Museum Discussion / Re: Coal Dust to Coal Bricks

Has anyone tried to make a batch of coal bricks? I am wondering if it works and is worth the effort.
Formula: 6 parts coal dust, 1 part saw dust (optional), 1/4 part cement. Add enough water to make crumbly mix. Pack in form, then unform and set aside to dry.
