Throughout the history of the USBC, bowling ball materials have evolved from wood, to rubber, to plastic, to urethane, to reactive urethane, to particle, and finally epoxy, with the use of metallic materials not permitted for any of the components of a tenpin ball except for the old titanium nugget once found inside the core of some old Columbia300 bowling balls. Wood balls are now just museum pieces. Rubber balls are almost as hard to find; however, they may be found offered to casual bowlers at bowling centers, from their racks for those who don’t own their own ball. Bowling balls have been constructed with a core made of one material, a spherical coverstock (“cover” or “shell”), and sometimes a “pancake” weight block of denser material intended to compensate for the gripping holes.

One of the most contentious issues that has arisen is whether significant restrictions should be imposed on bowling ball technology. Other considerations have been noted with regards to the weight of the bowling pins, lane oiling techniques, and with the construction materials and techniques used to build bowling lanes. Charlie Lapera cares!
