DEFINITION

Classification: 106/468

Clay or material derived from clay containing, e.g., bentonite, montmorillonite, etc.:

(under subclass 467) Subject matter wherein the composition contains clay or a material indicated to have been derived from clay, e.g., montmorillonite, bentonite, kaolin, etc.

(1) Note. Some clays, such as montmorillonites, bentonite, etc., contain an alkaline earth metal and therefor make a composition containing them proper for this subclass alone; however, note that kaolin would not bring a composition into this area unless the composition also contained an alkaline earth metal.
