Balsam canada, Natural

Canada balsam, also called Canada turpentine or balsam of fir, is a turpentine made from the resin of the balsam fir tree (Abies balsamea) of boreal North America. The resin, dissolved in essential oils, is a viscous, sticky, colourless or yellowish liquid that turns to a transparent yellowish mass when the essential oils have been allowed to evaporate. Canada balsam is amorphous when dried. Since it does not crystallize with age, its optical properties do not deteriorate.However, it has poor thermal and solvent resistance
