Fountains built in the United States between 1900 and 1950 mostly followed European models and classical styles. For example: The handsome Samuel Francis Dupont Memorial Fountain (aka Dupont Circle Fountain), in Dupont Circle, Washington D.C., was designed and created by Henry Bacon and Daniel Chester French, the architect and sculptor of the Lincoln Memorial, in 1921, in a pure neoclassical ...
It seems that the copper was not used for the miners' tools. However copper chisels and discarded axes could be utilized as wedges. [16] Other evidence: The presence of coal and charcoal, crucial for the firing (fire-setting) and furnace (fuel), is habitual. Leather sacks (at Ai Bunar) and shoulder baskets (at Copa Hill) were used to transport ...
The concept of the Copper Age was put forward by Hungarian scientist Ferenc Pulszky in the 1870s, when, on the basis of the significant number of large copper objects unearthed within the Carpathian Basin, he suggested that the previous threefold division of the Prehistoric Age – the Stone, Bronze and Iron Ages – should be further divided ...

A fire pit can vary from a pit dug in the ground (fire hole) to an elaborate gas burning structure of stone, brick, and metal. Certain contemporary fire pit styles include fire bowls that can either be set in the ground or ...
A Bronze Age fire-set pit. Fire-setting is a method of traditional mining used most commonly from prehistoric times up to the Middle Ages. Fires were set against a rock face to heat the stone, which was then doused with liquid, causing the stone to fracture by thermal shock. Rapid heating causes thermal shock by itself—without subsequent ...
Thousands of copper mining pits have been found along the shores of Lake Superior, and Isle Royale. These pits may have been in use as far back as 8,000 years ago. This copper was mined and then made into objects such as heavy spear points and tools of all kinds.
This fact, correlated with the dramatic decrease in copper production, may indicate a possible displacement of copper and bronze artifacts by iron ones (Forbes 1957, 64; Bayley et al. 2008, 50). By the end of the 9th century, economic, and social conditions dictated a greater need for metal for agriculture, arms, stirrups , and decoration.
