Stand Oil Allows you to significantly attenuate or smooth thin brush strokes. Linseed oil polymerised in the absence of air. Full bodied, very bright, clear, honey-like viscosity medium made by heating pure linseed. Improves transparency, fluidity and smoothes brushstrokes. Can be used straight but, due to high viscosity, it is preferable to thin with spirits. Excellent medium for glazing and detail work. Reduces possible appearance of cracking. Slows drying. Slightly yellowing. Favors gloss.
