Turpentine is the resinous exudation of various coniferous plants. Turpentine is a valuable solvent, it is clear, limpid and colourless. It evaporates almost completely, leaving no visible residue when exposed in a thin film. Turpentine dissolves all vegetable and mineral oils, but does not dissolve the linoxyn formed by the drying of a paint film, and as such does not disturb previously applied coats of paint making it the ideal solvent for use in paints, though its use declined in preference to cheaper white spirit.
