Materials
Stone is the one category of material which is used by (virtually) all human cultures and, for the vast majority of the human past, is the only record of human behaviour. The end of prehistory does not signify the end of stone working; stones were knapped in Medieval Europe, well into the 19th century in many parts of Europe and the Americas. Contemporary stone tool manufacturers often work stone for experimentation with past techniques or for replication.
Flint and chert are the most commonly knapped materials and are compact cryptocrystalline quartz. The difference between the two terms is colloquial, and flint can be seen as a variety of chert. In common usage, flint may refer more often to high quality material from chalky matrix (i.e. "chalk flint" as found in Britain) and chert refers to material from limestone matrices. To avoid this, the term "silicate" may be used to describe the family of cryptocrystalline quartzes that are suitable for knapping. As well as cryptocrystalline quartz, macrocrystalline quartz (both vein quartz and rock crystal) was a commonly used raw material around the globe.
In North America, Central America, and other places around the world, such as Turkey and New Zealand, obsidian, or volcanic glass, was also a highly sought-after material for knapping and was widely traded. This is due to the quality of the stone, the razor sharpness of edges that can be created, and the fact that it fractures in highly predictable ways.
Soapstone, or steatite, has been a popular rock for grinding and carving among many cultures worldwide. It has been used for production of such disparate items as vessels/bowls, pipes, cooking slabs, and sculptures.

Famous quotes containing the word materials:
“Kicking his mother until she let go of his soul
Has given his a healthy appetite: clearly, her role
In the New Order must be
To supply and deliver his raw materials free;”
—W.H. (Wystan Hugh)
“Herein is the explanation of the analogies, which exist in all the arts. They are the re-appearance of one mind, working in many materials to many temporary ends. Raphael paints wisdom, Handel sings it, Phidias carves it, Shakspeare writes it, Wren builds it, Columbus sails it, Luther preaches it, Washington arms it, Watt mechanizes it. Painting was called “silent poetry,” and poetry “speaking painting.” The laws of each art are convertible into the laws of every other.”
—Ralph Waldo Emerson (1803–1882)
“In daily life what distinguishes the master is the using those materials he has, instead of looking about for what are more renowned, or what others have used well.”
—Ralph Waldo Emerson (1803–1882)
