Marble may be heated to drive off carbon dioxide, leaving calcium oxide or lime. Probably the most famous white marble comes from Carrara in Italy. Earth movements may shatter the rocks, producing fissures that are afterward filled with veins of calcite; in this way the beautiful brecciated, or veined, marbles are produced.

For example, granite is a very hard rock. Dolomitic stone is any of a variety of stones (such as its namesake, dolomite) which contains calcium and magnesium compounds, which are very good at aiding in crystallization and metamorphism, as well as forming solid bonds.

Bands of calc-silicate rock may alternate with bands of marble or form nodules and patches, sometimes producing interesting decorative effects, but these rocks are particularly difficult to finish because of the great difference in hardness between the silicates and carbonate minerals. A. Volcanic. Glass marbles entered mass production in 1846, with the German invention of marble scissors. Unlike other types of rocks, such as metamorphic rock, granite has formed as a result of magma cooling. Ancient toys resembling marbles were made of smooth stone, clay, or nuts.
