For modern refining of turpentine, there are basically two ways of doing it: 1) gum spirits of turpentine is distilled from the bark resin only, and 2) wood turpentine is made from ground or chipped pine wood treated with a petroleum-based solvent called naphtha. The naptha draws out the resin from the wood.
Before the 20th century, the process of making what we today call âturpentineâ was much more cumbersome than the process of making other oils such as oil of spike lavender and oil of rosemary. The reason was simple: to extract turpentine from bark, inefficient collection âboxesâ had to be cut into trees.
