[expand]The clay marking employed various application methods:
The impressed stamps pressed patterns into wet clay—carved wooden or ceramic stamps created repeatable marks, the stamping technique allowed consistent symbol reproduction, the standardization was quality control. The impressed marks were durable identifiers, the stamping was efficient marking method producing uniform symbols across multiple vessels.
The incised lines cut symbols after forming—sharp tools scratched patterns into leather-hard clay, the incision technique allowed freehand drawing, the cut marks were flexible notation. The incised symbols enabled spontaneous marking, the scratched patterns accommodated non-standard information requiring custom notation.
The painted marks applied pigments to surfaces—colored slips or glazes created visible symbols, the painting technique distinguished marks through color variations, the chromatic notation was additional information layer. The painted marks announced information through color coding, the pigmented symbols created visible categories.
The molded patterns integrated marks during forming—symbols were incorporated into vessel shapes during construction, the molding technique made marks inseparable from vessels, the integrated notation was permanent identification. The molded marks prevented fraudulent alteration, the structural integration was authentication security.
The firing created permanent marks—heat treatment made symbols indelible, the firing process locked information permanently, the thermal permanence was record preservation. The fired marks survived extended use, the heat treatment was documentation durability.
