In slip casting a ceramic slurry which has a moisture content of 20 to 35 percent is poured into a porous mold. According to this definition elemental carbon is a ceramic. Slurry forming of ceramics generally is accomplished using slip casting gelcasting or tape casting. Additionally carbon based materials such as carbon fiber carbon nanotubes and graphene can be considered ceramics.
