Early Bronze Age Pottery Covered with Lime-Plaster: Technological Observations

With the emergence of urban culture in the southern Levant in the Early Bronze Age, new types of pottery and ceramic techniques appeared, among them pottery (usually combed) coated with a white material. A selection of sherds from Early Bronze strata was studied in an attempt to analyze this material. Using microscopy and various other methods, the authors were able to determine that the white material was a lime-plaster applied to the vessels after firing. The paper contends that the most likely reason for applying the lime-plaster was functional—to decrease permeability and protect the contents of the vessels.
