A marble is a small spherical object often made from glass, clay, steel, plastic, or agate. They vary in size, and most commonly are about 13 mm (1⁄2 in) in diameter. These toys can be used for a variety of games called marbles, as well being placed in marble runs or races, or created as a form of art. They are often collected, both for nostalgia and for their aesthetic colors.

Sizes may vary, but usually range from about 0.5 cm to 3.5 cm in diameter.^[1]

In the North of England the objects and the game are called "taws", with larger taws being called "bottle washers" after the use of a marble in Codd-neck bottles, which were often collected for play.

In the early twentieth century, small balls of stone from about 2500 BCE, identified by archaeologists as marbles, were found by excavation near Mohenjo-daro, in a site associated with the Indus Valley civilization.^[2]: 553 In modern India the game is called "kanche". Marbles are often mentioned in Roman literature, as in Ovid's poem "Nux" (which mentions playing the game with walnuts), and there are many examples of marbles from excavations of sites associated with Chaldeans of Mesopotamia and ancient Egypt. They were commonly made of clay, stone or glass. Marbles arrived in Britain, imported from the Low Countries, during the medieval era.^[3]: 19

In 1503, the town council of Nuremberg, Germany, limited the playing of marble games to a meadow outside the town.^{[4][unreliable source?]} The name "marble", used for the little toy balls, comes from this region and era, and refers to such balls being made of marble.^[5] At this point, marbles were made in mills and quarries by polishing small fragments of real stone like marble, agate, alabaster, limestone, and even brass.

It is unknown where marbles were first manufactured.^[6] A German glassblower invented marble scissors, a device for making marbles, in 1846.^[7]: 148 Ceramic marbles entered inexpensive mass production in the 1870s.^{[citation needed]}

The game has become popular throughout the US and other countries.^[8] The first mass-produced toy marbles (clay) made in the US were made in Akron, Ohio, by S. C. Dyke, in the early 1890s. Some of the first US-produced glass marbles were also made in Akron by James Harvey Leighton. In 1903, Martin Frederick Christensen—also of Akron—made the first machine-made glass marbles on his patented machine. His company, M. F. Christensen & Son Co., manufactured millions of toy and industrial glass marbles until they ceased operations in 1917. The next US company to enter the glass marble market was Akro Agate. This company was started by Akronites in 1911, but located in Clarksburg, West Virginia. Today, there is only one American-based toy marble manufacturer: Marble King, in Paden City, West Virginia.^[9][10]

Various games can be played with marbles.

One game popular in the United Kingdom and United States is ring taw (or "ringer"), where a ring is drawn on the ground and a number of small marbles placed within it. Players take turns to flick a larger "taw" marble at these marbles, attempting to knock them out of the ring.^[12]

In kanche (from South Asia),^[a] players prepare for the game by standing behind a line and trying to flick their marble towards a designated hole, with the player who manages to flick their marble closest to the hole getting the chance to go first in the game. The marbles are all then placed in the center of a circle, with each player getting one striking marble and the chance to flick their marble in an attempt to strike the circle-marbles out of the circle. Each marble thus displaced is acquired by the striker, and once all the marbles have been struck out of the circle, the player with the most marbles wins the game.^[13][14]

Similarly, in pili goli (South Asia), the goal of the game is to flick a striking marble in order to knock other marbles laid around the field into holes that have been dug into the ground.^[15][16][b]

The British and World Marbles Championship has been held at Tinsley Green, West Sussex, England, every year since 1932.^[17][18][19] (Marbles has been played in Tinsley Green and the surrounding area for many centuries:^[17][20] TIME magazine traces its origins to 1588.^[21]) Traditionally, the marbles-playing season started on Ash Wednesday and lasted until midday on Good Friday: playing after that was thought to bring bad luck.^[18] More than 20 teams from around the world take part in the championship, each Good Friday; German teams have been successful several times since 2000,^[17][20][22] although local teams from Crawley, Copthorne and other Sussex and Surrey villages often take part as well;^[17][21][23] the first championship in 1932 was won by Ellen Geary, a young girl from London.

