XXpot-shurd (cheres): A piece of earthenware (Job 2:8; Ps 22:15; Isa 45:9). the Revised Version (British and American) renders the word in Prov 26:23, "an earthen vessel," and in Job 41:30 substitutes "sharp potsherds" for "sharp stones." Sirach 22:7 refers to the art of "gluing a potsherd (ostrakon) together."
