This morning when I was cleaning the firebox out, I noticed a couple of solid items of what looked like rock among the pile of ash in the firebox. I recently switched brands of lump charcoal, but have never noticed this before.
Has anyone else noticed rocks among their ash when using lump charcoal?
I am assuming that these pieces are part of the chemical reaction of the carbonization of the lump coal.
But, they look a lot like the landscaping rock that I have in the backyard.
BTW, I am attempting my first smoked ground turkey meatloaf. Wish me luck!
