I went to my local vendor where I always purchased my sand blasting sand, well not anymore... they no longer carry any silica or quartz based products, now all they have is "black beauty" blasting media
it is coal slag, which at first thought would be ewwwwwwwwww (i had a coal fired furnace once upon a time) but on second thought... it might just work, it would seem like it should be inert
anyone have any experience with it?
basically just curious at this point
TIA,
Av