• "Knuckle down": the position adopted at the start line at the beginning of a match. The player begins with their knuckle against the ground.
• "Quitsies": allows any opponent to stop the game without consequence. Players can either have "quitsies" (able to quit) or "no quitsies".
• "Keepsies" (or "for keeps"): the player keeps all the marbles they win.
• "Elephant stomps": when called, it allows a player to stomp their marble level with the ground surface, making it very difficult for other players to hit.
• "Bombies": when called, it allows a player to take one or two steps while holding their marble and, while closing one eye, to line up over one of the opponent's marbles and drop the marble trying to hit the marble on the ground.
• "Leaning tops": when called, a shooter leans in on their off hand for leverage over an indentation on any type of surface or obstacle.
• A "taw" or "shooter" is generally a larger marble used to shoot with, and "ducks" are marbles to be shot at.
• Various names refer to the marble's size. Any marble larger than the majority may be termed a boulder, bonker, cosher, goen, masher, plumper, popper, shooter, thumper, smasher, goom, noogie, taw, bumbo, crock, bumboozer, bowler, tonk, tronk, godfather, tom bowler, fourer, giant, dobber, dobbert, hogger, biggie, jumbo or toebreaker. A marble smaller than the majority is a peawee, peewee or mini. A "grandfather" is the largest marble, the size of a billiards ball or tennis ball.
• Various names for different marble types (regional playground talk, Leicester, UK): Marleys (marbles), prit (white marble), Kong (large marble), King Kong (larger than a bosser), steely (metal bearing-ball). Names can be combined: e.g. prit-Kong (large white marble).

There are various types of marbles, and names vary from locality to locality.^[24]

• Aggie – made of agate (aggie is short for agate) or glass resembling agate, with various patterns like in the alley
• Alley or real – made of marble or alabaster (alley is short for alabaster), streaked with wavy or other patterns with exotic names like corkscrew, spiral, snake, ribbon, onyx, swirl, bumblebee, and butterfly

The interior figures are made of white clay or kaolin, and appear a silvery color due to light refraction. A sulphide with a colored-glass sphere, or with a painted figure inside, is also very rare and brings a high price. Like other types of antique marbles, sulphides have been reproduced and faked in large quantities.
• Swirly – a common marble made out of glass with one swirly color
• Shooter – any marble but in a bigger size
• Tiger – clear with orange-yellow stripes
• Baby – white with colors visible on the outside

Art marbles are high-quality collectible marbles arising out of the art glass movement. They are sometimes referred to as contemporary glass marbles to differentiate them from collectible antique marbles, and are spherical works of art glass.

Collectible contemporary marbles are made mostly in the United States by individual artists such as Josh Simpson.

Art marbles are usually around 50 millimetres (2.0 in) in diameter (a size also known as a "toe breaker"), but can vary, depending on the artist and the print.

Marble players often grow to collect marbles after having outgrown the game. Marbles are categorized by many factors including condition, size, type, manufacturer/artisan, age, style, materials, scarcity, and the existence of original packaging (which is further rated in terms of condition). A marble's worth is primarily determined by type, size, condition and eye-appeal, coupled with the law of supply and demand. Ugly, but rare marbles may be valued as much as those of very fine quality. However, this is the exception, rather than the rule, and normally "condition is king" when it comes to marbles. Any surface damage (characterized by missing glass, such as chips or pits) typically cuts book value by 50% or more.

Due to the large market, there are many related side businesses that have sprung up such as numerous books and guides, web sites dedicated to live auctions of marbles only, and collector conventions. Additionally, many glass artisans produce art marbles for the collectors' market only, with some selling for thousands of dollars.^[26]

Marbles are made using many techniques. They can be categorized into two general types: hand-made and machine-made.

Marbles were originally made by hand. Stone or ivory marbles can be fashioned by grinding. Clay, pottery, ceramic, or porcelain marbles can be made by rolling the material into a ball, and then letting dry, or firing, and then can be left natural, painted, or glazed. Clay marbles, also known as crock marbles or commies (common), are made of slightly porous clay, traditionally from local clay or leftover earthenware ("crockery"), rolled into balls, then glazed and fired at low heat, creating an opaque imperfect sphere that is frequently sold as an "old timey" marble. Glass marbles can be fashioned through the production of glass rods which are stacked together to form the desired pattern, cutting the rod into marble-sized pieces using marble scissors, and rounding the still-malleable glass.^[27]

One mechanical technique is dropping globules of molten glass into a groove made by two interlocking parallel screws. As the screws rotate, the marble travels along them, gradually being shaped into a sphere as it cools. Color is added to the main batch glass and to additional glass streams that are combined with the main stream in a variety of ways. For example, in the "cat's-eye" style, colored glass veins are injected into a transparent main stream. Applying more expensive colored glass to the surface of cheaper transparent or white glass is also a common technique.

Currently, the world's largest manufacturer of playing marbles is Vacor de Mexico. Founded in 1934, the company now makes 90 percent of the world's marbles.^[28] Over 12 million are produced daily.
