The great bituminous seam near Pittsburgh, Pennsylvania was struck in 1784.

Cornwall Heritage Trust ~ Preserving Cornwall's Story

In the eighteenth century copper mining was of much greater importance than tin; by the early nineteenth century Cornwall was the greatest producer of copper in the world. By 1740 deep mining of copper was underway, made possible by the invention of increasingly sophisticated pumping equipment to remove some of the water from underground.

HISTORY arizonamininghistory

Copper mining is still a major business in the state even though many mines played out and declined into the dry dusty land. The mining landscape of Arizona ranged from the desert floor to high in the mountains ranges of the state. Gold, silver, zinc, and lead have also played a part in the mining history of the state.

A Very Brief History of Kitchen Utensils Back Burner

The 19th century, particularly in the United States, witnessed a dramatic expansion in the number of kitchen utensils available on the market, such as labor-savers like potato peelers, jelly molds and salad spinners. Signs of dissatisfaction with copper utensils, which reacted with acidic foods, were emerging, and other metals gained popularity.

copper mining equipment used in the 20th century

Copper was the first metal to be used to make weapons and tools. Mining and smelting skills spread from Asia Minor to Central Europe 4000 years BC. Around 3000 BC, high-ranking men owned a copper axe, which was often buried with them. A copper axe was used not only for woodworking and felling trees but was also a powerful close-combat weapon.
