We submit to you herein just more evidence of the fact that our unjustly maligned Coal Ash can serve admirably, and be profitably employed, as a substitute raw material in the manufacture of kiln-fired ceramics, with the understanding that regular old "bricks", coarse as they might appear, do qualify as ceramics.
That fact was confirmed not all that long ago by our United States Navy, as seen in our report of:
West Virginia Coal Association | US Navy Makes Ceramics from Coal Ash | Research & Development; concerning: "United States Patent 5,521,132
- Ash-based Ceramic Materials; 1996; Assignee: The USA as Represented by the Secretary of the Navy; Abstract: A ceramic material made from raw coal fly ash".
