Painting Mediums & Additives
Oils & Mediums
When mixed with oil paint, Michael Harding’s linseed oil increases the gloss and transparency of the paint, thins the paint for easier flow, and reduces visible brush marks. It also slows the drying time of the paint. However, using too much can cause yellowing due to the natural color of the oil and can lead to defects like wrinkling if layers are applied too thickly.

Refined Safflower Oil is bright, clean, and one of the highest in colour for oil, a favourite for my Titanium White No. 1.
Safflower oil is a pale, slow-drying oil that can be used to brighten and thin oil paints.
As it is a paler yellow than linseed oil, paler pigments (whites and pale blues especially) maintain their brightness when mixed with safflower oil.

My Oleo Impasto Medium is a gel made from fumed silica and linseed oil, the combination of which imparts great luminosity, particularly with transparent colours. Use this in varying amounts with a brush or knife to achieve extra body.

Gamsol is an excellent solvent for thinning Gamblin mediums and for general painting. It evaporates 100% and leaves no residue in paint layers. Gamsol is less toxic than other brands of OMS (Odorless Mineral Spirits), mineral spirits, or turpentine because the harmful aromatic solvent component has been removed. It's also useful for studio and brush cleanup.
