A warning about using old coal in your forge
For years, I just used whatever bituminous coal I could get from the local yard in Toledo, never thinking about its age. Last spring, I grabbed a bag that had been sitting outside all winter and my fire was weak, sputtered a lot, and left a huge clinker. I found out damp, old coal loses a lot of its volatile gases. Now I always store it dry under a tarp and test a small batch first. Has anyone else run into problems with coal that wasn't fresh?
