Daler Rowney Turpentine 75ml

By its very nature, oil colour is incompatible with water and dissolves only in turpentine, white spirit or low-odour thinners. Artists’ oil colours are made by dispersing pigments in an oil medium to create a smooth, slow-drying paint.
The choice of oil mediums from the wide variety available depends on the surface and the finish required, and the working properties preferred during painting.

Turpentine
Dilutes oil colour to create thin, quick-drying washes in the early stages of painting. Also used to clean brushes.
