They relied on open-air furnaces constructed from clay, which allowed for sufficient heat to melt copper ores.

Key methods included the use of basic bellows to increase airflow and temperature, enabling better smelting conditions. The process typically involved several steps: ore crushing, roasting to remove impurities, and then smelting in a shallow furnace. The Sumerians also employed a crucible technique to refine copper, highlighting an early understanding of thermal control.

• Ore was first crushed into smaller pieces to facilitate chemical reactions.
• Roasting involved heating the ore in open fires to transform sulfides into oxides.
• Copper was then smelted at temperatures estimated to reach around 1,200°C.
• The use of simple bellows helped sustain and regulate the high firing temperatures needed.

These early techniques laid the foundation for more advanced metallurgy in later periods and marked a significant technological achievement in Sumerian ancient technology.

The Process of Copper Smelting in Ancient Sumer

Ancient Sumerian copper smelting involved several carefully controlled steps to extract and refine metal from ore. The process began with the careful selection of copper-rich mineral deposits, often found near riverbeds or mountain regions. Workers would crush and calcine the ore to remove impurities and prepare it for smelting.

The next stage involved heating the processed ore in a crucible or furnace at high temperatures, utilizing a basic but effective combustion method. Early Sumerians used bellows to increase airflow, reaching temperatures sufficient to melt copper mineral concentrate. The molten metal would then collect at the bottom of the furnace, with slag and impurities rising to the surface.

The copper was subsequently poured into molds to form ingots or tools. Although the precise details of Sumerian smelting technology are not fully documented, evidence suggests a mastery of controlling temperature and airflow, essential for efficient extraction. These early techniques laid the groundwork for later advancements in metallurgy within the region.
