# Iron Smelting
# Iron Smelting
## Overview
The development of iron smelting technology (~1200 BCE onward) ushered in the Iron Age, making metal tools and weapons accessible beyond elite classes and transforming agriculture, warfare, and society.
## Key Facts
- Transition period: ~1200–800 BCE (varies by region)
- Earliest iron smelting: Anatolia (Hittites), ~1500 BCE (limited use)
- Widespread adoption: After the Bronze Age Collapse (~1200 BCE)
- Key innovation: Carburization (adding carbon to create steel)
## Development
- Meteoric iron used before smelting was developed
- Hittites may have been early innovators, though evidence is debated [^1]
- Iron became widespread after the Bronze Age Collapse disrupted tin trade routes
- Chinese independently developed cast iron by ~500 BCE (bloomery iron in the West until medieval period) [^2]
## Impact
- Democratized access to metal tools (iron ore is abundant, unlike tin)
- Improved agricultural productivity (iron plows)
- Transformed warfare (iron weapons, armor)
- Enabled deforestation and land clearing at scale
