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.
1 More than a half-dozen additional Pinus species have been used in the production of turpentine. 4 The oleoresin is sometimes referred to as âgum turpentineâ while turpentine or its oil (also known as spirits of turpentine) are terms for the essential oil. Following steam distillation, gum turpentine yields turpentine oil and a resin called colophony (also known as rosin).
