Bad Black Stuff

Bad Black Stuff

PostBy: rberq On: Sun Feb 15, 2009 2:20 pm

Looks like high quality, glassy coal. Sharp edges on the smaller piece, like LsFarm says you could shave with. The big piece is about 2/3 the size of a golf ball. They went through 14 hours in the stove without being affected, then jammed the grates so I had to dump the fire. (Good thing I had kept the match that was left over last October). The pieces fractured easily when struck with a hammer, which provided a little satisfaction. So what is this stuff?

Looks like Obsidian.? (volcanic glass) Ancients used it for cutting tools, arrowheads etc.

That's a premium piece of anthracite, trouble is you may not get it to burn because it's so hard. You need more air and preferably an entire load of it, e.g the other coal will burn up and that will never ignite. If you got a whole load of that you'd be either pulling your hair out getting it to burn or be wishing every load was like that. It's a crap shoot...

I've actually had some trouble in the past delivering similar quality coal, the customers either loved it or hated it. It was either "that was the best coal I ever had" or "I can't get it to burn"The ones that could get the stove adjusted right to burn it loved it... That will give you the most output and will burn forever.

... or slag like we played in as kids. That's basically the same only man-made obsidian. There were a few steal foundries in Phillipsburg so there was a lot of this stuff around. They used it to fill in the crick banks (streams or creeks for those Colloquially Challenged :lol: ).

Notice how it breaks in curves, and the grain has a swirl pattern to it. Looks like a lump of black glass, but Richard knows a lot more about coal than I ever will.

A crick is what you swim in. When I was growing up I thought only city folk said creak. toothy

Could be something else but I've seen coal break like that, it fractures like glass if its the really hard variety.

Hmmmm. Maybe that's what I had a couple weeks ago. I loaded up the stove in the evening, no different from any other evening. An hour later I noticed it was burning hot, maybe 150 degrees hotter than I would expect. I kept checking the air inlet, looking at the gaskets, double-checking and triple-checking that the ash door wasn't jammed open. Still can't account for it, but I wish every load was like that!
