Williamsburg Cold Pressed Linseed Oil 473 ml — Artist oil medium for improved flow & gloss

Williamsburg Cold Pressed Linseed Oil is a minimally processed, pressure-extracted linseed oil sold in a 16 fl oz bottle, designed to modify oil paint handling and finish without heavy refining.

Made in the USA by an employee-owned company with over four decades of paintmaking experience, this cold pressed linseed oil is produced through mechanical pressure rather than alkali refining. The result is an oil that preserves more of the seed’s natural character, intended for artists who want a historically authentic medium to alter paint viscosity, gloss, and drying behavior in controlled studio work.

How does cold pressed linseed oil change paint handling?

Cold pressed linseed oil increases paint fluidity and transparency while enhancing gloss, so you can achieve smoother brushwork and subtler glazing without adding resin. It’s less processed, which can preserve naturally occurring components that influence flow and leveling.

• Improves brushability and flow for longer wet edges
• Increases gloss and transparency for glazes
• Requires only small additions to adjust consistency
• Works with oil colours, alkyds, and traditional mediums

Is cold pressed linseed oil the same as refined linseed oil?

No — cold pressed oil is mechanically extracted and undergoes less chemical processing than alkali-refined versions. That means it retains more of the seed’s natural constituents and a character closer to historical artist oils, although properties may vary slightly batch to batch.

• Extracted by pressure rather than chemical refining
• Less standardized than highly refined oils
• Closer to traditional studio recipes used by historic painters
• May show subtle natural aroma compared with refined oils

How should I use and store Williamsburg Cold Pressed Linseed Oil?

Use sparingly—mix a few drops into paint on the palette or apply thinly between layers to adjust flow and translucency. Store the sealed 16 fl oz bottle in a cool, dark place away from heat, and keep the cap tightly closed to slow oxidation.

• Add in small amounts to avoid overly slow drying
• Apply thin films rather than thick layers for safety and cure
• Keep container sealed and stored upright, away from direct sunlight
• If unused for long periods, check for cloudiness or odour changes
