What a Baseball is Made Of

A cork nucleus is encased in two thin rubber layers. This is machine-wound with 121 yards of four-ply blue-gray wool yarn, 45 yards of three-ply white wool yarn, 53 more yards of three-ply wool yarn--this time blue-gray in color to denote the stage of manufacture, according to Rawlings--and 150 yards of fine white polyester-cotton blend yarn. This "center" is coated with rubber cement before the cover is put on.

The cover--two pieces of elongated figure-eight-shaped white cowhide--is dampened to permit stretching and hand-stitched together with exactly 216 raised stitches, using 88 inches of red cotton thread. The last step in the process is rolling the balls for 15 seconds while still slightly damp so the seams are even and reasonably flat.

The discussion behind this answer:

• A baseball is made up of 4 main layers. At the center of the ball is a rubber core. Around the core is a layer of cork. Then twine is wrapped around the core. Over the twine is stitched a layer of leather that makes up the cover of the ball.

• Baseball is made up of a rubber core and cork which is the size of a quater. Than the ball is wound with yarn to how thick the ball is in circumference. A white dometic hide is used to cover it and red waxed stiching stiches it together.

• A baseball is made of a rubber core, yarn to give it its thickness, and then a tightly rapped layer of string so that yarn under it doesn't make the ball lumpy or soft, and then the leather cover stitched together with waxed red string.

• A baseball is made of yarn wound around a core of rubber and cork. The covering of the baseball is made of two strips of cowhide sewn together. An official baseball must have a circumference between 22.9 and 23.5 cm and weigh between 5 and 5 1/4 ounces (142 and 149 grams).

• Today, instructions to the manufacturer call for the cork nucleus of prescribed weight (0.5 oz) and diameter (2.86 to 2.94 inches) to be encased in two thin rubber layers--one black, one red--weighing a total of 7/8 oz. The "pill," as it's called, is machine-wound under high, consistent tension with 121 yards of four-ply blue-gray wool yarn, 45 yards of three-ply white wool yarn, 53 more yards of three-ply wool yarn--this time blue-gray in color to denote the stage of manufacture, according to Rawlings--and 150 yards of fine white polyester-cotton blend yarn. This "center" is coated with rubber cement before the cover is put on. The cover--two pieces of elongated figure-eight-shaped white cowhide--is dampened to permit stretching and hand-stitched together with exactly 216 raised stitches, using 88 inches of red cotton thread.

• first a layer of cork, then a layer of rubber, them yarn, then cowhide with 108 double stiches.

• on the outside is a layer of leather with lining, then there is rubber string then dark grey yarn, then white yarn, then lite gray yarn, than a layer of cork, then inside the cork is some rubber

• I heard that baseballs had wool yarn inside, so I opened one up to see if it was worth trying to knit with. I probably should have read the outside of the ball before I tried that. It says "solid cork and rubber", and that's all that I've found inside. No yarn. It's a Rawlings Official League ball.

• A baseball is made up of a rubber core, twine, cow hide, leather, string, yarn, and a cork! These materials are sewn together with rope or yarn. A baseball is also smaller than a softball therefore goes farther when hit, thrown, pitched, or rolled. I love baseball and softball. I play select softball for the Texas Blades! too!

• its made of a small ball of string and it keeps growing then they stitch it...

it is just basically made of 4 layers, a rubber core, cork, twine, and then stiched leather in that order from the core to the surface
