Alkaline earth metal compound containing, other than glass, e.g., ettringite, gypsum, barium sulfate, anhydrite, etc.:

(under subclass 401) Subject matter wherein the composition contains an alkaline earth metal compound other than glass, e.g., ettringite, gypsum, barium sulfate, anhydrite, etc.

(1) Note. Glass is not sufficient to place a patent in this subclass unless an alkali metal is specifically recited. Mere recitation of glass will place the patent in the appropriate subclass under silicon below.
