Rick Browne Posted February 19, 2002 Share Posted February 19, 2002 Rosin is distilled resin extracted from pine trees. Violinist use it to rosin up their bows and surely you have seen Major League pitchers pick up a little white bag they keep behind the mound and dust their pitching hand. that is rosin too. Of course, there are many other uses for rosin, but these two examples come to mind Quote Link to comment Share on other sites More sharing options...
