amounts until you get the desired consistency. There is not an exact measurement or rule, as every artist and technique is different. However, we caution about adding too much as your paint can become too thin and oily.

It is important to realize that the masters did not have petroleum based solvents. As a result, they had to clean their brushes with, in most cases, walnut oil. And you can too! Just wipe excess oil paint off your brush with a rag or paper towel and then dip your brush into a container of walnut oil. Then, using your rag or paper towel, wipe the paint off the brush. Repeat this process until all paint is removed. Be sure to wash your brushes with warm water and a mild soap such as Dawn, Pink Soap, Murphy’s Oil Soap, or brush soap at the end of the day. If you leave any paint in the brush, it will dry and the brush will become unusable.

For oiling out, we recommend using the walnut oil instead of alkyd medium. After the paint has cured (dried), take a soft cloth and apply a very thin layer to the surface, wiping 90-95% off. You want to leave a very thin, even layer.
