Rosin

Rosin, resin derived from certain pine trees from North America and Europe. A distilling process makes the resin collected from live trees usable in the manufacture of various products, from paints and paper sizing to adhesives and inks. String bows and dance shoes are treated with dried rosin to prevent slipping. Rosins range in color from black to deep red amber, and yellow. The cluster and scotch pines of Europe and the longleaf and loblolly pines of the United States produce most resins for rosin. Three main types of rosin include gum, wood, and sulfa.
