Pine tar is a sticky substance derived from the carbonization of pine wood, primarily from the Pinus species. It is produced through a process called destructive distillation, where wood is heated in the absence of oxygen. This results in a thick, black liquid that has been used for centuries in various applications, including shipbuilding and roofing. In sports, particularly baseball, pine tar is commonly used by players to improve their grip on bats. It helps prevent slipping during swings, enhancing performance. However, its use is regulated, as excessive application can lead to disputes over the legality of a player's equipment.
