Modern-day golf balls are classified based on the number of layers of rubber materials in their core, such as 2-piece, 3-piece, and 4-piece. The outer covers are usually made of either urethane or surlyn. While some might wonder about the mysterious contents of a golf ball, it's safe to say that they are not filled with rubber bands or water!
The History of the Golf Ball
The evolution of golf ball composition has been quite intriguing. Early humble golf ball versions were simple wooden spheres, later replaced by featherie balls in the 15th century. These were leather balls filled with feathers and painted white, but they had their limitations due to water absorption and irregular shape. In the 19th century, the gutta percha ball, made from natural latex, gained popularity, being more affordable and uniform in shape.
A significant breakthrough came with the creation of Haskell balls by winding rubber strands around a solid core and coating them with gutta percha. These balls featured dimples on their surface for improved flight characteristics. Over time, advancements allowed for the elimination of layered rubber cores, resulting in the widely used 2-piece balls today.
Presently, the modern golf ball is categorized by the number of cores they have, and their composition is carefully engineered for different performance advantages. For example, Titleist Pro V1's are 3-piece balls, but their premium materials set them apart. Throughout history, golf ball design has aimed to increase distance and provide better control around the green. This won't stop golfers from blaming the ball or talking to it out on the golf course.
