I just ended up with a bunch of charcoal sticks as a byproduct of another project and have been wondering what to do with them.
They're too appealing to just dump them on the garden like any other biochar. They're a pleasure to draw with, though I really don't sketch much.
I guess they go in the Art Supplies For Someday drawer.
I wonder if they would subtitute for bamboo charcoal to purify a jar of water.
I was firing a few small ceramic pieces in a dutch oven in a fire. I put sticks and leaves inside the dutch oven to see if they would do anything to the surface of the clay. It came out black.
The sticks were cute, they had shrunk down to perfect miniatures of themselves.
They were varied and not identifiable species, picked up from broken branches I had chopped & dropped. Most likely fruit wood (plum, cherry, apple), pecan, spicebush, fig.
I was worried about ruining my dutch oven, but I realized it has a curved bottom & won't work on my induction stove. So I'm no longer likely to use it in the kitchen. The fire took off the seasoning, but the metal seems fine.
I could see the wood gas coming out beneath the lid of the dutch oven and catching fire.
