### substance:

Marble
* Most marble is susceptible to damage from citric acid and alcohol
  - marbles are in the same color family but different degrees and intensities
* Some marbles have a fine, crystalline texture, large breccia or small fossils.
* actually metamorphoses to limestone from a major change.
* are a type of toy
  - round and smooth, having no jagged edges
* beautiful, porous stone that requires special care.
* causes games.
* coarse, crystalline metamorphic rock composed almost entirely of calcite or dolomite.
* come in many different sizes.
* commonly appears in curbs and sidewalks, as well as in building details.
* crystalline sort of stone.
* form of limestone, or an alkali
* has many color variances due to the impurities present at formation
  - different sizes of crystals
  - the same advantages and disadvantages as other carbonate rocks
* is Taiwan's most important mineral
  - actually a limestone that can be polished
* is an attractive and easily worked rock that has long been used for monuments and sculptures
  - example of a sedimentary rock that has been changed into a metamorphic rock
  - another example of a metamorphic rock
  - balls
  - bands
  - basically the same type of rock as crystalline limestone
  - considered a carbonate rock
  - dense , with a good range of colors
* is found in many places
  - under the segmentation rock
* is located in games
  - jars
  - pouchs
  - stores
  - metamorphized from heat or pressure
  - metamorphosed limestone
* is mined exclusively from limestones and dolostones of Paleozoic age in north Arkansas
  - in Georgia
  - one of the best materials for building a loudspeaker
  - problematic because it is soft and slippery
  - quarried, and anthracite coal and ar- gentiferous lead are mined
  - rounds
  - significantly softer than granite and therefore subject to greater wear and weathering
  - simply limestone that has been subjected to great pressure and heat
  - software
  - spheres
* is the dominant form of stone as several states' contributions meld together in perfect form
  - most common stone for furniture
  - result of an unusual natural phenomenon
  - standard of luxury
* is used as a building stone and as ornamental rock, such as for carving statues
  - dimension stone and in paper and plastic
* is used for decoration of about half the area of walls of Moscow Metro
  - roll
  - sculptures, and coal is used for fuel and energy like light
  - shoots
* is, like slate, relatively soft and quite easy to carve.
* metamorphic limestone or dolostone
  - rock composed of calcite like limestone and travertine
* metamorphic rock formed by the re-crystallization of limestone
* metamorphic rock that forms when limestone is subjected to heat and pressure
  - is formed from the sedimentary rock limestone
  - with large crystals
* natural product
  - stone, a porous product when compared to glazed ceramic tiles
* porous and soft substance that can be damaged by water and air pollution.
* represent leaves, grass clippings, or hazardous wastes.
* softer stone, and tends to wear more easily, where as granite is much harder.
+ Marble, Description: Metamorphic rocks :: Building materials :: Carbonate rocks
  * Marble is dense, with a good range of colors. It can be carved or shaped, and is strong, and many think it beautiful.
+ Toy
  * Marbles are a type of toy. A 'toy' is something to play with. Toys are for children, adults, and animals. Before 1970, most toys were made of metal and wood. Now, they are mostly made of plastic. Sometimes they are made of electronic material.

### substance | marble:

Brecciated marble
* can have a marvellous appearance.
+ Breccia, Ornament: Sedimentary rocks
  * Brecciated marble can have a marvellous appearance. The Pantheon in Rome is full of the most wonderful marble, many of which are breccias.

Cultured marble
* blend of natural marble dust and tough polyster binders.
* is plastic and natural marble is stone.
