A pale viscous oil that can be mixed with Turpentine or White (Mineral) Spirit to improve the flow and levelling of oil colour. Retards drying but imparts a tough, elastic finish. Use in conjunction with Turpentine or Artists' White Spirit to improve colour flow. It is well suited for glazing and for fine detail and is resistant to yellowing while increasing the durability of the film. It slows drying and is the best oil to choose as an additive medium.
