Product Description
Non-yellowing oil for use in all oil mediums.
Thick and honey-like oil, gives enamel-like qualities to paint.
Should be diluted with solvent.
Dries to a tough flexible film.
Stand oil is manufactured by heating Linseed Oil to approximately 300ºC (570°F) in the absence of oxygen. The Linseed Oil polymerises to create Stand Oil.
Product Code: 003

Safety Data Sheet
Product Application
Langridge Stand Oil is diluted with Distilled Gum Turpentine or another appropriate artists’ solvent to produce Oil Mediums.
A unique quality of Stand Oil compared to all other natural artists’ drying oils is it is virtually non-yellowing. The process of polymerisation, however, makes Stand Oil thick and honey-like which cannot be used without the addition of artists’ solvent.
It is not suitable for milling oil colours due to its viscosity and low pH. Stand Oil has a pH of approximately 6.5. Oil colours are best milled in drying oils with a higher acid level, such as Cold Pressed Linseed Oil.
For use of alternative solvents see ‘Working Properties -Thinning’.
After 20-30 minutes of applying Stand Oil based mediums the surface will set-up to a tack that grabs any succeeding brush strokes. The wet, but tacky, paint surface can be readily painted into. This allows for a wet-in-wet technique with very controlled manipulation of paint including soft blending.
Stand Oil has pronounced levelling qualities. If a medium made with over 50% Stand Oil is added to oil colours the resulting paint film will exhibit an enamel finish with little or no physically raised brush marks.
Because Stand Oil cannot be used without dilution, the proportion of oil to solvent determines whether it is a ‘fat’ or ‘lean’ medium. As a general rule it is considered a slow drying ‘fat’ oil and care should be used when using as an ‘underpainting medium’.
Mediums made with Stand Oil as their primary oil dry to a tough flexible film with a gloss finish.
Additional Product Information
For the prevention of sinking-in of paint
If a support for painting (e.g. canvas) is poorly primed, oil colours will ‘sink-in’ to the surface and exhibit a dull and lifeless colour reflection. The oil from the paint is absorbed into the support, leaving the pigment underbound and the surface liable to crack or dust/flake off. In this case ‘oiling-out’ can rectify the paint film.
To even out the final reflective quality of the painting
Due to differences in the gloss or matte sheen of individual paints a finished picture generally has a range of reflective finishes within it. If these are very pronounced, a picture varnish cannot even these differences out completely. The application of Langridge Isolating Medium will help to even out these finishes prior to applying a final Picture Varnish (See..). This process is not providing a removable artists’ varnish, so the application of Retouch Varnish is still recommended. After 3-6 months a final Picture Varnish of the desired matte or gloss quality can be applied.
Working Properties
Thinning
For best results thin with Distilled Gum Turpentine. However, Artists’ White Spirit or Langridge Low Toxic Solvent may be substituted. The use of the latter solvents (petroleum distillates) will tend to reduce the fatness of stroke and the oil film will dry with less richness due to the partial destruction of the paint film.
Appearance
Langridge Stand Oil is a honey-thick, pale yellow colour liquid with a characteristic Linseed Oil odour. The colour of the oil will not affect 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 Langridge Safe-Clean-Up or 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 brushes to fully dry before using for oil colours.
Drying Times
7-14 days to touch dry. Full film drying 3-6 months
