Zest It pure unrefined cold pressed Linseed oil enhances the flow of oil paints and reduces the visibilty of brush marks.

Zest-it Linseed oil comes direct from a farm in the UK that produces Flaxseed/Linseed oil for dietary and culinary use. It is cold pressed to extract the oil without the use of heat, solvent or chemicals.

The unrefined oil is filtered to remove any suspended mucilage or particulate and is ideal for use with oil paint or for grinding your own pigments. It is the suspended mucilage and particulate that turns 'brown' over time, not the oil itself, so the extra filtering gives an oil that is less prone to yellowing.

Cold pressed Linseed oil is very useful for those wishing to use less solvents in their work. Only a small amount needs to be added to the oil paint to alter its working properties. Zest-It would consider this a 'fat' medium, so it is not advisable to place a solvent thinned paint layer over it, as this could cause cracking.
