This guide examines oil painting mediums made by Natural Pigments. These paint mediums are designed to alter the consistency of oil paint in novel ways, different from the varnishes that were in common use since the nineteenth century and alkyd mediums today. Painting mediums change the handling properties of paint, such as flow out and leveling; increase or decrease tackiness and drag; hasten or retard drying time, increase or decrease gloss; increase transparency, and other physical properties of oil paint...
