Chainmail:any evidence for NON-riveted

[Dan Howard]

Simon James suggests that, besides a decorative function, this copper edging prevented sweat from corroding the iron.

I can't see how. Sweat soaks the padding underneath and reacts with the entire garment. The armpits are the most exposed to sweat, not the edges. The other problem with copper rings and copper riveting is that the galvanic reaction between iron and copper greatly accelerates the corrosion compared to iron-only mail. The Copper-alloy edging was employed purely for decoration. The trident pattern on one of the Dura shirts is confirmation of that.
