resin v. rosin

Resins are clear, yellowish, viscous liquids secreted by plants, especially conifers. Natural resins are primarily hydrocarbons, and are insoluble in water. Synthetic compounds that set into a lacquer-like finish are also called resins. Resins are used in the production of varnish, adhesive, perfume, and incense.

Rosin is a type of solid pine resin obtained by distilling turpentine to remove the oils. Rosin is applied to the bows of stringed instruments, ballet shoes, and gymnasts’ palms to increase friction. Rosin is also used as soldering flux, and is the primary ingredient in mystic smoke.
