Linseed Oil
The most widely used oil medium in painting — and the same binder used in most commercial oil paints. Amber-coloured and pourable like double cream. Increases gloss, transparency, and flow. Slows drying time slightly compared to paint straight from the tube. Dries to a strong, flexible, durable film — one of the most archivally stable binders in painting history. Important limitation: linseed oil yellows over time, particularly in dark or unlit storage. This yellowing bleaches back when the painting is returned to light, but avoid using linseed for whites, pale blues, and delicate flesh tones.
Properties ▾
Base: Cold-pressed or refined linseed (flaxseed) oil
Colour: Amber
Consistency: Fluid — like double cream
Drying speed: Moderate to slow (slows paint)
Yellowing: Yes — significant in dark conditions
Film strength: Excellent — strongest of all drying oils
Fat-over-lean: Yes — increases oil content of each layer
Techniques ▾
Loosening tube colour
Add a small amount to stiff paint on the palette to increase flow without thinning colour. A little goes a long way — start with a drop.
Glazing: Thin paint with linseed oil to a transparent consistency. Apply over a completely dry layer. Each glaze intensifies the colour beneath without obscuring it.
Fat-over-lean layering: In multi-layer indirect painting, each successive layer should contain slightly more oil than the layer below. Start with solvent-thinned paint (lean) and gradually increase linseed content in upper layers. This prevents cracking as the painting cures.
Traditional glazing medium: Mix linseed oil 1:1 with turpentine or OMS. This is the simplest and most historically used glazing medium — fluid, transparent, and easily controlled.

Linseed oil has been central to European oil painting since the 15th century. The Old Masters worked with it daily. Its yellowing is real but manageable — a well-lit painting rarely shows it. The strength and flexibility of its dried film is why paintings from 500 years ago still exist.
