Definition of "potsherd"

[W]ho can deny but that the rod of Gods mouth is indeed Virga virtutis, a rod of strength, an iron rod, able to deale with all humane reaſonings, as a hammer with a potſherd, which though to the hand of a man it may feele as hard as a rocke, yet is too brittle to endure the blow of an iron rod?

[I]n the case of pottery, it [epigraphy] is usually taken to include graffiti scratched with a sharp point, and even painted inscriptions which are made before firing as part of the design of a vase, but not written documents (ostraka), in which pot-sherds are merely used as a material to write on instead of papyrus.

I have been asked about the single most important artifact that I have seen. It is a single broken piece of pottery no bigger than a couple of inches, but its interpretation makes it one of the most significant artifacts in Jewish history. It is an inscribed potshard (a fragment of pottery) from Masada (in Israel) marked with the name "ben Yair." […] While it remains a single potshard marked in ink, it is a powerful symbol of what motivates archaeologists in the field: a simple object that signifies an entire historical event.
