The gum spirits of turpentine and pine gum rosin are derived from slash pine trees (pinus elliottii) growing in south Georgia, USA, using sustainable forest practices. The raw pine gum is harvested and then fire distilled using basically the same methods used for hundreds of years. Finally, they are bottled, labeled, packaged.This turpentine is not to be confused with "rectified turpentine," which is a by-product of the pulp and paper industry and contains sulfates and other impurities. This turpentine is 100% pure and organic.
