SciencePrehistoric (~10,900 BCE, Younger Dryas period)Abu Hureyra, Syria (Levant)high confidence

Soil samples from Abu Hureyra contained melt glass—vaporized soil that rapidly solidified—found alongside seeds, cereal grains, and splattered throughout adobe buildings, with most fragments measuring 1–2 millimeters across.

Notes on verification

Multiple independent sources (Smithsonian, Eos, Syfy Wire, UCSB news) corroborate the specific details of melt glass composition, size, and location alongside seeds and adobe. Underlying peer-reviewed paper (Moore et al. 2020, Scientific Reports) confirms meltglass presence, though the precise 1-2mm size detail comes from science journalism rather than the paper's abstract directly.
