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.
However, during the industrial era, the waxy white transparent crystalline substance, consisting of formula C10H16O, synthesised through the bark of the tree, the leaves go through a distillation process via turpentine oil. The resultant camphor chunks/ oil are then used commercially and otherwise.
