Separate from maker’s marks were ownership marks—symbols applied by households to declare property. These marks might be added after purchase, sometimes after firing, scratched into already-hardened surface or painted on exterior. The rougher appearance of these secondary marks distinguished them from maker’s marks incorporated during manufacturing.
The household marks served practical purposes in communal settings. When multiple families shared storage facilities or when pots were lent between households, the marks prevented confusion about ownership. The mark declared “this pot belongs to this family,” allowing it to be returned properly after use.
Some ownership marks were defensive—protective symbols meant to deter theft or to identify stolen goods. A thief might scrape off ownership marks, but distinctive marks etched deeply were difficult to remove completely, traces remaining that could identify stolen pottery and convict thieves.
The marks also served magical functions—certain symbols were understood to protect contents, to prevent breakage, to ensure the pot served its purpose reliably. These protective marks operated on spiritual level, the symbols themselves carrying power that enhanced pot’s physical properties through supernatural means.
