Node sources
- The Earliest Lead Object in the Levant (PLOS ONE / PubMed Central, 2015, primary_paper) • Supports: node
Locator: The paper identifies a late fifth-millennium BCE lead object from Ashalim Cave and argues it was made of almost pure metallic lead likely smelted from lead ore. - Lead processing (Encyclopaedia Britannica, 2026, textbook) • Supports: node
Locator: Britannica summarizes lead processing and ancient uses, supporting the broader lead-working scope beyond the earliest smelted object.
