Overview

Randomized trial investigates dyeing technologies in historical Lielvārde-type patterned sashes, suggesting European trade connections.

Key Points

  • The study aims to explore the dyes and dyeing technologies used in Lielvārde-type patterned sashes from Latvia.
  • Analyzed red wool yarns from five Lielvārde-type sashes using UPLC–DAD/MS dye analysis and ICP–QQQ elemental analysis.
  • Conducted reflectance-based colourimetric measurements and experimental dyeing.
  • Reviewed historical sources to document dye materials and technologies.
  • Identified cochineal-derived anthraquinone compounds in all analyzed samples.
  • Revealed the use of aluminium- and tin-based mordanting systems; first evidence for tin-based mordants in Latvian textiles was provided.
  • Proposed a production period for the sashes between late 1850s and 1870s, supported by historical documentation.
