Keramikskaller

Keramikskaller are fragments or sherds of ceramic vessels. The term is used especially in Danish and Norwegian archaeological and museum contexts. They represent the broken pieces left after vessels were discarded, broken, or deliberately damaged, and they form the most common type of ceramic evidence recovered from sites.

Materials and forms: Keramikskaller vary by ware type, including earthenware, stoneware, and porcelain, as well as by temper, glaze, and decoration. They can range from small slivers to large rim or base fragments. The presence or absence of glaze, painting, incised patterns, or applied handles helps identify vessel style and potential function.

Identification and analysis: Specialists classify sherds by fabric (the clay and inclusions), temper, decoration, and rim or base forms. Comparative collections and reference typologies allow researchers to infer vessel type, production technique, date, and possible provenance. Fabric analysis and, where possible, residue studies can shed light on raw material sources and use.

Archaeological significance: Keramikskaller provide essential evidence about past economies, technology, and daily life. They help reconstruct trade networks, production centers, and dietary practices. Context—such as stratigraphic position, associated finds, and site function—guides interpretation and dating.

Preservation and handling: Cleanings should be gentle, using soft brushes and water if needed; avoid harsh chemicals. Keep records of provenience and context, and store fragments in labeled, padded containers to prevent further damage.

Modern uses: In contemporary craft and education, ceramic shards are used in mosaics and display installations. Museums preserve sherd collections to illustrate pottery technology and material culture.
