Hello modelers, got a short question to ask, but does anybody know how to make realistic coal from general use salt. I would love to use it in an existing layout, ideally in my coal yard, wagons and Staithes. I have already tried weathering salt techniques on an open wagon, 6 plank, and worked nicely. please post your suggestions on what I could do, Any more suggestions for me, add them too as this will help very much. Cheers guys.
