Overview

Randomized trial identifies cochineal dye in Aztec spinning vessels, indicating advanced textile production techniques.

Key Points

  • This research aims to identify organic residues and dyes in archaeological spinning vessels from the Aztec period.
  • Used high performance liquid chromatography coupled with electrospray ionization quadrupole time-of-flight mass spectrometry (HPLC-ESI-QToF)
  • Analyzed spinning bowls from chinampa domestic units in Xochimilco dating to the Late Postclassic period (1400–1500 CE)
  • Focused on the recovery and identification of organic compounds linked to pigmented materials.
  • Confirmed the presence of cochineal dye through the identification of carminic acid and related organic compounds.
  • Provided material evidence for pigment use in traditionally textile-associated vessels.
  • Revealed insights into textile decoration practices and multifunctional use of spinning vessels in domestic settings.
