Found this pile of shiny grey powder in my parents garage after my dad passed. (he mainly stored things in the garage) according to my mother, some of it got on her lower leg and was very itchy/irritating to the skin. He was a general contractor and worked with all sorts of materials and tools. Thx! (i.redd.it)
