A while back I asked about using wax to make a sawdust brick. The answers I got were kind of what I was thinking. So I was thinking mixing flour and water then mixing in saw dust. The flour and water make a watery paste, when it drys it should bind the sawdust into a brick. Well I made one yesterday let it dry and burned it today. The sawdust was stuck together in a hard block. I let it burn for a while then looked at it nice chunk of red coal sitting there. I think that might be a way to use all the sawdust. I'm going to make a bigger one today.
