A bowling ball having hard and inflexible flake materials arranged in a substantially interlocking relationship and located at or just below the outer surface of the bowling ball to form a substantially continuous interlocking armored layer about the bowling ball which causes it to have an appreciably greater resistance to penetration by a Shore D Hardness test needle than a bowling ball of identical composition but without the flake type materials. Sufficient resistance to penetration by the Shore D Hardness test needle gives a durometer hardness of at least seventy-two. The flake materials have an average size of from -100 mesh to 40/100 mesh and comprise between one to ten percent by volume of the bowling ball's outer shell admixture. Further, the outer surface of the bowling ball may be pitted by including dissolvable particles and collapsible hollow particles in the outer shell and given microscopic protrusions due the addition of soft resilient particles and hard inflexible particles in the outer shell of the bowling ball all of which are sufficiently small to allow the ball to roll upon the bowling lane without appreciable discontinuities in forward motion and without appreciable damage to said bowling lane. Further, the angular momentum and hooking action of the bowling ball is affected by adding particles with a density at least twenty percent greater than the density of the substrate in the outer shell or by placing particles capable of reducing the weight by volume of the outer shell by at least five percent.

A bowling ball having an inner core and at least one thermosetting resin shell which contains sufficient lightweight particles, such as unicellular borsilicate glass spheres, having a diameter within the range of from about 10 to 100 microns and evenly dispersed therethrough to reduce the weight by volume of the shell by at least five percent below that of a similar volume of said thermosetting resin without said lightweight particles. The lightweight particles appearing on the outer surface of the shell will create a finely pitted texture. The manufacturing method comprises substantially uniformly dispersing lightweight unicellular particles in a thermosetting resin mass and molding the mass about an inner core while maintaining the particles substantially uniformly dispersed in the mass until the resin gels sufficiently to prevent substantial movement of said particles, minimizing air inclusions through the use of surfactants, proper agitation and vacuum, use of resins and conditions which promote rapid gelation, and use of such lightweight particles as will sufficiently lower the weight by volume of the resin and also maintain the integrity of the resultant bowling ball.

A bowling ball having a thin viscous film deposited upon its surface from within the ball for increasing the coefficient of friction between the ball and the bowling lane. The film comprises a saturated plasticizer incorporated into the ball at the time of manufacture that slowly exudes from the outer shell over an extended period. The method comprises preparing a resin blend capable of being cured into a tough, durable material and mixing the resin blend with a plasticizer which is miscible with the liquid phase resin blend, but incompatible with the solid phase. Catalysts are admixed and heat is applied to the mixture to cure the resin blend into a tough and durable outer shell.
