Standard distillation for use with artists oil colours. Evaporates slowly and evenly over 8-12 hour period. Tends to leave paint films even with regular glossing ( excessive dilution of oil colour with any solvent will tend towards a slight matting of the dried paint film). Keep in air tight closed tin avoid prolonged exposure to air or light (can lead to thickening/discoloration of turpentine). Use in environments with adequate ventilation.
