spirit of turpentine
Học thuậtThân thiện
Definition
Noun: * A volatile, flammable liquid: Specifically, a clear, colorless liquid obtained through the distillation of crude turpentine (the oleoresin from pine trees). It is primarily composed of pinene and other terpenes. Its main traditional uses are as a solvent for thinning oil-based paints and varnishes, and as a medicinal substance, though its medicinal use is now largely historical.
Usage Examples
- Noun:
- The artist thinned the oil paint with spirit of turpentine to achieve a smoother consistency.
- In older pharmacopeias, spirit of turpentine was listed as a topical rubefacient.
- Always ensure proper ventilation when using spirit of turpentine due to its strong odor and flammability.
Advanced Usage
- The term "spirit of" in historical and technical contexts often denotes a volatile substance or essential oil obtained by distillation (e.g., for ethanol). Therefore, explicitly refers to the distilled, volatile fraction, distinguishing it from the raw, viscous oleoresin (crude turpentine) or the solid rosin left after distillation.
Variants and Related Words
- Turpentine (noun): In modern common usage, "turpentine" is often used synonymously with , referring to the distilled solvent. However, technically, "turpentine" can also refer more broadly to the oleoresin itself.

- Wood turpentine (noun): Turpentine obtained by distilling pine wood, as opposed to the oleoresin.
