Don't worry about it. Every year, during a summer's walling activity - build maybe a hundred yards of wall, shift a hundred + tonnes of stone - I'd wear out fifteen to twenty pairs of heavy duty gardening gloves. One year I kept the remnannts and photographed them all for an early style web diary. One of the pairs were blue - hence the Username BlueGloves.

Rob Ixer was one of the four (?) active members of the Early Metals Research Group (EMRG). I wrote to him at a northern university (I think) saying "I've found a copper mine very probably exploited during the EBA, do you want a sample of its slag for isotope analysis?" He didn't write back so I moved him to the twonk category!
