One pound of unshelled black walnuts will yield about ž of a cup of nutmeat. Unlike other varieties of nut, black walnuts come packaged in small pieces because the nut must be crushed between rollers to get through the exceedingly hard shell.

The dark brown shell is so hard that when it’s pulverized, it can be used to seal rock fractures in oil well drilling, to clean jet engines, and for water filtration. Black walnut shells are also used as an ingredient in dental and cosmetic products. [111] December 2007
