There is another subject on the Hand Fired Coal Stoves called "what do you do with all your fines."
Someone had posted a youtube video, showing how they did their fine bricks.
I used the same way, 6 meatloaf pans of fines, 1 meatloaf pan of sawdust, 1/4 meatloaf pan of cement and mixed very well, then added a little water to just make the mixture crumble.
Then place back in the meatloaf pans and flip over and let dry. I made 3 batches yesterday and they are still drying, of course the cold weather isn't helping much.
