Almost no site in Mesoamerica is without obsidian, called "Itztli" in the Nahuatl language. It was an item that had both frequent, common uses and ritual use. Obsidian was available to all households and was found in hunting, agriculture, and many other everyday situations. Examples of possible obsidian tools are knives, lance and dart points, prismatic blades sometimes used for woodworking or shaving, bone working tools, bifaces, retouched flakes, and spearheads for ritual warfare. Blades have been found in situ with rabbit, rodent, ...

Conchoidal fracture describes the way that brittle materials break when they do not follow any natural planes of separation. Materials that break in this way include flint and other fine-grained minerals, as well as most amorphous solids such as obsidian and other types of glass. It can also occur in other types of material under favorable circumstances. It was widely used in the stone Age to make sharp tools, and minerals that fracture in th ...

A cryptocrystal is a rock whose texture is so finely crystalline—that is, made up of such minute crystals—that its crystalline nature is only vaguely revealed even in a thin section by transmitted polarized light. Among the sedimentary rocks, chert and flint are cryptocrystalline. Also a form of diamond, known as carbonado, is cryptocyrstalline. Lava flows, especially of the acidic type such as felsites and rhyolites, may have a cryptocrystalline ground mass as distinguished from pure obsidian (acidic) or tachylite (basic), which

Obsidian was widely distributed throughout Mesoamerica by trade. Its importance to Mesoamerican societies has been compared to the value and importance of steel to modern civilization. However, archeology provides varied evidence of the individual value placed on obsidian. For example during the Formative period, obsidian was a rare item in the lowland areas, found predominately in elite and ritual contexts. In many Maya excavations evidence of obsidian is likewise found most frequently in privileged settings; as the Late Classic period prog ...

Obsidian is a legendary Cybertronian general who scored countless victories alongside his consort Strika. The two were captured by Megatron, who placed their sparks in Vehicon bodies. Obisidian became a helicopter, leading the aerial forces in place of the fallen Jetstorm. He quickly proved a dangerous foe to the Maximals, though during Megatron's absence and apparent death he joined them. When Megatron returned, Obisidian resumed command of the Vehicon air drones. He disappeared along with Strika during the final battle, and reportedly returned and refused reformatting as ...

Obsidian is relatively easy to work, aiding its prolific use throughout Mesoamerica. Obsidian is obtained by quarrying a source site. Pieces then are shaped by fracture as in the production of blades or knives. It may be also be formed by pecking and grinding, producing animal figurines, beads, labrets, ear ornaments, and other erratics. Pressure flaking blades from a prepared core was a common practice. Edge-rejuvenation or resharpening of blades was performed to prolong the lifespan of many pieces. Modern attempts to recreate production te ...

Already in the Stone Age Monte Arci played an important role. The old volcano was one of the central places where obsidian was found and worked for cutting tools and arrowheads. Even now the vulcanic glass can be found on the sides of the mountain. The Archeological Museum of Sassari displays ceramics from the Copper or Aneolithic Age (2600 BC). ...

The prehistorical era of Sardinia is characterised by the typical structures in stone that are called Nuraghe. There are about 7000 of these structures, more or less complex. The most famous is the complex of Barumini in the province of Cagliari. The Nuraghe were built in the period from about 1800 to 250 BC, with the climax between 1200 and 900 BC. Next to that holy waterplaces have been built (for example Santa Cristina, Sardara) and the grave structures called Dolmen. It is known that the Sardinians already had conta ...

In 1979 human remains were found that were dated to 150,000 BC. The first men to settle in Gallura and Northern Sardinia probably came from Italian peninsula, possibly Tuscany. The central region may have been populated by people arriving from the Iberian Peninsula through the Balearic Islands. Prehistoric arrowheads (3rd millennium BC) and sculptures of the Mediterranean Mother Goddess (now in the Archeological Museum of Cagliari) were retrieved which demon ...

From the 8th century BC, Phoenicians founded several cities and strongholds on Sardinia; Tharros, Bithia, Sulcis, Nora and Karalis (Cagliari). The Phoenicians came originally from Lebanon and traded in the Mediterranean. They settled everywhere in the region. Sardinia had a special position because it was central in the western Mediterranean between Carthage, Spain, the Rhone river and the Etruscan civilization area. The mining area around Iglesias was important for the metals (lead and zinc). The cities were founded on strategic points, oft ...

The human history of the park dates back 12,000 years. It was known to the original natives as "Mitzi-a-dazi," the "River of Yellow Rocks," because of the hydrothermally altered iron-containing yellow rocks in the Grand Canyon of the Yellowstone (many people incorrectly believe that the yellow color is from sulfur). The Native Americans that hunted and fished in the Yellowstone region also utilized the significant amounts of obsidian found in the park to make cutting tools and weapons. In fact, arrowheads made of Yellowstone obsidian ...

After the fall of the Roman Empire, Sardinia was subject to several conquests. In 456, the Vandals occupied the island coming from North Africa, after which the Byzantines liberated the island and made it part of the Byzantine Empire. From 711, the Saracens harassed the population of the coastal cities. For that reason in the ninth century Tharros was abandoned in favor of Oristano, after more than 1800 years of occupation. The aid of the maritime republics of Pisa and Genua was called in the struggle against the Arabs. From 1063 on t ...

Between 1718 and 1861 (the unity of Italy), Sardinia and Piedmont formed the Kingdom of Sardinia. The development of the infrastructure was slow. Under Carlo Felice, the most important road was built from south (Cagliari) to north (Sassari). It still bears his name. In 1883 the first trains travelled between Cagliari and Sassari and under Mussolini the swamps around Oristano were laid dry and the foundation of the most successful agrarian community was laid, Arborea. Mussolini also founded Carbonia, the centre of the mining activity. After t ...

Vitrification is a proven technique in the disposal and long-term storage of nuclear waste or other hazardous wastes. Waste is mixed with glass-forming chemicals to form molten glass that then solidifies, immobilizing the waste. The final waste form resembles obsidian and is a non-leaching, durable material that effectively traps the waste inside. The waste can be stored for relatively long periods in this form without concern for air or groundwater contamination. According to the Pacific Northwest National Labs, "Vitrification locks dangero ...

Trade originated with the start of communication in prehistoric times. Trading was the main facility of prehistoric people, who bartered goods and services from each other. Peter Watson dates the history of long-distance commerce from circa 150,000 years ago.[1] Trade is believed to have taken place throughout much of recorded human history. There is evidence of the exchange of obsidian and flint during the stone age. M ...
