The majority of regular size marbles weigh less than 0.16 ounces. However, the weight of a glass marble varies depending on the size of the marble and the glass used to make the marble.
Marbles are sold in a variety of sizes and designs. The typical marble used to play games measures 9/16-inch. Marbles larger than this are often used for decorating purposes. Marbles date back to the Romans where they were mentioned in different pieces of literature. They did not start becoming manufactured commercially until the 1800s. In the early 1900s, the first glass marbles were produced in the United States. James Harvey Leighton received a patent in 1903 and began making the marbles on his machine. Martin Frederick Christensen also began producing the marbles and did so until the year 1917.
