# Titanium Particles from Cooper's Tie

Thomas G. Kaye, Cooper Research Team, n.d.. _citizensleuths.com_.

Reports SEM-EDS findings on particles lifted from the tie: unalloyed titanium, 400-series stainless steel smeared into titanium, spiral aluminium chips of 5000-series type, bismuth, and the ruling-out of titanium dioxide and titanium sponge. Interprets the wearer as someone around a metal fabrication or titanium plant.
