About Rosin History: Extraction: Natural resin was and still is obtained from pine trees during fall and turpentine oil is the product which is gained through its distillation. Pieces of natural resin are heated up in a boiler in order to evaporate water from it while at the same time impure components within the now liquefied resin slowly sink towards the bottom of the boiler. As a last step, the pure liquid resin is skimmed off and then cooled down. Origin and Characteristics: You can recognize the origin of the resin by its color. French and North American pure resin has a light yellow color while German pure resin is rather brown. Pure natural resin is transparent, can be easily pulverized and dissolves in alcohol and essential oils. In a successive stage, the pure resin is heated up again while oil and other materials are added. This liquid will then be poured into a mold to form the cake of rosin that musicians are using for their bow hair. Each manufacturer has his very own specific procedure to make rosin which he protects as a strict secret. As a consequence, all rosins today differ in quality and impact the bowing technique and the sound color of an instrument immensely. For the musician it is thus important to carefully choose a rosin which helps him to have the most ideal grip of the bow while playing the strings. Which Rosin should I use?
