How did the Egyptians extract and smelt copper from its ore without being able to heat it above 850 degrees Celsius?

 The ancient Egyptians were able to extract and smelt copper from its ore without being able to heat it above 850 degrees Celsius using a process called reduction smelting. This process involves heating copper ore in the presence of a reducing agent, such as charcoal or coke, which removes the oxygen from the ore, leaving behind the pure copper metal.


Reduction smelting was a widely used method for extracting and smelting copper in ancient times, as it did not require high temperatures, which were difficult to achieve with the technologies available at the time. The process was carried out in a furnace, which was typically made of clay or brick and lined with a layer of refractory material to help retain the heat.


To extract copper from its ore using reduction smelting, the ore was first crushed and ground into a fine powder. This powder was then mixed with a reducing agent, such as charcoal or coke, and placed in the furnace. The furnace was heated to a temperature of around 850 degrees Celsius, and the reducing agent was used to remove the oxygen from the ore, leaving behind the pure copper metal. The smelted copper was then poured into molds to create ingots or other shapes, which could be used for various purposes.


Overall, the ancient Egyptians were able to extract and smelt copper using reduction smelting, a process that allowed them to extract the metal from its ore without having to heat it to very high temperatures. This process was an important technological achievement and played a crucial role in the development of ancient Egyptian civilization.
