Refined Safflower Oil Product Information
Product Application
Langridge Refined Safflower Oil may be used for the grinding of oil colours. It may also be added to oil colours and oil mediums at the discretion of the artist.
Refined Safflower Oil is used extensively for grinding pale pigments because of its’ very light colour that will alter minimally the colour of the resulting milled oil paint. It does not has as great a wetting power as cold pressed safflower oil however it’s refinement process makes it less prone to yellowing over time and slightly faster drying. Safflower oil is considered, alongside poppy, to be the most desirable drying oil for making white, blue and other pale coloured oil paints. For more information on the grinding of oil colours.
As a medium, Langridge Cold Pressed Safflower Oil adds a loose, slippery quality when added to oil colours. Safflower oil however, does not dry to as tough a final film as linseed and the use of safflower should be kept to a minimum as a medium to aid fluidity or transparency. Use sparingly, and if wishing to employ glazes or washes Langridge recommends the use of Stand Oil, a virtually non-yellowing oil which dries to a tougher, more resilient film than safflower, as the basis for painting mediums.
Refined Safflower Oil is very slow drying. The paint film will stay open and is easily moved or reworked for up to 72 hours, the surface of the paint film staying wet for up to a week.
This can be problematic in severely slowing down the painting process. Cobalt driers may be introduced to accelerate drying rates, but the potential for increasing the yellowing of the paint film when driers are incorrectly added should be noted.
Langridge Refined Safflower Oil should be considered a slow drying ‘fat’ medium. It should not to be used for underpainting if oil colours with no additional safflower oil is to be applied on top.
Dries to a gloss finish.
Altering the drying rate of existing paints and mediums
Added in relatively small quantities (5% approx. replacement of paint, 10-20% replacement of medium), safflower oil can be utilised to slow down the drying rate of oil paints and mediums.
As noted earlier, safflower oil does not dry to as tough a film as linseed, but if mixed in sufficiently small amounts with linseed or stand oil based mediums, these problems can be obviated.
Thinning
For best results thin with Distilled Gum Turpentine. However, Langridge Low Toxic Solvent Solvent or Solvent 75 may be substituted. Due to the lower solvency action of the latter solvents, an increase in ratio compared to turpentine may be required. Over-thinning with solvents can lead to the partial destruction of the paint film. Langridge recommends a dilution rate of no more than 30%.
Appearance
Langridge Refined Safflower Oil is a clear to light straw colour liquid with characteristic Safflower oil odour.
The colour of the oil will not effect the oil colours with which it is mixed.
Clean Up
Clean brushes with any artists’ solvent (eg Gum Turpentine, Low Toxic Solvent, etc.).
For further washing apply a small quantity of Marseille or other pure olive oil soap and massage the bristles of the brush to release any remaining colour. Wash thoroughly in warm water. Leave to fully dry before using for oil colours.
Drying Times
6-9 days to touch dry.
Full film drying 3-6 months
