There shouldn’t be a baseball fan in the world who hasn’t dreamed of catching the ball from a home run or foul line in the stands to keep that trophy as a memento. But few are surprised: What are baseballs made of?
The combination of materials that make up a baseball is a of the most complex of sports because unlike the other balls this one must be hard, it must be able to bounce a little and not contain air inside.
are required four materials for the composition of one of these balls.
Baseball has a circumference of 22.5 cm and weighs 150 grams, it is both the base of the game and a great souvenir for fans but not everyone knows what’s inside.
The center of the baseball is a rubber ball with a circumference of 10 and a half centimeters. That sphere has a little inside round cork core.
In the center they wrap four layers of yarn or yarn. The first is denser and serves to give it volume, then a denser one follows to end up with a thinner one. The last is a very fine cotton thread because it is what makes the surface smoother to be able to apply the last layer. 370 meters of wire are used here.
The exterior is made up of two slabs of Synthetic leather or figure-of-eight leather with 108 perforations, which goes through a process called ‘wetting’, with which we try to soften them so that they can be shaped and guarantee a good duration.
Finally, the seam is made with nylon or red polyester thread with which 216 stitches are made to seal the entire ball.
