This 250 ml medium is non-polluting, it will allow you to improve the consistency of your paste as well as your impasto effects. An essential product for working in the cool. This medium also improves the drying time and brings a touch of shine to your works. Unlike conventional mediums, 'Green for Oil' is a range of mediums and thinner for oil painting that does not contain mineral spirits or turpentine which may bother some users. These discomforts can go as far as irritations and allergies. They have been replaced by mixtures of fatty acids and esters of plant origin. The resins and oils used in the “Green For Oil” range are the same as for the standard additives (ketone resin for the medium, safflower oil for the gel medium). It is the solvents used to implement them that are non-toxic and which make the range non-toxic. The smell is pleasant a bit oily. The liquid medium will allow you to adjust the viscosity of the paste, play with its transparency, and make it shiny on a regular basis.
