looks like a place i got some from before, it was heater coal and fist size chunks, cracks and pops alot and dirty , but gets hot...
once again not sure if its the same place, its been 5 years or so ago....
as for stalite coal, I got some the other day for my class with Brian, it's full of clinker and smokes a lot, but is better than no coal at all!
and you can weld with it, also burns real fast!

Jody
