Clay? in my lump
annjamaican
Posts: 152
On a few occasions I found little lumps of what looks like clay and one piece that looks like some sort of igneous rock mixed in with the usable left over lump. Have you had this experience? What exactly is it? So far I've only used Royal Oak and BGE charcoal. Found it after cooking with both brands.

It's pieces of the kiln.

That's quite common for me anyway. I've always assumed they are pieces of hardened clay off the wood scraps and ground that got scooped up with the front loader. Lump making is a pretty dirty operation. In case you haven't yet then brace yourself for the rocks you will also find in the future!

Thanks guys. For a while I thought the BGE was falling apart. I literally felt every square cm of the internal Egg surface to make sure I wasn't killing it with my cooking.- Jamaican living in rural Western Washington

I have the same issue with Cowboy brand lump. Never saw these chunks in the Ozark Oak lump, but every cleanout with Cowboy brand has at least a couple of these in them. I've also found metal and what looked like a piece of asphalt.

I learned BGE and Royal Oak lump were made by the same company. I recently started using Rockwood (on my second bag) and haven't seen any foreign bodies but I'm sure if it's part of the kiln, then such a discovery will be inevitable.wlhyatt said:I have the same issue with Cowboy brand lump.

@annjamaican All lumps will have some "extras" in them on occasion. Some brands seem to have more. That perception may be real or it may reflect that certain brands sell more so reports of rocks etc are more common. Even Rockwood will include a rock every now and again.

In cooking, often we implement steps for which we have no explanations other than ‘that’s what everybody else does’ or ‘that’s what I have been told.’ Dare to think for yourself. -
You will....nobody brand is perfect. Hopefully it's rocks instead of chunks of the kiln though--refractory repairs are expensive. Metal banding is common as well. It's what holds the slabs together when they're placed in the kiln. The bands break from the heat and usually come out in a few long pieces, but sometimes they'll break into small pieces and get lost in the lump.annjamaican said:

The Rock in my picture looks a bit like a pre-diamond. Think if I apply some pressure it will become one?Southeast Florida - LBGE

Found a couple of big nails in the bottom of the egg, I figure the only way they got there was with the lump.

probably a chunk from the lining of the retort (or whatever the hell the kiln thing is called). looks like refractory lining material, or just a rock.
happens in every brand i have ever tried, one time or another.

Most likely hammered into a tree, the tree grew a knot around them, that knotty piece got rejected by the mill, scrap went to make charcoal. They were not revealed until after the charcoal burned from around them. There's not many other ways for them to show up unless they were nailed into a tree at some point. -
This is the weirdest thing I found. I tossed it in my garden ..

I would rather light a candle than curse your darkness.
