Lionseed oil

[D Smyth]

Hi... What is the difference in the properties and the uses of ordinary linseed oil and boiled linseed oil. tx DS

Boiled linseed oil is partially polymerized so that it becomes a "drying oil", meaning that it will cure or harden in the presence of oxygen. Raw linseed is a non-drying oil, and just turns gummy. Casey

Or in much simper terms, Boiled Linseed oil in used in the making of paints and raw linseed oil is used in the treatment of wood.

The unboiled stuff is less common (and more difficult to find in stores). It is very good for applying to outdoor projects that you don't come in contact with, such as fences, trellises, retaining walls, etc. The unboiled oil lasts much longer than the boiled.
