Early glass marbles were handmade - predominantly in Germany - from the 1860s, then machine made from the 1920s. Marbles games with the aim of knocking an opponent's marble out of a ring were a playground favourite.
However, the late 20th century saw a boom in 'art glass' marbles that were not intended as playthings. These were made by independent studio glass artists. Many explore the reflective, refractive or magnifying properties of optical glass.

Value is dependent on technique, size and maker. Notable artists include Paul Stankard, Jessie Taj and Daniel Benway.
'End of the day' glass was made by glassworkers in their own time at the end of the day.
